Smooth Flame Motion

Here's a better example of the smooth motion interpolation just released with FLAM3 2.7b7.

Compare smooth and linear interpolation. Both of these animations use the same keyframes. In the linear one there are two angles or jolts in the motion, one at 2 seconds in and the other at 4, but in the smooth one there are none.

They were rendered with this frames 30 to 120 of this sequence with this command:

env begin=30 end=120 qs=0.1 ss=0.25 flam3-animate < cr3.flam3

You can set the interpolation from linear and angular to smooth Catmull-Rom splines on any keyframe. It then applies to the interpolation from that flame to the next one. You cannot apply smooth interpolation to the first or last keyframes of a sequence.

Thanks to Chris Ursitti for the genome used as the basis for this example. Posted by spot at April 29, 2006 03:15 PM
