ABSTRACT

The correct way of applying the reflection texture is to project it onto the surface of the polygon. A fixed pipeline supports an automatic application of fog to the objects. It is computed per-vertex from the distance between a vertex and camera/observer. One type of the frequently used objects in games are billboards. The billboard is a polygon which always faces the camera, i.e., orthogonal to the camera’s view direction. The most often-used application of billboards is rendering of particle systems. A particle system is a set of points where each point has its own position, velocity, size, color and other attributes. Bumpmapping is a technique to simulate microrelief of the surface without modifying the actual geometry. Rendering of objects covered with fur is complicated by the fact that fur is really a volumetric phenomena. It is the volume of space filled with densely packed fur hairs.
