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?
You can get the internal array of elements using the ptr() method.
