Hi, I need to do this effect where a wireframe builds itself into existence. Like when Lilu's body is reconstructed in the Fifth Element. For example, say you have a nurbs model of an apple. First I would start with a black screen, then I would have all the horizontal wireframe curves fade in one at a time, going from top to bottom. Then have all the vertical curves fade in one at a time, going from left to right. Finally fade in the textured object. Does that make sense? Any idea how to do that?

side note:

when i was younger i saw that movie, i was just into photoshop at that time, always wondered how they did stuff like that.

what i would do . i havent seen 5 th element in a while but im guessing when the muscle got layed on the bone. that was just one piece of geometry with a projection of a texture. as the object moves the texture is layed out so as it goes along depending on were the object is. so think of it like this. the texture projection is the leangth of the body. while the object is at the toes it is showing that part of the texture down there, as it goes up it shows the texture up near the head. just a projection. also that is compositing work i would think. sorry that is hard to explain with out pics. but also there is shaders that have ramps on them make one part of that shader alpha. so its transparent, animated it up to do what you want. but ...i yiyi i think i tried explaining, but didnt sorry. i would just go to highend, find a shader for what you wanna do . maybe some of that makes sense?

Hmmm, what about PaintFX?

It would be a bit tedious perhaps but here's what you could do (it relies on your model being nurbs though):

1. Duplicate all the isoparms (or the most important ones anyway) into curves using Edit Curves > Duplicate Surface Curves.

2. Apply the PaintFX brush of choice to all the curves (like maybe a black marker brush or something).

3. Now, depending on the effect you want you could either just animate the visibility of each stroke one at a time 'popping' into existance, or you could animate each stroke growing by animating the Max Clip value found under the End Bounds section.

I've done a similar thing before this way, where a 3D airbrush house draws itself into existance and then gets coloured in. It looked really cool because it was 3D and could cast shadows etc.

I think your best bet would be to make seperate renders of the elements you want and then comp them in After Effects or Shake or something. You will get your best results just using masks and some good manipulation. To render this straight out of Maya might take you forever.

But Jozvex, has a really cool idea also.

Thanks for all of your suggestions. Really cool ideas. I'm compiling a list of way to approach this for Monday. Any others would be welcome ;)
