Description
|
|
===========
|
|
The BumpWaves program demonstrates the bump mapping capabilities of
|
|
Direct3D. Bump mapping is a texture blending technique used to render the
|
|
appearance of rough, bumpy surfaces. This sample renders a waterfront scene
|
|
with only 4 triangles. The waves in the scene are completely fabricated with
|
|
a bumpmap.
|
|
|
|
Note that not all cards support all features for all the various bumpmapping
|
|
techniques (some hardware has no, or limited, bumpmapping support). For more
|
|
information on bumpmapping, refer to the DirectX SDK documentation.
|
|
|
|
This sample also uses a technique called "projected textures", which is a
|
|
texture-coordinate generation technique and is not the focal point of the
|
|
sample. For more information on texture-coordinate generation, refer again
|
|
to the DirectX SDK documentation.

Programming Notes
|
|
=================
|
|
Bumpmapping is an advanced multitexture blending technique that can be used
|
|
to render the appearance of rough, bumpy surfaces. The bump map itself is a
|
|
texture that stores the perturbation data. Bumpmapping requires two
|
|
textures, actually. One is an environment map, which contains the lights
|
|
that you see in the scene. The other is the actual bumpmapping, which
|
|
contain values (stored as du and dv) used to "bump" the environment maps
|
|
texture coordinates. Some bumpmaps also contain luminance values to control
|
|
the "shininess" of a particular texel.
|
|
|
|
In this sample, bumpmapping is used to generate waves in a scene. The
|
|
backdrop is used as a projective texture for the environment map, so it
|
|
reflects in the waves. The waves themselves appear to be generated with lots
|
|
of polygons, but in reality, it's just one large quad.
|
|
|
|
This sample makes use of common DirectX code (consisting of helper functions,
|
|
etc.) that is shared with other samples on the DirectX SDK. All common
|
|
headers and source code can be found in the following directory:
