The HdRenderParam is an opaque (to core Hydra) handle, to an object that is obtained from the render ...
virtual unsigned int GetWidth() const =0
Get the buffer's width.
Class to identify a texture file or a texture within the texture file (e.g., a frame in a movie)...
virtual VtValue GetResource(bool multiSampled) const
This optional API returns a (type-erased) resource that backs this render buffer. ...
