Point Cloud Visualizer 1.0+ For Blender

Display, edit, filter, render, convert, generate and export colored point cloud PLY files.

Works with any PLY file with ‘x, y, z, nx, ny, nz, red, green, blue’ vertex values. Vertex normals and colors are optional.

Point Cloud Visualizer

General info

Point Cloud Visualizer

Basic Usage:
  • Install and activate addon in a usual way.
  • Add any object type to scene.
  • Go to 3d View Sidebar (N) > Point Cloud Visualizer tab, click file browser icon, select ply file, click Load PLY. Reload button next to it reloads ply from disk.
  • Click Draw button to display point cloud, Erase to hide point cloud. Adjust percentage of displayed points with Display, point size with Size and point transparency with Alpha.
  • Display point normals as lines – click Normal icon, adjust line length with Length next to it.
  • Transforming parent object transforms point cloud as well.
  • Illumination ‘adds’ single artificial light on points, you can edit its direction and strength. Works only when vertex normals are present.
  • When vertex colors are missing, cloud will be displayed in uniform gray, in that case you can enable Illumination to have better cloud view
Display Options:
  • Display – percentage of displayed points
  • Size – point size in pixels
  • Alpha – global points alpha
  • Normals – display point normals as lines, adjust line length with Length next to it
  • Illumination – enable extra illumination, works only when vertex normals can be loaded
  • Light Direction – illumination light direction
  • Light Intensity – illumination light intensity
  • Shadow Intensity – illumination shadow intensity
  • Depth – enable depth debug shader
  • Brightness – depth shader color brightness
  • Contrast – depth shader color contrast
  • False Colors – display depth shader in false colors
  • Color A – depth shader false colors front color
  • Color B – depth shader false colors back color
  • Normal – enable normal debug shader
  • Position – enable position debug shader

Shaders

Point Cloud Visualizer

Clip

Shader with 6 clipping planes. Planes can be enabled/disabled independently with eye icon, first 3 values are plane normal (x, y, z), last value is plane distance from origin. These can be set from different object bounding box, choose object from scene in Object and hit Set Clip Planes From Object Bounding Box, object can then be hidden/deleted, set values will stay until operator is executed again. X reset all the settings to their defaults.

Point Cloud Visualizer

Point Cloud Visualizer

  • Enable Clipping Planes Shader – enable shader
  • Plane 0 – plane 0 normal (x, y, z), plane 0 distance from origin
  • Plane 1 – plane 1 normal (x, y, z), plane 1 distance from origin
  • Plane 2 – plane 2 normal (x, y, z), plane 2 distance from origin
  • Plane 3 – plane 3 normal (x, y, z), plane 3 distance from origin
  • Plane 4 – plane 4 normal (x, y, z), plane 4 distance from origin
  • Plane 5 – plane 5 normal (x, y, z), plane 5 distance from origin

  • X – reset all the settings to their defaults

Edit

Point Cloud Visualizer

Point Cloud Visualizer

Point Cloud Visualizer

Quasi point cloud Edit Mode. Hit Start and all points are converted to helper mesh with vertices and entered to mesh edit mode. You can transform, delete and duplicate vertices using regular Blender’s tools. If you want update displayed points, hit Update, when you are finished editing hit End to update points for a last time and delete helper mesh. If something went wrong, select main object with cloud and hit Cancel to reload original points, return interface to regular mode and attempt to clean helper mesh if it is still available.

  • To save edited point cloud, you have to use Export feature and check Use Viewport Points because edits are only in memory, if you close Blender, edits will be lost.
  • Point normals are not changed (at this time), if you rotate points, normals will be still oriented as before.
  • New points can be reliably (for now) created by duplicating existing points. If you create new points, they will all have the same random normal and random color.

Start – Start edit mode, create helper object and switch to it Overlay Alpha – Overlay point alpha Overlay Size – Overlay point size Update – Update displayed cloud from edited mesh End – Update displayed cloud from edited mesh, stop edit mode and remove helper object Cancel – Stop edit mode, try to remove helper object and reload original point cloud

Filter

Filter current point cloud, all changes are only temporary, original data are still intact. To keep changes, you have to export cloud as ply file.

Point Cloud Visualizer

Simplify

Simplify point cloud to exact number of evenly distributed samples. All loaded points are processed. Higher samples counts may take a long time to finish. Surely there are better (and faster) tools for the job, but.. Basically it takes some random point and set as accepted sample, then another set of random candidates, measure distance from already accepted samples and stores the one that is most distant as another accepted, repeat until number of samples is reached.

