Question 1

How to set up a basic WebGL project with lightgl.js?

Accepted Answer

Include the lightgl.js script in your HTML, create a GL context with GL.create(), and use utilities like GL.Mesh.cube() and GL.Shader. The README sample code shows a rotating cube demo for quick start.

Question 2

lightgl.js vs Three.js for WebGL development?

Accepted Answer

lightgl.js is lower-level and better for rapid prototyping with OpenGL control, while Three.js offers a full scene graph and is more suited for production apps with advanced features like lighting and animations.

Question 3

Does lightgl.js support texture loading and multitexturing?

Accepted Answer

Yes, it includes a GL.Texture module for handling textures, as demonstrated in the multitexturing example on the GitHub page, allowing for basic texture mapping in prototypes.

Question 4

How to handle animations and updates in lightgl.js?

Accepted Answer

Use gl.onupdate for time-based logic (e.g., angle rotation) and gl.ondraw for rendering, as shown in the sample code, which integrates seamlessly with requestAnimationFrame via gl.animate().

Question 5

Is lightgl.js compatible with modern JavaScript frameworks like React?

Accepted Answer

It's a standalone library, so you can integrate it by managing the WebGL context in framework lifecycle methods, but you may need to handle builds and dependencies manually due to its minimal tooling.

Question 6

How to implement camera controls in lightgl.js?

Accepted Answer

Implement camera controls manually using the matrix stack; the first-person camera example demonstrates this with mouse/keyboard input for transformations like gl.translate() and gl.rotate().
