More 3d Projections

So I thought I would just do 3d projection until I tired of it, then consider it added to my tool kit. I’m taking on my after effects training like grinding in WoW. So to become a better after effects guy I’m going to give myself quests like “create X of Y” and bring them to the blog. To that end I’ve created a few more 3d projections to get a handle on the technique and uploaded them to youtube.

The first I wanted to make a transition that would illustrate that I was making it into 3d. So I took the grid I was using to eyeball the placement and anaimated it on to a duplicate set of surfaces. Then a little transparency strobe, some linear wipes, and a little green tint I think give it a little matrix like feel. Like a computer is building the scene, which it is, only not at all that way. I love how so many movies show computers doing things that computers don’t do. Like coding in a 3d program (I’m looking at you swordfish). And though it is possible to code in almost every damn thing these days, it’s not always the best. Also CSI can eat it for their computer lies.

Next up I thought i would map some text to a 3d surface and try another way of scamming some depth from these shots. So for the text I just copy/pasted the orientation and position properties of a surface to a text layer and pushed the text out a few px. Then moved them around and rotated to fit like they could have been painted. In the future I’ll likely have something animated since it’s as easy as repeating the same process with a nested 2d comp. Now for the doors they are recessed into the building and to get that little recess i would have had to make two walls and a roof for each like a little mini hallway, or done some trickery with a little script. By referencing the layer above I set a few copies of a masked surface to offset by 5 on the z and then just hit command D and made a few till it fit the depth I wanted. You can you that to make some quick 3-d text with depth too if you can’t afford a 3d app or CS5.

Lastly I was noticing something intersting when I had textured planes and a small appature on my camera. By jacking up the blur I found it looked like shooting a miniature with the depth of field being so tight. So I thought I would apply that. I checked out some stock images on Stock Exchange (http://www.sxc.hu/) and broke it down using the regular technique. Then I lined up some text and did a little move from title to title and a little particle action to boot. Everyone likes particles, especially dusty ones. I don’t think theyturned out like I would have hoped but I really havn’t taxed myself to learn more about the cc particle world yet and I likely should. Particles I find look the best when you layer many systems together and blend them, but that takes rendering power that don’thave when I’m already cranking out an extrapolated scene and asking the camera to look cooler.

So that rounds out my 3d projection phase. I think that should be enough to get everyone damn bored with making photos into 3d scenes. I’ve also included the photos below for your reference so you know where they came from if that’s at all interesting to anyone besides other after effects nerds. Also if you would like to have a go at duplicating my stuff let me know and I’ll see if I can guide you along in making this work for you.
