[Algorithms] splatting

[Paul F. <pf...@at...>]

Charles,

I've been looking at your terrain "splatting" idea recently
(which looks very nice btw), but I've come across some
implementation issues with regard to the PS2:

The second pass where you render the "splats" using their
second gross alpha map is a multi-texture op, how would
you simulate this with multi-pass rendering - surely the
gross alpha requires different texture coords to the splat
texture because the two are different sizes?

Cheers, Paul.
