This is an example of a 3D Depth Map created by Robert Neuman, the 3D Stereographer on the film. Positive numbers refer to the amount of pixels the image will come out of the screen and negative numbers refer to the amount of pixels the image will go deeper into the screen, creating the 3D depth.

One of the great challenges and one of the great rewards of Finding Nemo is all this floating particulate matter. You know, they put all this flowing particular matter into the original movie to make sure that it felt like the ocean, it didn't feel like a clean aquarium. And so we would have to carefully dial in each one those little particular pieces because if we set the 3D for Bruce the character here, for instance, a lot of that particulate would be too far out into the audience space and so we may kind of crush it, you cull it, you move it and scale it so they're going to work on shot-by-shot basis. And then in a shot like this one of those great Z-axis shots that we were talking about, we actually developed a system that as the particulate specs came closer to camera, they would gradually just dissolve off so that you could still have this feeling of particulate rushing toward us without having to really flattened out the shot, but we didn't want those particulate pieces to just come 80, you know, 90 pixels separated in front of screen, we would actually have them just start to dissolve off once they got to, I think, 20 pixels they must start to dissolve maybe they would be dissolved by 40 pixels converged. You might have gone with 36 pixels, I went with 40 pixels.
And yeah, it's just more of the same -- this was a fun shot to convert because all of those mines are actually a painting, they were all flat in space and so we had to go in and rotoscope out each of those minds and make them place between the space. All right, so guys why don't we gear up that sequence from Nemo and, yeah, hope you enjoy this. Put on your glasses, we'll -- you'll see what I mean by the particulate being both a real boom to volume and space, but also kind of be a problem, so I hope you make good choices that how much particulate to leave in and where to place it [Plays 3D clip from Finding Nemo of exploding mine scene].
See, not a conversion, an actual recreation, we would go back and re-film it. In fact, we re-filmed it at a higher resolution, it was originally 1600 X 900, we rendered at 2K which was many more pixels per frame, which over the course of the movie was 91 trillion something more pixels which should give you a sharper, better picture. So thanks for being part of the support group this morning.
