RE: [GD-Consoles] Cg, HLSL, ?

[Paul B. <pa...@mi...>]

In Brute Force we have 115 vertex shaders and 85 pixel shaders.
All hand written.  Early on we looked at some sort of high
level shader language (even partially implemented one), but
decided that "we would only have a couple dozen shaders".  We
chose poorly. ;) =20

As others have said, if you are honestly targetting multiple
platforms, then you might not want to look at high level shading
languages.  On the other hand, if you are primarily targeting
one platform, you could tweak and specialize your favorite=20
language for your target - and "make it work" on others. =20
