Type	Name	Description
Mesh	unityMesh	Input mesh

Returns

Type	Description
Task<EncodeResult[]>	Encoded data (one per sub-mesh)

EncodeMesh(Mesh, QuantizationSettings, SpeedSettings)

Applies Draco compression to a given mesh and returns the encoded result (one per sub-mesh)

Declaration

public static Task<EncodeResult[]> EncodeMesh(Mesh unityMesh, QuantizationSettings quantization, SpeedSettings speed)

Parameters

Type	Name	Description
Mesh	unityMesh	Input mesh
QuantizationSettings	quantization	Quantization settings

EncodeMesh(Mesh, MeshData, Vector3, float, int, int, int, int, int, int)

Applies Draco compression to a given mesh/meshData and returns the encoded result (one per sub-mesh) The user is responsible for acquiring the readable MeshData and disposing it. The quality and quantization parameters are calculated from the mesh's bounds, its worldScale and desired precision. The quantization parameters help to find a balance between compressed size and quality / precision.