  • Samples – Number of points in simplified point cloud, best result when set to less than 20% of points, when samples has value close to total expect less points in result
  • Candidates – Number of candidates used during resampling, the higher value, the slower calculation, but more even
  • Simplify – run operator
Project

Project points on mesh (or object convertible to mesh) surface. Projects point along their normals until it hit surface or Search Distance is reached. You can choose between Positive (along normal direction), Negative (vice versa) or both. Optionally you can Discard Unprojectable points that was not possible to project and after projection Shift points a fixed distance along normal (positive value) or the other way around (negative value). Projected points can be optionally colorized by vertex colors, uv texture and vertex group from target mesh.

  • Object – Mesh or object convertible to mesh
  • Search Distance – Maximum search distance in which to search for surface
  • Positive – Search along point normal forwards
  • Negative – Search along point normal backwards
  • Discard Unprojectable – Discard points which didn’t hit anything
  • Colorize – Colorize projected points
  • Source – Color source for projected point cloud
    • Vertex Colors – Use active vertex colors from target
    • UV Texture – Use colors from active image texture node in active material using active UV layout from target
    • Vertex Group Monochromatic – Use active vertex group from target, result will be shades of grey
    • Vertex Group Colorized – Use active vertex group from target, result will be colored from red (1.0) to blue (0.0) like in weight paint viewport
  • Shift – Shift points after projection above (positive value) or below (negative value) surface
  • Project – execute operator
Boolean

Intersect or Exclude points with mesh object. Mesh have to be non-manifold.

  • Object – Mesh or object convertible to mesh
  • Intersect – Keep points inside mesh, remove points outside
  • Exclude – Keep points outside mesh, remove points inside
Remove Color

Remove points with exact/similar color as chosen in color picker (Eyedropper works too). Currently i can’t get to match sampled color from viewport with color in loaded cloud. Floating point error, incorrectly handled Gamma (at my side for sure), color management in Blender’s viewport or any combination of all, or something else.. Anyway, if you leave at least one delta at hue/saturation/value (whatever works best for given cloud) it should remove the color you picked.

  • Color – Color to remove from point cloud
  • Δ Hue – Delta hue
  • Δ Saturation – Delta saturation
  • Δ Value – Delta value
  • Select Color – Run operator and display selected points in viewport for review
  • X – Deselect
  • Delete Selected – Delete selected points
Merge

Load another ply and merge with currently displayed. Hit Merge With Other PLY, select ply file and load. New point will be appended to old, shuffled if shuffle is enabled in preferences.

  • Merge With Other PLY – run operator
Join

Join current active point cloud with another on different object. Object transformations are applied to clouds to look the same as before joining.

  • Object – select object with another point cloud to join
  • Join – run operator
Color Adjustment

Point Cloud Visualizer

Adjust exposure, gamma, brightness, contrast, hue, saturation, value or invert colors. Click Enable to enable color adjustment shader, adjust values as needed, click Apply to apply colors to points. Click Reset to set all to default value. Shader can be disabled without changes anytime unchecking Enable. When color adjustment shader is enabled, all other shaders are disabled.

  • Enabled – Enable color adjustment shader, other shaders will be overrided until disabled
  • Exposure – formula: color = color * (2 ** value)
  • Gamma – formula: color = color ** (1 / value)
  • Brightness – formula: color = (color – 0.5) * contrast + 0.5 + brightness
  • Contrast – formula: color = (color – 0.5) * contrast + 0.5 + brightness
  • Hue – formula: color.h = (color.h + (value % 1.0)) % 1.0
  • Saturation – formula: color.s += value
  • Value – formula: color.v += value
  • Invert – formula: color = 1.0 – color
  • Reset – Reset color adjustment values
  • Apply – Apply color adjustments to points, reset and exit

Render

Currently only sigle point cloud per render/frame is supported. Output image is RGBA 8bit PNG – transparent background with colored point cloud, which can be composed over something else later.

