void gluPerspective(GLdouble fovY, GLdouble aspect, GLdouble zNear, GLdouble zFar); # openGL
void glFrustum(GLdouble left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble near, GLdouble far);
You can convert : left = - fw , right = + fw , bottom = - fh , top = + fh
fH = tan( fovY / 180 * pi ) * zNear / 2; fW = fH * aspect;
fH * 2 / zNear = tan ( fovy / 180*PI ) fovy = atan ( fh * 2 / zNear ) * 180 / PI
