David Lu is cooking up something new. A while ago he produced a beautiful and elegant iPhone / iPod Touch app called vellum, and now he’s working on a new version for the iPad. I’m helping beta test some of his early prototypes, and I just have to say I’m very excited about where the app is headed.

This is my first sketch with it.

A sketch I did this weekend. Been a long time since I’ve drawn anything.

Also I need a new scanner. The SANE drivers for my old CanoScan LiDE 30 don’t work quite right in Lion.

I spent some time earlier in the week refining the drawing algorithm even further, focusing on color palette selection and line weight distribution. I think I’m getting closer to something the produces pretty consistent results.

My next step — or perhaps experiment — will be to create some color palettes based on actual color fields that I produce using real paint or some other image source. I want finer control and intention over the possible color palettes, and while toxiclib’s color utilities are pretty amazing, I’m finding that the ColorRange constraints produce less-than-desirable results most of the time (too much or too little saturation and brightness at undesirable moments).

Here’s a demo of the Processing app so you can see the renders in realtime:

And here is some more hi-res output from the app:

Thing learned tonight: the quality of your materials matters. Period.

This is from last night’s life drawing session at The Stables. It was a 1.5 hour pose. I feel like I did a pretty good job of hitting the likeness, but I was really pissed at the quality of my charcoal and paper. Looks like it’s time to ditch the crap I’ve been using.
