Morph targets are sets of geometry vertices positions for automatic interpolation between them. You can change geometry appearance in real time, using different vertices positions written in morphTargetInfluences[0], morphTargetInfluences[1], morphTargetInfluences[nSet]
. You can mix many appearances (morphTargetInfluences) of geometry at the same time. Best way is JSONLoader format, wchich you can export from 3DSMax for example: frame0 as morphTargetInfluences[0]
, frame1 as morphTargetInfluences[1]
, ect.
The original geometry vertices are untouched, which you can check using geometry.computeBoundingBox();
geometry.boundingBox();
