I noticed that when I request the pfMatrix of a pfDCS via getMat and getMatPtr
it seems that the transformations (setRot, setTrans and setScale) that I may
have requested earlier have not yet been applied on the matrix. I end up having
the matrix from the previous frame. I guess for performance reasons Performer
computes the matrix only once somewhere before culling starts. I would be
interested to know where this happens exactly. Some of the viewpoints that I
have to set up depend on those matrices. Is there a way to force Performer to
update those matrices somewhere in APP before culling begins?

Regards,
