Texture
Noun · Development
Definitions
A bitmap image mapped onto the surface of a 3D model or 2D sprite to give it visual detail — stored in GPU memory and sampled by shaders during rendering using UV coordinates.
In plain English: An image that gets wrapped around a 3D object to give it a realistic surface appearance, like wallpaper on a shape.
Example: "The 4K texture atlas for the terrain alone is 200 MB — we need to stream mipmaps or mobile GPUs will choke."
