public int GetVertexAttributeStream (Rendering.VertexAttribute attr);

パラメーター

attr The vertex data attribute to check for.

戻り値

int Stream index of the data attribute, or -1 if it is not present.

説明

Get the vertex buffer stream index of a specific vertex data attribute on this MeshData.

Meshes usually use a single vertex buffer stream, but it is possible to set up a vertex layout where attributes use different vertex buffers (see SetVertexBufferParams). When you use such a layout, use this function to query which vertex buffer stream a given attribute is part of.

Note that this function returns the index of the stream, without specifying where the attribute is within the stream. To identify the location of a given attribute in the stream, use GetVertexAttributeOffset.
