The uniform is updated every frame with the new time, then we redraw. So the loop body is only two lines: This may not look very exciting, but it’s the core of lots of shader animations. For example,this shader animationrenders the current time as a clock. ...

Compile and run vertex and fragment shaders (programs that run on the GPU) to manipulate the vertex and imaged loaded in the previous step. Draw to the screen. The GPU is optimized for these types of operations which enables WebGL programs to perform at a high level. ...
