I am a newby researching the best javascript 3D solution to support development of web based 3D (incl VR) technical training. I imagine a combination of scripted animation with audio (voice over) synced to the animation and the ability for the user to interact with the 3D environment (clicking objects to display information etc).
Is there an implementation of a visual timeline editor in A-frame for scripting animation events (timing for object to display, transitions, audio etc)?
