Description
|
|
===========
|
|
The DolphinVS sample shows an underwater scene of a dolphin swimming, with
|
|
caustic effects on the dolphin and seafloor. The dolphin is animated using
|
|
a technique called "tweening". The underwater effect simply uses fog, and
|
|
the water caustics use an animated set of textures. These effects are
|
|
achieved using vertex shaders

Programming Notes
|
|
=================
|
|
Several things are happening in this sample. First of all is the use of
|
|
vertex shaders. Two vertex shaders are used: one for the dolphin, and one
|
|
for the seafloor. The vertex shaders are assembly instructions which are
|
|
assembled from two files, DolphinTween.vsh and SeaFloor.vsh.
|
|
|
|
The dolphin is tweened (a form of morphing) by passing three versions of
|
|
the dolphin down in multiple vertex streams. The vertex shader takes the
|
|
weighted positions of each mesh and produces and output position. The vertex
|
|
is then lit, gets tex coords computed and gets fog added.
|
|
|
|
The seafloor is handled similiarly, just with no need for tweening. The
|
|
caustic effects are added in a separate alpha-blended pass, using an
|
|
animated set of 32 textures. The texture coordinates for the caustics are
|
|
generated in the vertex shaders, stored as TEXCOORDINDEX stage 1.
|
|
|
|
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:
