Creating compute shader variants has until now been tedious work of hand crafting different kernels for different variations (by combining #pragma kernel and preprocessor defines) and then manually mapping the correct kernels to correct variants at runtime. If this describes a mesh you want to generate, they can do it super fast! You can also use them in the Unity editor, and then save the mesh as an asset file, ready to use in a scene. For now, we just output the results of our compute shader as points. We check if the grass blade should be rendered by doing frustum and distance culling on the position. If any GPU work has been submitted that writes to this buffer, Unity waits for the tasks to complete before it retrieves the requested data, guaranteeing this function returns the most up to date results. Even if you know for sure that the shader does not use resources in its current state because of branching, you must still ensure a resource is bound to it. supportsComputeShaders.
