Question 1

How to load remote 3D models with react-native-gl-model-view?

Accepted Answer

Set the uri property in the model and texture objects to a URL, as shown in the RuntimeAssets.js example. Ensure the server allows CORS if loading from the web, and note that formats must be supported per platform.

Question 2

React Native 3D: gl-model-view vs react-three-fiber?

Accepted Answer

gl-model-view uses native engines for high performance (60fps) but has limited format support and requires manual setup. react-three-fiber is WebGL-based with Three.js, offering more features like GLTF and shaders, but may have performance trade-offs on older devices.

Question 3

Can I use GLTF models with react-native-gl-model-view?

Accepted Answer

No, the library does not support GLTF format. It only supports formats like .OBJ, .3DS, and MD2 as listed, so you'll need to convert models to compatible formats using external tools.

Question 4

How to handle gestures for rotating 3D models in React Native?

Accepted Answer

Use React Native's GestureResponder system with the ModelView component, mapping touch events to rotation props. The GestureControl.js example demonstrates this by updating rotateX and rotateY based on pan gestures.

Question 5

Is react-native-gl-model-view compatible with Expo managed workflow?

Accepted Answer

Likely not, as it requires native linking and manual setup (e.g., editing Podfile for iOS), which Expo managed workflow doesn't support. You might need to eject to the bare workflow or use a different library.

Question 6

What's the best way to animate multiple 3D models at once?

Accepted Answer

Create multiple AnimatedModelView components and synchronize animations using React Native's Animated API. The Multiple.js example shows how to animate several models simultaneously by sharing Animated values across components.
