Texture Sampling
A fragment shader reads image data through a sampler uniform bound to a texture unit, using texture coordinates (usually interpolated UVs) with the GLSL texture() function. The result depends on sampler state, not just the stored texels: filtering, wrapping, and mip selection all shape the returned color.
