Hi Matthew,

this is one of most interesting NeHe lessons,
thanks for bringing it to thinBASIC!

Interesting is to watch how is it casted to for example on:
[code=thinbasic]
tbgl_Torus 2.5,3.5
[/code]

... or models
If you add blending it looks like from glass...
I think TopDown will use fragments of this lesson


Bye

Hi,

I like this lesson a lot, here is little script using the spherical mapping shown in Mathews code.
It is quick try to create water like surface. Although it does not look like real water, I think it is better than just wawing surface with static texture. It handles up to 3 wave generators at time, more is possible, but quite slow.

Just click-click-click


Bye,
Petr

I've just tried your programme and it looked like a very realistic water effect.
