If you store the tangents at these points too, this could work in = reproducing the euler curves. However after converting the keyfranes to = quaternions, the resultant playback could be quite different. The suggestion of Tom is quite appropriate: Supersample the animation = and fit splines through the data. This way you really don't care what = the artists did in creating the animation. I'm doing a similar scheme = here and I can export a character from Maya directly out of the rigged = scene with all it's IK-handles, custom expressions and active = constraints :-) |

Yeah, Tom should know... he's the lead guy now on RAD Game Tool's Granny=20 2 which is all about spline based animation. -- David [Christian Sch=FCler on 4/30/2004 9:39 AM] >>My unenlightened approach would be: >>1) Split all euler based rotation so the x, y, z=20 >>rotation curves have keyframes at the exact same=20 >>positions. >> =20 >> > >If you store the tangents at these points too, this could work in reprod= ucing the euler curves.
