Re: Billboard Objects?

I'd like to suggest that the way to do Billboard objects is not to focus on
the thing being displayed, but on the transform. If we defined something
like

CameraTransform {
isA Transform
fields [ SFBITMASK axis ]
axis X|Y|Z # Specifies which axis to always
rotate to face the camera.
}

Note - that "rotate to face the camera" means to rotate so that the local
coordinate space of the object, matches that of the camera.
