Question 1

How do I add a 3D model to my Angular app using this template?

Accepted Answer

You'll need to import ThreeJS loaders in an Angular component and set up the scene, camera, and renderer manually. The template provides the base integration, so refer to ThreeJS documentation for loading models like GLTF or OBJ files.

Question 2

What's the performance impact of using ThreeJS with Angular?

Accepted Answer

ThreeJS can be resource-intensive, but the template's OnPush change detection helps mitigate performance hits. For complex scenes, consider additional optimizations like web workers or level-of-detail techniques to maintain smooth rendering.

Question 3

Can I use this template with Angular Universal for server-side rendering?

Accepted Answer

While Angular Universal supports SSR, ThreeJS relies heavily on client-side WebGL and may not render correctly on the server. You'll likely need to conditionally load ThreeJS on the client, which adds complexity to the setup.

Question 4

ng-three-template vs React Three Fiber: which should I choose?

Accepted Answer

If you're committed to Angular, ng-three-template is a practical start, but React Three Fiber has a richer ecosystem and better documentation for 3D in React. Choose based on your team's framework expertise and project requirements.

Question 5

How to set up unit testing with Jest in this template?

Accepted Answer

First, install @angular-builders/jest and configure angular.json to use Jest. Then, write tests for components, mocking ThreeJS objects since they depend on WebGL, which isn't available in Node.js test environments.

Question 6

Is Bootstrap mandatory, or can I switch to another CSS framework?

Accepted Answer

Bootstrap is included but not tightly coupled; you can replace it by removing Bootstrap imports and adding your preferred framework. Update the global SCSS files accordingly, but note that ViewEncapsulation.None may affect styling conflicts.
