WebGL Textures: From Image File to GPU Pixels
WebGL textures are images uploaded to the GPU for fast access when "painting" 3D models. They're used to apply detailed surfaces like brick patterns. The footgun: images must be CORS-approved, and non-power-of-two dimensions break mipmapping in WebGL1.
A WebGL texture is an image buffer on the GPU, giving shaders high-speed access to pixel data. It's like applying a decal to a 3D model to add rich detail. This is key for rendering realistic surfaces like wood grain or brick. The footgun: texture loading is subject to cross-domain CORS policies, and in WebGL1, images with non-power-of-two dimensions (like 300x500) can't use mipmaps and have restricted wrapping modes.