Usage:
  • Blend file has to be saved
  • Load and display ply first.
  • Make a camera and adjust as needed.
  • Select cloud parent object, set point size with Size or percentage of rendered points with Count
  • Set render path in Output.
  • Set render image size with Resolution X, Resolution Y and Resolution %.
  • At default resolution settings are taken from scene, to make them independent, click chain icon next to properties, correct aspect ratio is not calculated, if you link properties again, values are copied from scene.
  • If Illumination is enabled it will be rendered as well
  • If one of debug shaders is enabled, it will be rendered instead of regular shader
  • Hit Render or Animation
Render options:

Point Cloud Visualizer

  • Count – percentage of rendered points
  • Size – point render size in pixels
  • Supersampling – Render larger image and then resize back to anti-alias, 1 – disabled, 2 – render 200%, 3 – render 300%, etc.
  • Smooth Circles – Currently works only for basic shader with/without illumination and generally is much slower than Supersampling, use only when Supersampling fails
  • Output – path where to save rendered images, # characters defines the position and length of frame numbers, image is always saved, filetype is always png, accepts relative paths, upon hitting Render path is validated, changed to absolute and written back
  • Resolution X – image width in pixels
  • Resolution Y – image height in pixels
  • Resolution % – percentage scale for resolution
  • Resolution Linked – when enabled, settings are taken from scene, if not they are independent on scene, but aspect ratio is not calculated
Render smoothing/anti-aliasing notes:

Use Supersampling for most of the time with lowest value (to be exact, 2 works great) that look still good. If you run into problems due to very large supersampled image sizes Blender or hardware cannot handle, you can try to disable Supersampling and use Smooth Circles to draw smooth points directly in target resolution, but you are limited to basic shader and points before drawing have to be depth sorted manually which can be very slow with large point counts.

Convert

Point Cloud Visualizer

Point Cloud Visualizer

Convert point cloud to mesh. May result in very large meshes, e.g. 1m point cloud to cubes = 8m poly mesh. Depending on what point cloud data is available and desired mesh type, some options may not be enabled.

Conversion to instancer specifics: points are converted to triangle mesh object, vertex colors are baked to texture, extra instanced sphere object is added as child object of main mesh, material using baked colors is added to sphere and each instance inherits color of corresponding face it is instanced from.

Conversion to particles specifics: points are converted to triangle mesh object, vertex colors are baked to texture, particle system is added to mesh with one particle on each face, extra instanced sphere added as child object of main mesh and particle system is set to render that sphere, material using baked colors is added to sphere and each instance inherits color of corresponding face it emit from. Result is regular particle system which can be further edited, e.g. instance mesh changed, physics added etc.

Point Cloud Visualizer

  • Type – Instance mesh type, Vertex, Equilateral Triangle, Tetrahedron, Cube or Ico Sphere
  • All, Subset – Use all points or random subset of by given percentage
  • Size – Mesh instance size, internal instanced mesh has size 1.0 so if you set size to 0.01, resulting instances will have actual size of 0.01 event when cloud is scaled
  • Align To Normal – Align instance to point normal, e.g. tetrahedron point will align to normal, triangle plane will align to normal etc.
  • Colors – Assign point color to instance vertex colors, each instance will be colored by point color (except vertices)
  • Sphere Subdivisions – Conversion to instancer / particles only, number of subdivisions of particle system instanced ico sphere

Generate

Generate point cloud from mesh (or object convertible to mesh). To store point cloud, use Export to save as ply file.

Point Cloud Visualizer Point Cloud Visualizer

  • Source – Points generation source
    • Vertices – Use mesh vertices
    • Surface – Use triangulated mesh surface
    • Particles – Use active particle system
  • Particles (Source: Particles) – Particles source selection
    • All (Source: Particles) – Use all particles
    • Alive (Source: Particles) – Use only alive particles
  • Algorithm (Source: Surface) – Point generating algorithm
    • Weighted Random In Triangle – Average triangle areas to approximate number of random points in each to get even distribution of points. If some very small polygons are left without points, increase number of samples. Mesh is triangulated before processing, on non-planar polygons, points will not be exactly on original polygon surface.
    • Poisson Disk Sampling – Warning: slow, very slow indeed.. Uses Weighted Random In Triangle algorithm to pregenerate samples with all its inconveniences.
  • Approximate Number Of Points (Source: Surface) – Number of points to generate, some algorithms may not generate exact number of points.
  • Seed (Source: Surface) – Random number generator seed
  • Colors (Source: Vertices, Surface, Particles) – Color source for generated point cloud
    • Constant Color – Use constant color value
    • Vertex Colors – Use active vertex colors
    • UV Texture – Generate colors from active image texture node in active material using active UV layout
    • Vertex Group Monochromatic – Use active vertex group, result will be shades of grey
    • Vertex Group Colorized – Use active vertex group, result will be colored from red (1.0) to blue (0.0) like in weight paint viewport
  • Color (Source: Vertices, Surface, Particles) – Constant color
  • Exact Number of Samples (Source: Surface, Algorithm: Triangle) – Generate exact number of points, if selected algorithm result is less points, more points will be calculated on random polygons at the end, if result is more points, points will be shuffled and sliced to match exact value
  • Minimal Distance (Source: Surface, Algorithm: Poisson) – Poisson Disk minimal distance between points, the smaller value, the slower calculation
  • Sampling Exponent (Source: Surface, Algorithm: Poisson) – Poisson Disk presampling exponent, lower values are faster but less even, higher values are slower exponentially

When Source is Particles, for generating colors (apart from Constant color), non-overlapping UV layout is required (can be really bad, useless for real production).

