Properties

Optionalaabb

aabb?: FloatArrayParam

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

OptionalcolorsCompressed

colorsCompressed?: IntArrayParam

vertex RGB colors, quantized as 8-bit integers.

OptionaledgeIndices

edgeIndices?: IntArrayParam

edge indices.

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

id

id: string

ID for the geometry.

Optionalindices

indices?: IntArrayParam

primitive indices.

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

Optionalorigin

origin?: FloatArrayParam

TODO

positionsCompressed

positionsCompressed: IntArrayParam

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

Internally, the Viewer decompresses thses with SceneGeometryCompressedParams.aabb.

Vertex positions are required for all primitive types.

primitive

primitive: number

Primitive type.

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

OptionaluvsCompressed

uvsCompressed?: IntArrayParam

UV coordinates, quantized as 16-bit integers.

Internally, the Viewer de-quantizes these with SceneGeometryCompressedParams.uvsDecompressMatrix.

OptionaluvsDecompressMatrix

uvsDecompressMatrix?: FloatArrayParam

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