Gray-Scott introduction

After going through a first tour of Vulkan on a simple number-squaring problem, it is time for us to take a step up in complexity and go for a full Gray-Scott reaction simulation.

To this end, a copy of the first (unoptimized) version of the CPU simulation has been copied into the course’s codebase. And throughout most of this chapter, we will see how our current CPU simulation code and GPU infrastructure can be modified in order to get a first GPU simulation.

After that, if time permits, we will also see what kind of changes we can make to this basic GPU program in order to make the simulation more efficient.
