Definition

AllocateTempMesh(int, int, NativeSlice<Vertex>, NativeSlice<ushort>)

Allocates the specified number of vertices and indices from a temporary allocator.
public void AllocateTempMesh(int vertexCount, int indexCount, out NativeSlice<Vertex> vertices, out NativeSlice<ushort> indices)

Parameters

vertexCount

int
The number of vertices to allocate, with a maximum limit of 65535 (or UInt16.MaxValue).

indexCount

int
The number of triangle list indices to allocate, where every three indices represent one triangle. Therefore, this value should always be a multiple of three.

vertices

NativeSlice<Vertex>
The returned vertices.

indices

NativeSlice<ushort>
The returned indices.

Remarks

You can only call this method during the mesh generation phase of the panel and shouldn't use it beyond.

AllocateTempMesh(ExtraVertexChannels, int, int, UIMesh)

Allocates a temporary UIMesh with mandatory vertex+index storage and one extras slice per channel set in 
extraChannels
.
public void AllocateTempMesh(ExtraVertexChannels extraChannels, int vertexCount, int indexCount, out UIMesh mesh)

Parameters

extraChannels

ExtraVertexChannels

vertexCount

int

indexCount

int

mesh

UIMesh

Remarks

Pass 
vertexCount
= 0 to skip the vertex+extras allocation, or 
indexCount
= 0 to skip the index allocation. Channels not requested are returned as default (empty) slices.
