WebA texture is an object that contains one or more arrays of data, with all of the arrays having some dimensionality. The storage for a texture is owned by OpenGL and the GPU, much like they own the storage for buffer objects. Textures can be accessed in a shader, which fetches data from the texture at a specific location within the texture's arrays.
