  • 2 Walls to bounce particles in?

    Posted by Mbevilacqua on June 4, 2007 at 8:09 pm

    Is it possible to have more than 1 wall in particular?
    That is a floor, a right wall and a left wall for example in which to bonce particles?

    Thank you!

    Can be done. Just be creative with the way you draw your walls. The trick is in knowing that your wall is maade by a single mask. What that mask shape looks like is off course up to you. It can be as elaborate as you need it to be – again, be creative with your thoughts and you should be able to come up with solution.

    Sounds bit like “Be water my friend” 🙂
    That would imply that you can draw 3D masks right?

    I thought that was not possible… I’ll try!
    Great thank you!

    Duh!?! No. That wasn’t what I was implying. 3D Masks is out of the equation. I can’t give you a definitive way to do what you need because I can’t read your mind to understand exactly what you need.

    If I can take a stab at it, then I’ll say you should draw a big, hard-cornered “U” as a mask shape – it doesn’t have to be a closed mask shape. And it can be an animated mask shape and it can be a single, yet complex mask shape.

    I want to bounce particles on a room with 4 walls, floor and ceiling made of layers arranges in a cube in 3D space.
    3 walls + floor and no ceiling would do though…

    Since this is going on in 3D space I don’t see how a 2D mask can help?
    Maybe I am too short-minded but 3D masks would be the only way out I see…
