Sinus

Zelos:
I have a question on sinus curves, its easy to make one if it goes along the X axel, but how do you do to calculate X/Y coordinate if the line the sinus have its center on have an angel of Z°?

Griz:

well the Y value isn't going to change.
(assuming the x axis is from left to right, the Y up to down, and Z front to back?]
so wouldn't the new X value just be X*sin(Zangle)?
or perhaps I misunderstand your question.

check these pages out:

I use these pages a lot for help in understanding isosurfaces ...
so perhaps you can find something to help you visualize such functions
in 3D and how they work.

if not ...
well then perhaps I will get you hooked on raytracing and programming
the amazing program POVray. ;)

it's Freeware!!!
information needs to be free!

Numsgil:
My sinus's are clogged right now.

But I guess that's sort of off topic isn't it.

That'll be the Asian bird flu  :rolleyes:

Zelos:
I nwant it to be like this, it might be ugly but I hope it shows what I want to show.
