Question 1

How does t3d compare to three.js in terms of performance?

Accepted Answer

t3d is optimized for modern real-time workflows with features like clustered lighting and customizable callbacks, often offering better performance for many-light scenes, but three.js has broader compatibility and a larger ecosystem. Benchmarks may vary based on use case, so testing specific scenarios is recommended.

Question 2

How to add post-processing effects in t3d?

Accepted Answer

Use the t3d-effect-composer extension, which provides a composable pipeline for effects like bloom or depth of field. Import it from the addons and integrate it into your rendering loop, as referenced in the extensions list.

Question 3

Can I use three.js models with t3d?

Accepted Answer

Not directly; t3d uses its own format and APIs, so models need conversion or loading through compatible tools. The ecosystem includes extensions like t3d-model-viewer, but interoperability with three.js assets requires manual adaptation.

Question 4

What are the system requirements for running t3d?

Accepted Answer

t3d primarily targets WebGL2 contexts, as shown in the Quick Start with canvas.getContext('webgl2'). It may fall back to WebGL1 in some cases, but optimal performance relies on modern browsers supporting WebGL2 features.

Question 5

How to optimize lighting for a scene with hundreds of lights in t3d?

Accepted Answer

Leverage the built-in clustered lighting system, which efficiently manages many light sources by grouping them spatially. Configure light groups for reusability, as mentioned in the README under key features.

Question 6

Is t3d suitable for building 3D games in the browser?

Accepted Answer

Yes, t3d's performance optimizations and real-time workflow focus make it a good fit for web-based games, especially those requiring fine control over rendering. However, for game-specific features like physics, you'll need additional extensions or libraries.
