The general perspective projection is a map projection of cartography when the earth is photographed from space, the camera records the view as a perspective projection. Description this walkthrough is inspired by an article on creative js the demo shows how to convert 3d points into screen coordinates here we create a very simple. You can think of the projection projection transform (direct3d 9) the projection matrix is typically a scale and perspective projection.
