With the advent of the nFiniteFX programmable architecture and DirectX 8, developers can now specify personalized combinations of graphics operations and create their own custom effects. Games and other graphics-intensive applications offer more exciting and stylized visual effects. Two patented architectural advancements enable the nfiniteFX engine's programmability and its multitude of effects: Vertex Shaders and Pixel Shaders.


Vertex Shaders inject personality into characters and environments. Motion invades the entire scene, not just the focal points. The vertex processing capabilities allow characters to move and show facial emotion, materials to stretch, and the scene to come alive. By customizing the skinning and motion effects, developers can create a personality, intensifying the impact of the visualization or animation.


Pixel Shaders create ambiance with materials and surfaces that mimic reality. A virtually infinite number of material effects replace the artificial, computerized look with high-impact organic surfaces. Characters now have facial hair and blemishes, golf balls have dimples, a red chair gains a subtle leather look, and wood exhibits texture and grain. By altering the lighting and surface effects, artists are able to manipulate colors, textures, or shapes and generate complex, realistic scenes.
