Thanks for the reply.
Sorry about the vagueness - I was thinking more on the lines of using on-the-fly to create a sort of "3D paint" world. I'm tracking a second light for this world, which the user holds in his/her hand, and theoretically a stream of paint appears wherever the user moves the light.
My problem now is deciding on the implementation. I thought about creating small "paint pellet" spheres where the hand is every second, but I was concerned about clogging vizard with too many objects and polygons. Instead, I was wondering if I could use on-the-fly to create a kind of "paint tube" object. Theoretically, on-the-fly will constantly update the shape of this tube compared to the user's hand movements.
Is that possible?
