Описание : L-systems offer a way to procedurally model geometry. If you’ve ever wanted to create foliage, complex fractal geometry, or spline-based models from scratch, then L-systems offers you a way of doing so through understanding it’s own language.
In addition to L-systems, you’ll learn more about instancing and how to work efficiently with Houdini. We’ll be rendering out millions of polygons with both Mantra and Redshift while aiming to optimize render times as much as possible. These optimizations are applicable across a wide variety of 3D topics.
