Hi, I'm having problems with gluUnProject. I saw other discussions on this message base regarding this function and they did not solve my problem. When I use GLU.gluUnProject I get values that are close, but not quite right. I'm manually keeping track of my model matrix and I replicate the projection matrix manually. (I have also tried setting the projection matrix to identity and manually incorporating a projection matrix into my model matrix, and I ended up with the same results). I tried using the builtin GLU.gluUnProject function and I also implemented my own based on reading that source and reading the C GLU sources and both seemed to give substantially similar results.
So I put together a small demo, trying to keep it as minimal as possible and still get the point across. Either this demo shows a misunderstanding I have of gluUnProject or it shows a bug in the function or opengl projections. Can someone check this over and see if I'm just doing something wrong or if there's a bug that needs to be filed?
