## What it is
An open-source Android application for loading, inspecting, and visualizing 3D models, built on a custom OpenGL ES 2.0/3.0 engine. It supports multiple model formats (OBJ, STL, DAE, GLTF, FBX), skeletal animation, VR rendering modes, and interactive tools like wireframe and ray-cast selection.

## Use cases
- view 3d models on android phone
- open gltf or obj files on my device
- inspect 3d model with wireframe and skeleton
- view stl files from 3d printing
- test 3d models in vr cardboard mode
- android app to preview collada dae models
- demo opengl es 3d rendering on android

## When to choose
- you need a free, open-source Android viewer for common 3D formats like OBJ, STL, GLTF, DAE, or FBX
- you want VR/anaglyph stereoscopic viewing of 3D assets on a phone
- you want a reference implementation or demo of an OpenGL ES 3D engine on Android
- you need touch-based inspection tools like wireframe, bounding boxes, and ray-cast selection

## When to avoid
- you need a desktop 3D model editor or full DCC tool like Blender
- you require full FBX animation or rigging support (only static FBX models are supported)
- you need an iOS, web, or cross-platform viewer rather than an Android app
- you need production-grade rendering quality comparable to commercial 3D viewers
