6In a polygonal representation of space, all visible surfaces are represented as triangles positioned in 3D space based on the eye-position and perspective transformation. Each triangle is associated with specific optical properties such as color and translucency via static or dynamic textures (images or algorithms). The 3D accelerator will then render’ a scene by drawing all visible triangles onto the screen in a specific order (reverse Z-order or back-to-front) drawing pixels onto the screen. The final composite image is then shown as the optical approximation of the 3D space it represents.
