Just a quick quesiton. I have an IPO curve with tons of vertices (e.g. imported from a BVH file). Is there a way to let Blender “decimate” the curve, keeping only the most effective 10 or 20 vertices? Doing this by hand is really tedious!
I don’t think there’s a literal decimator though there is join > selected doubles but not sure how it works. You can have multiple selected curve points at once using shift and click after doing edit selected on the curve.
I can assume that you imported the BVH using the script bundled with Blender. Scripts window under “Import” and select “Motion Capture (*.bvh)”
If so you should have a bunch of empties and IPO curves for these empties.
Now in your scripts window under “Animation” select the “Empties to Armature” script to convert these empties into an armature. One of the settings in this script window is “Frame Decimation” which is the number of frames to skip between keys.
