 Some computer video cards 1. How is a 3D Image Created?
To create a typical 3D images, there are a lot of steps involved. The computer
needs to do the compute vertices, clip edges eliminate hidden surfaces and also
paint textures. Think of the process as drawing up a wire-frame of a scene,
after which the computer fills in the colors and the little pictures that go
into each wire frame. 2. Two Key Operations There are two key operations in a computer related to drawing a 3D image. They are called texture mapping and polygon drawing. Texture mapping is an insanely complicated process because the PC needs to work out the perspective and which surfaces are revealed versus which are hidden from the user. Another important operation is
polygon drawing.
This is a technique used to represent moving objects. What is done is to cover
imaginary wire frames with various polygon shapes so has to give an impression
of a 3D look. 3. Processing Power Now because the graphics operations are so intense, real-time 3D
rendering requires fast CPUs for good performance. Those computers used in
animated movies are stellar in their specs and render graphics at blistering
speeds. Conclusion Whew! Hopefully this article has helped you understand what goes on in a 3D video card. If you're shopping for a 3D video card, try to bear the above points in mind to help you make a better purchase decision.
