Mesh.MeshData.GetVertexAttributeDimension

切换到手册
public int GetVertexAttributeDimension (Rendering.VertexAttribute attr);

参数

attr The vertex attribute to get the dimension of.

返回

int Returns the dimension of the vertex attribute. Returns 0 if the vertex attribute is not present.

描述

Gets the dimension of a given vertex attribute in the MeshData.

Most vertex attributes have a standard data layout. For example, a normal is a 3-component vector. Some vertex attributes (usually texture coordinates) have more than one possible data layout. For example, SetUVs accepts either 2 dimensional, 3 dimensional or 4 dimensional texture coordinates. You can use this function to query the layout of a given vertex attribute.
