TODO: We need to distinguish between the primvar types here, we should tag each HdBufferSource and HdBufferResource with Constant, Uniform, Varying, Vertex, or FaceVarying and provide accessors for the specific buffer types.
Returns the GPU resource. If the buffer array contains more than one resource, this method raises a coding error.
HDST_API HdStBufferResourceSharedPtr GetResource | ( | TfToken const & | name | ) |
Returns the named GPU resource.
This method returns the first found resource. In HD_SAFE_MODE it checks all underlying GL buffers in _resourceMap and raises a coding error if there are more than one GL buffers exist.
|
inline |
Returns the list of all named GPU resources for this bufferArray.
