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:


tbgl_Torus 2.5,3.5


... 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. :)

Looks great here.

HE he he he, now I understand the just click click click line :)

The first time I ran it and didn't read the instructions, I was like, well nice, but not much like water.

Then I ran it again and read the instructions and clicked, clicked, clicked. Amazing.

There is a downside too all of these marvels that keep appearing as scripts in these forums, my c++ studies have pretty much come to a halt. What is bad is thinBasic is only available on Windows systems. And when I eventually get a smarthphone I will be going nuts not having its niceness to program with :)
