I am translating world coordinate points to screen space using a 4x4 translation matrix. The matrix contains a perspective transformation. I have used the matrix for a while to draw varius primitives on a very limited platform. Now I want to draw primitives containing bezier curves. My question is: Is it valid to pass bezier curves through a world-to-screen translation matrix if the matrix contains perspective?
