flag-effect?

[martinzwigl]

Hi folks.

I want to build a surface (rect) which is moving like a flag. now i have seen a example solving this problem with GL_QUADS. wouldn't it be easier to do it with a Bezier Curve and with what rule would i move the control point(s).

thanks for your help,
martin

Regardless of how you represent the flags surface (bezier surface or quad mesh) the easy way to make it move is to use some sine functions. Think of a sine curve moving along the length of the flag. The hardcore way to do it is of course to write a cloth sim and use that, but that might be a little overkill for a flag =)
