Plasma Effects on the ATI Rage128
and Rage128 Pro with Direct3D
|
The R128DX7Plasma sample shows the use of multi-texturing to do plasma effects that used to be done with palette-cycling when 8-bit displays were common. With the Rage128 and Rage128 Pro, this effect can be done at higher color depths for better results. Figure 1 shows R128DX7Plasma in action.

R128DX7Plasma basically works by adding the components of four textures on a polygon, whose texture coordinates are moved in four different directions. You may be able to create your own cool plasmas by choosing four of your own textures and moving them in a different way.
