Image Description, by
This is an image of a terrain engine\ocean water system I've been
working on recently. The images show the ocean water shader in action,
with a randomly generated island in the background. This is an update to
one of the demos included with the book Real-Time Terrain Engines using
C++ and DirectX 9 from Charles River Media. I'll be continuing to
support and extend the sample engine included with the book on my web
site, www.mightystudios.com. The
updated ocean water shader shown can be downloaded from the site, but
the source code included with the book is required to build the complete
demo.
Terrain Engine Features:
Roam, Chunked and Tiled geometry methods
Quad-Tree visibility culling
Random terrain geometry and texture generation
Animated cloud cover
Atmospheric light-scattering illumination model
Ocean Water Features:
Animated, procedural geometry using FFTs to generate wave motion
Can be tiled infinitely in all directions
All visual aspects (water color, specular strength) controlled by a
single gradient texture.
Both systems are written exclusively using HLSL vertex & pixel shaders
for DirectX 9
