up4 Posted March 5, 2015 Share Posted March 5, 2015 Hi all, I want to have a lens distortion shader that matches the Brown–Conrady / OpenCV / Photoscan camera calibration and lens distortion models. I have looked at the VEX code for the ASAD lens shader. It has 2 outputs: // Outputs export vector P = 0; export vector I = 0; Can anyone elaborate on those? I can't find documentation anywhere and I can't reverse engineer this information from the VEX code. Thanks! Vincent Quote Link to comment Share on other sites More sharing options...
