Module uniform_values

Points of interest for seeing uniforms in action:

1. the struct for the data stored in the uniform buffer is defined.
2. the uniform buffer itself is created.
3. the bind group that will bind the uniform buffer and it’s layout are created.
4. the bind group layout is attached to the pipeline layout.
5. the uniform buffer and the bind group are stored alongside the pipeline.
6. an instance of AppState is created. This variable will be modified to change parameters in the shader and modified by app events to preform and save those changes.
7. (7a and 7b) the state variable created at (6) is modified by commands such as pressing the arrow keys or zooming in or out.
8. the contents of the AppState are loaded into the uniform buffer in preparation.
9. the bind group with the uniform buffer is attached to the render pass.

The usage of the uniform buffer within the shader itself is pretty self-explanatory given some understanding of WGSL.
