@Nathanius: Sounds good. I forgot about that thread. See you over there when I have something to share relating to that.
In other news:
There's a lot of information in that picture. Let me see if I can break it down at all...
- The yellow line connects each node/keyframe (this is a linear interpretation of the animation).
- The red line is the "out tangent" direction of the node/keyframe.
- The green line is the "in tangent" direction of the node/keyframe.
- The blue squares are the plot of the curve (with unmodified tangents).
- The black line is the plot of the curve, with modified tangents.
By modified tangents, I mean that I used the distance between each pair of nodes to alter the length of the tangent vector. Otherwise the curve looks like the blue curve. (That's why the tangent lines are all different lengths.)
But maybe it doesn't matter, because it's just values it's defining, not the time?
Okay, the orange values are all evenly spaced out on the x/time axis, and the y/value is defined by the value of the curve calculation. (I also scaled the tangents on the modified tangent lines by a factor of 0.5)
(With no tangent modifications:)
