WebJun 3, 2013 · Transform your NDC point (x,y,0,1) to view space using the inverse projection matrix. Set the depth to your near plane depth, remembering that typically OpenGL apps uses a negative Z axis for forward view vector, so you probably want -nearZ. Then transform from view to world space using the inverse camera matrix.
