Need to set a viewpoint position based on an offset from the model the
viewpoint is viewing. I want to specify the offset in the model
coordinate system. For example: specifying 1,0,0 the viewpoint would
be looking down the models x axis, specifying 0,1,0 the vp would be
looking down the y axis. How do I convert these offsets from the model
coordinates to OSG world coordinates so that I can do following:
offsetInWorldCS = (some coversion) * offsetInModelCS
vpPositionInWorld = offsetINWorldCS
Is there a reason why the local-to-world matrix wouldn't work for you?