Export

Export current point cloud as binary ply file with several options. If exporting modified (filtered) points, check Use Viewport Points, otherwise you will not get modified points. If exporting viewport points colors may slightly differ. Transformation and axis conversion can be applied on both loaded and viewport points.

Point Cloud Visualizer

  • Use Viewport Points – When checked, export points currently displayed in viewport or when unchecked, export data loaded from original ply file
  • Visible Points Only – Export currently visible points only (controlled by ‘Display’ on main panel)
  • Apply Transformation – Apply parent object transformation to points
  • Convert Axes – Convert from blender (y forward, z up) to forward -z, up y axes

Sequence

Load sequence of ply files to play in viewport. Load first frame as regular file and when Preload Sequence is clicked it tries to load all ply files matching selected ply filename, e.g. you select sequence-001.ply and all sequence-###.ply will be loaded from directory. Only last number in filename is considered. Numbers should start at 1. All other features works when animation is not playing, but all changes are lost when you change frame to another.

Point Cloud Visualizer

  • Preload Sequence – Load all matching ply files
  • Cycle Forever – Cycle frames if timeline is longer than number of loaded frames
  • Clear Sequence – Clear all loaded and return object to regular state i.e. you can load another ply, changes are kept etc.

External API

To display point cloud data from other addons/custom scripts.

import bpy
import numpy as np
from space_view3d_point_cloud_visualizer import PCVControl
o = bpy.context.active_object
c = PCVControl(o)
n = 100
vs = np.random.normal(0, 2, (n, 3))
ns = np.array([[0.0, 0.0, 1.0]] * n)
cs = np.random.random((n, 3))
# draw points
c.draw(vs, ns, cs)
# if some data like normals/colors are not available
c.draw(vs, None, None)
c.draw(vs, [], [])
c.draw(vs)
# it is also possible to pass nothing in which case nothing is drawn
c.draw()
# to stop any drawing
c.erase()
# to return object control to user
c.reset()

Addon Preferences:

Point Cloud Visualizer

  • Default – Default color to be used upon loading PLY to cache when vertex colors are missing

Known bugs:
  • If you duplicate object with cloud, duplicate will still control the original one until you load a different one. Currently there is no reliable way (as far as i know) to get unique id of an object and therefore no way to tell to which object stored properties (e.g. path to ply) belong.

Color Management Presets (for blender 2.80)

Presets support for Render > Color Management panel, nothing more, nothing less.. Comes with a few presets i use which are created upon activation.

Color Management Presets


Tube UV Unwrap (for blender 2.80)

UV unwrap tube-like meshes (all quads, no caps, fixed number of vertices in each ring)

Tube UV Unwrap

notes:

  • Works only on tube-like parts of mesh defined by selection and active vertex (therefore you must be in vertex selection mode) and the selection must have a start and an end ring. Tube-like mesh is: all quads, no caps, fixed number of vertices in each ring. (Best example of such mesh is mesh circle extruded several times or beveled curve (not cyclic) converted to mesh.) There must be an active vertex on one of the boundary loops in selection. This active vertex define place where mesh will be ‘cut’ – where seam will be placed.
  • Result is rectangular UV for easy texturing, scaled to fit square, horizontal and vertical distances between vertices are averaged and proportional to each other.

usage:

  1. tab to Edit mode
  2. select part of mesh you want to unwrap, tube type explained above
  3. make sure your selection has boundaries and there is an active vertex on one border of selection
  4. hit “U” and select “Tube UV Unwrap”
  5. optionally check/uncheck ‘Mark Seams’ or ‘Flip’ in operator properties

changelog:

  • 0.3.0 blender 2.8 update

Only active mesh is exported. Only single mesh is expected on import. Supported obj features: UVs, normals, vertex colors using MRGB format (ZBrush) or ‘Extended’ format (import only) where vertex is defined as (x,y,z,r,g,b).

