I'm working on an animation tool for Autodesk Forge. The animation uses fragProxy getAnimTransform() -> updateAnimTransform() workflow to change object position and sceneUpdated(true) to invalidate the viewer and force visual update.
However,
- sceneUpdated(true) forces all elements in the viewer to be cleared and rendered, and locks the application
- invalidate(false, true, false) forces a progressive render but not clears previous positions
Is there any option to tell what elements need to be cleared and rendered, to reduce animation render flick? What's the best option for an animiation that should operate multiple times per second?
