use img info to generate geo

[Tong Le]

I wanna give the motion to the img which comes from a photo (so is not a perfect img, such it has some noise,etc)

The question is:

I have to generate geos from the pic, so I have to fetch img or pixel color. Then extrude the geo based on the color

Another prob is, each piece should have separate ID, then I can give them a little random secondary motion.

One way I think about is copying box to POPs which will be scat from grid by color, then I can use rand() control the scale of each box

or maybe VOPs? I know VOPs can do it, but I dont know how.

Any idea or suggestion?

Maybe you can try this, it seems to work well.

I had to tweak your image to make it perfectly black&white, to have one pixel per unit, and square.

(Watch out, in my sample your pattern has change a little, so do it clean)

With this solution each pixel is a primitive so it should be easy to make random extrude or whatever you need.

Another solution could be to use trace SOP.

hope to help
