Hello:

I wish to randomly and uniformly generate points on a cylinder and a cone (separately). The cylinder is defined by its center, its radius and height. Same specifications for the cone. I am able to get the bounding box for each shape so I was thinking of generating points within the bounding box. However, I'm not sure how to project them onto the cylinder/cone or if this is the best idea.

Any suggestions?

Thanks.

Suppose you have a nice way to move your 2D particles in order to simulate a fluid (like water). Any ideas on how to render it? This is for a 2D game, where the perspective is from the side, like this. The water will be contained in boxes that can be broken in order to let it fall down and interact… >>> More
