Render and interact with through Blender, o3de, panda3d

Description of proposed feature

STORY: Users can render manim animations with Blender and/or od3e

I think this might increase the utility of Manim for describing complex systems.

Blender:

• is probably faster
• has a physics engine(s) https://docs.blender.org/manual/en/latest/physics/index.html
  • could eventually support NVIDIA physx, which was open sourced in 2022. https://developer.nvidia.com/physx-sdk
  • the soft body FEM Finite Element Method support in PhysX is currently GPU-only FWICS
• pypi: https://pypi.org/project/blender/
• docs: https://docs.blender.org/api/current/
• src: https://github.com/sobotka/blender/tree/master/source/blender/python
• src: https://github.com/sobotka/blender/tree/master/doc/python_api
• https://beautiful-atoms.readthedocs.io/en/latest/ is also built with Blender and Python
• ipyblender: https://github.com/kolibril13/ipyblender-experimental
  • ipyblender wraps the new Python Blender API
  • https://github.com/kolibril13/ipyblender-experimental/blob/main/src/ipyblender_experimental/__init__.py
  • screencast of ipyblender: https://twitter.com/kolibril13/status/1699790198505353259

o3de:

• src: https://github.com/o3de/o3de/
• docs: https://www.docs.o3de.org/docs/
• web: https://o3de.org/
• already supports PhysX
  • https://www.docs.o3de.org/docs/learning-guide/tutorials/physx/
• https://www.docs.o3de.org/docs/api/gems/
  • https://www.docs.o3de.org/docs/api/gems/ros2/ !

physx:

• https://developer.nvidia.com/blog/creating-differentiable-graphics-and-physics-simulation-in-python-with-nvidia-warp/
• https://github.com/petrikvladimir/pyphysx
  • pyrender
  • meshcat
  • https://github.com/bernhard-42/jupyter-cadquery/issues/99 (three.js)

STEM Physics Simulation tools to consider in context to the physics support in Blender:

• https://github.com/topics/finite-element-analysis
• https://github.com/chennachaos/awesome-FEM4CFD
• https://github.com/qd-cae/awesome-CAE
• https://github.com/m2n037/awesome-mecheng#thermal-engineering
• https://github.com/topics/cfd

How can the new feature be used?

• To render Manim animations more quickly and with more detail
• To allow users/clients to pause the simulation / game and VR/AR around within the scene

Maybe once we are able to support multiple render backends cleanly. Though I should add: I am highly sceptical of whether it is worth to write a wrapper just to allow using Mobjects within e.g., blender instead of using something closer to the blender API.

I don't see this happening any time soon, so I'll close this -- but I've tagged it so that we find these resources again once our renderer API is more mature.

Might as well mention some paths to WebAssembly and educational games pygame, pgzero, pygbag + pygame-ce, pygbag + [pygame] + [panda3d || harfang].

Panda3d and Harfang do sufficient FPS 3D with Python and a C++ backend, and so they can be compiled to WebAssembly with emscripten by e.g. pygbag.

There's a note about potential support for pyodide wheels in the pygbag docs. Pyodide powers the Python-in-WASM Jupyter Kernel of JupyterLite and vscode.dev (w/ the pyodide extension and the Python extension) which work without any application deployment, provisioning, or installation on Chromebooks (where containers and now DevTools are blocked) and for a decent calculator you need GeoGebra, Desmos, and/or JupyterLite.
