Class SceneGeometry

Axis-aligned, non-quantized 3D boundary of the geometry's vertex positions.

Vertex RGBA colors, quantized as 8-bit integers.

True if this SceneGeometry has been destroyed.

Edge indices.

This is either an array of 8-bit, 16-bit or 32-bit values.

ID for the geometry.

primitive indices.

This is either an array of 8-bit, 16-bit or 32-bit values.

The SceneModel that contains this SceneGeometry.

Vertex normals, octahedral-encoded as pairs of 16-bit unsigned integers.

When defined, the renderer reads these per-vertex and uses them for smooth shading; when undefined, fragments derive a flat face normal from view-space position derivatives.

The count of SceneMeshes that reference this SceneGeometry.

3D vertex positions, quantized as 16-bit integers.

Internally, the Viewer dequantizes these using SceneGeometry.aabb, which provides their unquantized 3D boundary.

Vertex positions are required for all primitive types.

Primitive type.

Possible values are SolidPrimitive, SurfacePrimitive, LinesPrimitive, PointsPrimitive and TrianglesPrimitive.

The global ID of this SceneGeometry, unique among all SceneGeometrys within the Scene, which is the concatenation of the SceneModel's ID and this SceneGeometry's ID, separated by "__".

UV coordinates, packed as 32-bit floats (one Float32Array of length 2 × vertexCount). UVs ship to the GPU uncompressed so tiling values (UVs outside [0, 1]) survive intact — the shader applies a per-fragment fract() before transforming into the mesh's atlas sub-rect.

4x4 matrix to de-quantize the geometry's UV coordinates, when UVs are provided.
