Screenspace Data Example

Hey gamers here is an example showing a geometry shader encoding multiple per-vertex attributes into a grid of screenspace pixel blocks. This exports the data directly without the need for cameras.

This data is captured into a CRT through the use of a grabpass where a different shader can perform arbitrary computations on said data.

Then we read the result of said computations to mesh attributes when actually drawing the mesh.
