Hi
I have a osg::matrixd that I use to project point (osg::vect3d) with matrix premult function. At some point, the premult return me a bad result because the matrix determinant is 0. I cannot find a way to find if the determinant is 0. There are no det function for the matrix. Is there a function that compute it? I try to compute it by hand but there, it seems that there are no way to access the matrix internal element.... Anyone have an Idea?
Thank you!
