Question 1

How to add mouse interaction to curtains.js planes?

Accepted Answer

Use JavaScript event listeners to update shader uniforms based on mouse position; the library's onRender method can incorporate these values for real-time effects, with examples in the documentation for interactivity.

Question 2

Curtains.js vs Three.js for DOM-based WebGL?

Accepted Answer

Curtains.js is better for tightly integrating WebGL with CSS layouts and responsive design, while Three.js offers broader 3D capabilities but requires manual positioning. Choose based on whether DOM alignment or 3D complexity is your priority.

Question 3

How to use curtains.js with React?

Accepted Answer

The official react-curtains package is recommended, as noted in the README; it wraps the core library into React components for easier state management and lifecycle integration in React projects.

Question 4

Can curtains.js handle video textures smoothly?

Accepted Answer

Yes, via the TextureLoader class, it supports video elements as texture sources, but performance depends on video resolution and shader complexity, so optimization may be needed for seamless playback.

Question 5

What are best practices for curtains.js performance?

Accepted Answer

Limit the number of active planes, optimize shader code, and use texture atlases; the library handles some optimizations, but complex scenes require careful resource management to avoid slowdowns.

Question 6

How to create custom shader effects in curtains.js?

Accepted Answer

Define GLSL shaders in script tags or external files, reference them by ID in plane parameters, and update uniforms in the onRender callback; the basic example in the README shows this workflow step-by-step.
