Title: Catmull-Rom Post by: JosLeys on July 23, 2013, 01:11:36 PM I saw the thread on using CR splines using keyframes, but these splines are easy to program for scenes where the geometry is well-known.
I made an experimental movie where the Eye moves around a closed-loop spline, and the Target is the combination of the tangent to the spline, and an offset in the y direction. I made no attempt to visualize the spline itself. See http://www.josleys.com/show_gallery.php?galid=355 (http://www.josleys.com/show_gallery.php?galid=355).

Make sure you have Quicktime installed. Title: Re: Catmull-Rom Post by: 3dickulus on July 24, 2013, 12:20:10 AM got it, the grand tour of mandel island, nice.
the water looks inviting, how's the fishing?

Somewhere on my to-tinker-with list is passing a boatload of camera keyframe quats in a float texture to the shader and indeed have the shader interpolate. Might Make for a nice demo reel. Would make it harder visualize that path though. Which really helps for those pesky spline over/under shoots on zooms. |
