Create a new soy.meshes class which renders the surface of a liquid (ie, water) and it's depth through volumetric fog using GL_EXT_fog_coord, demonstrated with a small example script.

At minimum color and size properties should be available. A provided material should render as the surface with it's alpha blending properly.

Extensions should be tested using GLEW. Some OpenGL/GLEW functions and enums may need to be added to gl.pxd. Must render on i915, Xorg's free radeon/r200, and proprietary nVidia drivers (ie, no GLSL). Help is available on checking for extension support and testing on different video cards and drivers.

The source can be obtained through

svn co http://svn.pysoy.org/trunk/pysoy

Some inter-module API changes are permissible to implement this.

I claim this task

Here is the code:

And here is the screenshot of example code: http://img166.imageshack.us/my.php?image=asdlq5.png

Code implements the volumentric fog but not the surface texture, which due to alpha, must be rendered after the water contents.

The texture is wrapped now

Ok, I polished things a bit, and the code should satisfy everyone. That's definetly the hardest task I have tried in GHOP, pretty though this work was.

Here is how it looks like: (volumetric fog is calculated for all objects in the scene dynamically): http://img143.imageshack.us/my.php?image=liquidvc7.png

I cannot apply diff of my work, because of "Issue attachment storage quota exceeded.". Code is in the repository

This is exceedingly impressive work. This task was specifically given because this student asked for a challenge.

Two prior SoC projects were to include this as part of the project, and neither finished.
