I've been stuck for a month trying to get gluUnProject working. After my attempts to use gluUnProject failed (as well as attempts to implement gluUnProject functionality manually) I implemented method ...
Matrix.PerspectiveFovLH documentation page says that this method uses the following formula to build a perspective projection matrix. [w, 0, 0, 0] [0, h, 0, 0] [0, 0, zFar/(zFar - zNear), 1] [0, 0, -...
I've read a lot of topics here, on SO, opengl.org etc. Example how gluUnProject should work (from NeHe tutorial): winX = (float)x; winY = (float)viewport - (float)y; glReadPixels( x, int(winY), 1, ...
