2014-11-14 10:58:47 -0600 commented question cv::Rodrigues @ opencv3 I do get a cv::Exception but not any text in the console. I also run a debug build but it did not change anything. Since I'm the only one having this problem, i guess its some IDE/linker problem. Went back to 2.4.8 btw. Thanks anyways 2014-11-11 16:01:15 -0600 asked a question cv::Rodrigues @ opencv3 Hi, the example below (with any rotation matrix) works fine in 2.4.8 but throws in 3.0 at cv::Rodrigues. What am i missing? cv::Mat mat = cv::Mat::eye(cv::Size(3,3), CV_32F); mat.at(1,1)*=-1; mat.at(2,2)*=-1; cv::Mat rvec = cv::Mat(1,3,CV_32F); cv::Rodrigues(mat, rvec);  Using Windows 8.1, downloaded binaries, Visual Studio 2012, linked dynamic libs. (Not getting any exception text since its thrown in a dll?!) Thanks for any help.
