Terrain Slope Analysis for Forma
FormaSlope01Slope analysis on Autodesk Forma terrain, as an embedded extension in the Forma UI
Overview
An Autodesk Forma embedded-view extension for interactive slope analysis and pick-point grade labeling on terrain surfaces. It pulls terrain triangles from the Forma geometry API, builds a BVH-accelerated THREE.js scene for fast spatial queries, and raycasts downward from a picked point to derive slope percentage from the face normal. Results render back into the Forma viewport as colored marker geometry and a terrain heatmap.
What it does
- Terrain slope querying
- Pick-point grade labels
- BVH raycasting
- Heatmap on terrain
