WebConstructing GL_PROJECTION matrix for orthographic projection is much simpler than perspective mode. All x e, y e and z e components in eye space are linearly mapped to NDC. We just need to scale a rectangular volume to a cube, then move it to the origin. Let's find out the elements of GL_PROJECTION using linear relationship.
