Re: [Algorithms] casting shadows on semi-transparent objects

or course, on the PC side you can also use WGL_ARB_multisample with
GL_SAMPLE_ALPHA_TO_COVERAGE_ARB for order independant transparency.

One of the shrek programmers posted a fantastically awesome fix for this
- just use stippled alpha with a checkerboard stipple pattern.

It's only reasonable on televisions (the stipple pattern gets lost in
the noise and you can't see it) and if you can live with the restriction
of things with exactly 50% alpha, and with the restriction that no
stippled things can overlap in screenspace.

Shrek used it on their water plane - the shadows appeared on the water
surface itself and on the floor below the water.  Even with component
inputs I couldn't see any artifacts.
