What are some advanced techniques in WebGL?

Advanced techniques in WebGL include instancing, framebuffers, and shader optimization. Would you like to dive deeper into any of these?

Can you explain instancing and how it improves performance?

Instancing allows you to draw multiple instances of the same object with a single draw call, reducing CPU overhead and improving performance.

What about using framebuffers? How do they work?

Framebuffers are used for off-screen rendering. They allow you to render to a texture instead of directly to the screen, which can be useful for effects like shadows or post-processing.

How can I optimize shaders for better performance?

Optimizing shaders involves minimizing calculations, using simpler data types, and reducing texture lookups. Profiling your shaders can also help identify bottlenecks.
