Hi All,
I sat down to make a particle emitter and realized I didn't know how to do a key part of it.
I'd like to draw a sphere and have particles emitted from the surface of it (think like the surface of a star).
The part I don't know how to do is this: how do I find a point on the sphere?
I'd like to randomly pick points on the sphere. With that point, I'll get the normal (I'm also fuzzy on how to do that, since I haven't gotten to that part yet, I don't know if it will be difficult or not). Then I'm have the particle fly out from the surface of the sphere, using the normal as a trajectory. Over time, the particle will fade to nothing.
Thanks in advance!
Steve
