I have a requirement to determine the current transformation matrix
applicable to specific nodes in my Scene graph. Specifically I need
this information for use in the Intersection process.
My current approach uses an intersection traversal callback on the
specified nodes which calls pfGetTravMat to store the matrix.
The intersection process makes calls to pfNodeIsectSegs and/or
pfChanNodeIsectSegs several times as part of it's processing before I
do the processing which makes use of the stored transformation
matrices.
The problem I have is that the intersection traversal triggered by the
calls to pfNodeIsectSegs etc may not reach the nodes with my callback
attached.
Can anyone suggest a way of getting the current transformation matrix
for a specific node which doesn't have this problem?
TIA.
Mark.