Fast Wavefront^2

changelog:

  • 0.3.6 fixed export with applied modifiers
  • 0.3.5 api changes fixes
  • 0.3.4 ui
  • 0.3.3 fallback python export implementation in case cython module is not available

Import Agisoft PhotoScan Cameras

Import cameras from Agisoft PhotoScan xml. Works with xml version 1.4.0 which is exported from PhotoScan 1.4.x versions and xml versions 1.5.0 from Agisoft Metashape 1.5.x versions. If you want to have images actually aligned with model, undistort images first. This is done in PhotoScan by Export > Undistort Photos... Because you can’t in Blender set resolution for cameras independently, xml with different cameras or image resolutions might not work well.

Import Agisoft PhotoScan Cameras

usage:

  1. go to Properties > Scene > Import Agisoft PhotoScan Cameras panel
  2. Cameras XML: set path to xml
  3. set import options:
    • Camera Display Size: size of imported cameras in viewport
    • Load Camera Images: load images or not
    • Images Directory: path to directory with undistorted images
    • Image Extension: images extension, they all should be the same (currently)
    • Alpha: camera image alpha, 0.0 – 1.0
    • Depth: camera display depth, front / back
  4. there are some more optional properties:
    • Create Chunk Region Borders
    • Align to Active Object: if you import mesh from PhotoScan first, the transform it to correct size and orientation, this option will copy transformation from that mesh if it is active
  5. hit Import
  6. import done..
  7. now you can quickly swap cameras in alphabetical order in PhotoScan Cameras Utilities panel

changelog:

  • 0.1.3 ui
  • 0.1.2 compatibility with Agisoft Metashape XML (1.5.x)
  • 0.1.1 first release

Carbon Tools

Ever-evolving set of small tools, workflows and shortcuts focused mainly on processing photogrammetry scans.

Carbon Tools

Subtools

  • Extract selected part of mesh to a new object. If edges of extracted mesh are changed, it won’t be able to merge back seamlessly – use option to hide edges (lock button) to protect them.
  • Insert it back when finished editing.
  • Extract Non-Manifold elements with part of mesh around them (10x expanded selection) as subtool

Dyntopo

  • Dyntopo Setup – Quick setup for optimizing mesh resolution. Set desired Constant Resolution and Method and hit Dyntopo Setup Mode is switched to Sculpt with Dyntopo, brush is set to strength 0 – affecting only mesh resolution.
  • Dyntopo Live Settings – current settings which can be changed during sculpting

Texture Paint

  • Texture Paint Setup – Quick setup for retouching texture in Photoshop, set Resolution of exported images and hit TP Setup (Photoshop must be set in preferences as Image Editor)
  • External TP Live Commands: Quick Edit – export image and open in PS, Apply – project image back to model, Save All Images – save all edited textures

IO

  • Import from ZBrush (depends on other addon Fast Wavefront^2)
  • Export to ZBrush (depends on other addon Fast Wavefront^2)
  • Transformation: Selected > Active – Copy transformation from selected to active. Useful for setting correct scale and orientation after initial import from PhotoScan.
  • Matrix: Selected > Active – Select matrix source object first and then target object. Matrix will be copied while keeping visual transformation intact.
  • Export to PhotoScan (depends on other addon Fast Wavefront^2)

End

  • End ends current procedure: Dyntopo and Texture Paint back to Object mode and reset all settings

Utilities

  • Smooth / Flat shading, just shortcuts
  • UV Coverage calculate and print how much percent covers active uv layout
  • Seams From Islands mark seams from UV islands
  • Select Seams select seam edges
  • Seams > Wireframe copy seams edges to a new mesh object
  • Export UV Layout
  • Wireframe set display to shaded + wire + all edges and deselect object
  • Select Non-Manifold select non-manifold elements and optionally focus camera on them (eye icon)

Conversions

  • UVTex > VCols – Copy image colors from active image texture node in active material using active UV layout to new vertex colors
  • Group > VCols – Active vertex group to new vertex colors, vertex weight to rgba(weight, weight, weight, 1.0)
  • VCols > Group – Active vertex colors to new vertex group, vertex weight by color perceived luminance
  • Difference > Group – Calculate difference between two selected meshes and write as vertex group to active mesh. Selected is considered to be original, active to be modified. Objects should have the same transformation.

changelog:

  • 2.2.2 ui changes, mesh difference to group, calculate uv coverage
  • 0.2.1 uvtex / vcols / group conversions
  • 0.2.0 first release
