If you plan to make the most out of CS4 Extended, then make sure that you have purchased an upgraded video card that has Open GL capabilities built in. ![]() Since shaders rely on vector technology, the results are instantaneous. So what you are getting is a type of proxy using shaders to simulate the texture capabilities that you have specified for your 3D surface details or video effects. Open GL gives 3D animation software users the capability to see the maximum amount of texturing without actually rendering. Typically, rendering takes an inordinate amount of time and decreases your productivity, which is why Adobe has created CS4 Extended to take advantage of the Open GL if the graphic card has that capability. Rendering is simply the process of producing shading, texturing, reflection, and lighting details to achieve a more photorealistic look. ![]() Programmers for 3D and video programs have worked diligently to design their software so that the user can produce work more effectively without any slowdown, which usually results from rendering.
