Animation

December 16th, 2006 — 3:54am

Today I read Animation: can it facilitate? by Tversky, Morrison, and Betrancourt. They argue that animation has little power to “facilitate comprehension, learning, memory, communication and inference” since it violates the Apprehension Principle.

I think they’re right. Comprehension requires time to analyze the graphic and to develop a mental model. An animated graphic is continually presenting new information; interrupting our attempts to understand.

When I’ve used animations or movies in my own learning, I find myself having to compensate by repeating it multiple times or pausing at key frames, etc. In essence, I’m trying to build a static understanding of the animation.

SpaceBalls

December 15th, 2006 — 12:37am

My brother pointed me to this updated SpaceBall product. There was always an old SpaceBall lying around in the lab at BYU. It had some mysterious connector that wouldn’t work with any of the machines in the lab, so it never got used. Are these at all useful for 3D work? It seems like Maya’s interface is pretty simple. Mouse plus Ctrl, Alt, or Shift to choose pan, rotate, or zoom (not necessarily in that order). Does anyone have experience using a SpaceBall?

Obvious sentence of the day

December 14th, 2006 — 6:34pm

Not graphics related at all, but I laughed when I read this (USAToday):

If a Republican replaced any Democrat in the Senate, a 50-50 tie would be broken by Vice President Dick Cheney, giving Republicans the slimmest of majorities. Such a majority wouldn’t only be critical in party-line votes, but also in selecting committee chairmanships and controlling Senate procedures.

The last 50-50 Senate also involved a South Dakotan, former Sen. Tom Daschle, who was head of the Senate Democrats at the time.

South Dakota became a state in…1889. I’d say that the chances that the last 50-50 Senate included a South Dakotan are pretty high.

I’d been thinking about creating a computer graphics blog for awhile. When I saw that Pete Shirley had recently started one, I figured it was the time to jump on the bandwagon.
