How do I add bloom to my Three.js scene?

You can use the UnrealBloomPass within an EffectComposer to create high-quality glow effects by configuring the strength, radius, and threshold parameters.

How do I handle window resizing when using post-processing?

When the browser window is resized, you must update both the renderer and the EffectComposer dimensions using the .setSize() method to ensure the effects scale correctly with the viewport.

Can I apply post-processing effects to specific objects only?

Yes, this skill includes patterns for 'Selective Bloom' using Three.js layers and custom render loops to isolate effects to specific meshes while keeping others unaffected.

What is the EffectComposer in Three.js?

The EffectComposer is a class that manages a chain of post-processing passes, allowing you to apply multiple visual effects to a scene after the initial render has occurred.

Does post-processing significantly impact performance?

Every additional pass adds GPU overhead. This skill provides optimized setup patterns and suggests performance-friendly options like FXAA for anti-aliasing to balance quality and speed.
