Should I go on?

Well, I am.

I just posted a big (to me) update to my Shake Tools page on the main ShakeArtist webpage. It's like a baby I thought would never be born.

The DynaCyc toolkit is a spiffy little thing that contains three main tools. The first is called "Forest" - it was originally developed for algorithmically generating dense areas of shrubbery, grass, trees, plants and so on (thus being called "Forest") but I quickly learned that it was also rather handy for replicating a handful of images of people into a large crowd. (That icon is a couple hundred tiny little me-s, wearing dark trenchoats, fedoras and carrying rifles.)

There's a training video for DynaCyc available here.

The other two tools in that toolkit address an issue I used to see a lot when teaching and realized it would be a helpful tool for everyone, not just students. The first one allows you to set a start and end point for an object, indicate an apogee, start time, end time, etc, and have an arbitrary image transformed from the start to the end, arcing in a true parabola (that you can skew to simulate perspective) It seems a lot of people don't realize that freely moving objects ALWAYS travel on a parabolic path (so long as they're in the Earth's gravitational field that is). The last tool, Volley, is what happens if you combine the first two... We can launch hundreds of objects, with a wide variety of adjustable parameters, all driven by some fancy chaos math.

Did I mention that all the tools in the DynaCyc toolkit generate a z-channel when they're done? Oh yes. Yes they do. So it's easy to insert other objects in the midst of them or even to combine multiple instances of those tools in the same scene.

OneLight Plus is another great kit. Using a rendered normals pass (worldspace please! Object/local normals are for game engines), a diffuse pass, and an ambient occlusion pass, this tool is able to simulate additional light sources being cast onto an already rendered object. The video showing how it normals-relighting works is here. Lightmix is a companion tool that makes it easy to tune the apparent focus, light color and intensity of several of these lighting nodes (and can also come in handy for other lighting tweaks using more traditional methods)

I still don't have the training video for this one online yet, and it may be the hardest of any of them to use. If you're a Shake user, though, you can download the uv-retexturing tool itself from this page and get the video when it becomes available. It makes it possible to do fancy things like add damage to a rendered element, track additional details onto digital doubles, completely replace the texture on an existing render... and it works with up to 16 separate textures at once, each up to 8192 x 8192. Imagine having a cg triceratops (like our little icons) that gets beaten up: you can add wounds, dirt, dust, scratches, etc right there in the comp and they'll stay with him as he thrashes and moves.

This last one for today is a tool I wrote specifically as a companion to SynthEyes, but it can be used regardless of the visual effects pipeline it's a part of (as long as they have Shake of course). It applies and removes (in an optically-accurate way) lens distortion on plates. You can remove distortion from a film plate, or apply it to a CG render, or even use it to analyze the plate to determine how much distortion is there. There will be a tutorial for that one eventually as well, but for now you'll just have to wing it if you download the lens distortion tool from here.

On LiveJournal: comment however you like.

It's different there. (I guess it's ok on Xanga too, though that's mainly a mirror not somewhere I really spend any time) Crazy, foul-mouthed or otherwise objectionable comments are generally encouraged or at least accepted, partially because they're not just splashed up on my page when you visit it.

That's one of the things I dislike about MySpace... People posting videos of guys lighting their farts on fire and they can leave them on YOUR page?

No thanks. It's like letting visitors order the PPV East European Ladies BodyBuilding Competition and stealing off with the tv remote then when other people come over to visit I have to explain "Oh, no, I wasn't just watching this... It was somebody else. They did it. Oh, umm, well, I guess, yeah they're my friends but... it was meant to be funny. No, I mean, sure, I admire these women for their dedication to their sport, I'm not making fun... No, when I say 'admire' I mean like, I think it's great that they're doing what they're doing instead of fucking with my tv remote."

but I ended up going in to work today anyway.

I'd agreed without thinking more than "yeah, extra cash would be nice" and forgot what had been looming.

Annoying project. I mean, the spot's going to look cool even if it's a little froufrou. But the details of making it happen are tedious and I agreed to come in and track which I haven't done much of recently and am starting to not miss at all.

So I went in, tracked, found out it wasn't *nearly* as annoying as I'd anticipated... and briefly wandered off into MEL scripting territory to make a button that places arbitrary geometry at the location and orientation of any locators or mesh vertices that you have selected as well as constraining the new geo to the locators in case they were animated. I may change it to orient based on the vertex normal. That might be more handy. It was irrelevant for this purpose though.

That's more interesting and is more helpful for everyone else.

Besides that, I've a thought in my head: My WordPress blog, while inherently "personal" is more along the professional side. Same with my facebook profile... A sizable chunk of my facebook friends are people I know professionally: so glittery graphic "thanks for the add!" and stupid pictures get deleted from my wall. casual banter is fine: but things I wouldn't do or say at work don't happen there either. I've started deleting comments that wouldn't be appropriate to yell out at me at work. If you leave a comment that gets deleted: I'm not mad at you, I'm just not going to embarrass myself on anyone else's behalf.

Myspace is a filthy pit anyway, so I'm not policing it yet. Professional contacts on there are incidental, but I'm probably going to clean that mess up soon as well.
