Controlling camera angle and animation in embedded visualizations

[T-K-233]

This is a great project!

I want to know if it is possible to control the camera angle and animation sequence, including controlling the playback timing and load different recorded motions, in the embedded visualization after exporting.

I am trying to switch animation based on user input with Javascript in a statically deployed site.

Thanks!

Thanks @T-K-233!!

Controlling camera angle: in case you haven't seen, there are some notes on setting the initial camera pose in the docs here. For programmatically setting it, eg for animations, one option is something like this:

import viser

server = viser.ViserServer()

serializer = server.get_scene_serializer()

# Use (unsupported) private API to set camera position.
from viser._messages import SetCameraLookAtMessage, SetCameraPositionMessage

serializer._insert_message(SetCameraPositionMessage(position=(10.0, 10.0, 10.0)))
serializer._insert_message(SetCameraLookAtMessage(look_at=(0.0, 0.0, 0.0)))

# Etc

Loading different recorded motions: not really unfortunately. The code is designed to be lightweight / hackable though, so you could modify the playback code to support this. Basically all of the logic is in FilePlayback.tsx.
