Geometry support #6
Description
Relevant info:
- https://discourse.threejs.org/t/three-geometry-will-be-removed-from-core-with-r125/22401
- In BufferGeometry, a vertex is saved using the
positionattribute - Faces are generated automatically from vertices but that also means repeating vertices since each face requires three of them
- To reuse vertex indices for faces, the
setIndexmethod of BufferGeometry needs to be used - If all else fails, use legacy Geometry to convert, or maybe learn from it
- Concern: morph targets
- For meshes with multiple materials see: https://threejs.org/docs/index.html#api/en/core/BufferGeometry.groups - to slice geometry into groups that belong to different material indexes
