stdcall;
Set the camera billboard properties of the object and its rotation axis.
Parameters
aObjectIndex - A Reference to one of the previously created dynamic objects
aBBCamPosX, aBBCamPosY,aBBCamPosZ - current position of the camera
aBBCamUpX, aBBCamUpY, aBBCamUpZ - The up vector of the camera.
aAxisX, aAxisY, aAxisZ - the axis that the object should rotate on.
Remark
This flag is implemented for all dynamic objects except animated bone meshes. Only use this when billboard type is RGL-BBT-ARB-AXIS. NB : This is slightly slower than rglSetDynamicBillboardProp and should be avoided if at all possible.
