To use a texture in your program:

• Create a texture by

– Reserving a name for a texture using glGenTextures().

– How about: Binding its name to the appropriate binding point using glBindTexture().

– Specifying the dimensions and format of the texture using glTexStorage2D() or the appropriate function for the specified texture target.

– Placing data into the texture using glTexSubImage2D(), or the appropriate function for the specified texture target.

• Access the texture in your shader by

– Declaring a uniform sampler in your shader to represent the texture.

– Associating the sampler with the desired texture unit using glUniform1i().
