Hi JP Thanks for the quick response.
I'm not used to these forum things so the format of my response will probably be odd, anyway... > what are you setting > for near/far in the DO_NOT_COMPUTE_NEAR_FAR case? What is your > nonLinearRange value? Is it dependent on camera field of view? In both cases I'm getting my the near/far from rttCamera->getProjectionMatrixAsFrustum. The values returned in the the DO_NOT_COMPUTE case are 1.0 and 10000.0 and the linearised ranges seem to agree with this. The camera field of view is not changing. I haven't looked at the actual values only their differences. I had hoped that some of my assumptions were wrong, but following your response it seems that I'm going to have to do this the hard way and get some proper data. Also, I discovered yesterday that I'm going to have to port the whole lot to Windows because of image processing dependencies. This might take some time. Hopefully I can eventually close this thread down with some answers rather than questions. Thanks again.
