Does Rise of Nations use the special effects supported by advanced cards?
We use pixel shaders and hardware-accelerated transform and lighting. • Pixel Shaders Nuclear explosions use a luminance effect to make the whole screen wash to grey. Every “renderstate” has to have a corresponding pixel shader to make this work (one small area, but LOTS of shaders). Boat reflections need pixel shaders to clip at the water line (texkill). • Vertex Shaders Boat reflections use vshaders to put a sine wave on the verts under water, making the reflection look wavy. Some of the nuke effects pieces (mushroom cloud and impact flash) use vertex shaders as well. • Logo The high end GPUs get a dot3 bump map lighting model on the RoN logo in the main menu.
