TryGetSubmeshClassifications(MeshId, Allocator, uint, NativeArray<uint>, NativeArray<uint>)

public bool TryGetSubmeshClassifications(MeshId id, Allocator allocator, out uint elementsPerVector, out NativeArray<uint> vertexIndexVectors, out NativeArray<uint> classifications)

Parameters

id

MeshId
A MeshId obtained earlier through TryGetMeshInfos for which to retrieve classification information

allocator

Allocator
The Allocator type to use for the returned 
NativeArray
s

elementsPerVector

uint
The number of packed elements in 
vertexIndexVectors
to treat as one classification unit. Platform-specific; for example, some platforms may use 
1
for a single vertex per classification; others may use 
3
to represent a triangle face per classification.

vertexIndexVectors

NativeArray<uint>
The indices referring to Mesh vertices that the classifications apply to, coallated with 
classifications
.

classifications

NativeArray<uint>
The opaque classification enumerations returned by the provider for the defined vertex components above.

Returns

Type

Description

boolTrue if the retrieval is successful, otherwise False

Remarks

Use this to retrieve semantic classifications for vertex or vertex group components of the meshes tracked by the subsystem.
This method always returns new NativeArray<T>s, even when there are no results. The caller is responsible for disposing the returned NativeArray<T>, though specifying the appropriate Allocator will manage this for you.
