Question 1

Do Great UI shaders require Three.js or heavy 3D libraries?

Accepted Answer

No. Shaders are written in lightweight raw WebGL or HTML5 Canvas implementations, avoiding hundreds of kilobytes of runtime bundle overhead.

Question 2

How do shaders perform on lower-end mobile devices?

Accepted Answer

Shaders are optimized with low instruction-count GLSL fragment routines and resolution capping for smooth framerates on mobile hardware.
