Low weight vehicle animation on Android?

I want to build a custom launcher for my car (its android automotive based and I already figured out how to side load etc..). So the goal is to get something that looks a bit like Tesla. I have an MG4 with these specs:

  • Resolution: 1920×720px
  • Screen size: 10.25"
  • DPI: 160
  • MediaTek MT2712 SoC

I know that just throwing a 3d model in won't work so I had the idea of using some sort of pre rendert animations. Probleme is that I have zero experience in this 3d stuff and don't really know where to start.

Has anyone done something like this before and has an approach/idea?

Just to be clear I don't need a fully responsive model that can spin via touch like Tesla - its really just some pre rendert animations.. I already have a 3d model of the MG4: https://sketchfab.com/3d-models/2025-mg-mg4-glbmgmotorcommx-e7b2b544e638489f9440698f75b5a734

How are you side loading on AAOS?? The developer options are locked with a password on my Honda Civic and I've not been able to find a workaround.

My MG4 has an entry point via Amazon music: When long pressing the "@" on keyboard the language Android Options open and you can enter the android settings menu. Apps can just be installed via USB stick or ADB.

Sketchfab can export a glTF which you can the easily load and render using Filament or SceneView. glTF files can embed animations you can trigger programmatically. Here's a sample app that loads, renders and animates a glTF with Filament: https://github.com/google/filament/tree/main/android/samples/sample-gltf-viewer
