Houdini 20.5 Nodes Geometry nodes

Labs Terrain Analysis (Beta) 1.0 geometry node

This node analyzes a HeightField and generates cost and avoidance attributes.

On this page
Since 19.5

This node takes a HeightField as the main input, and analyzes it to generate cost and avoidance attributes. There is an option to split the terrain into tiles to multithread the process. There are also options to change the resolution of the terrain mesh conversion that is required for the analysis, as well as various input methods for the avoidance.

Parameters
