WebIf you e.g. work on a one-dimensional array, like we do in this chapter, you only have to specify the x dimension for both. As an example: If we dispatch a work group count of [64, 1, 1] with a compute shader local size of [32, 32, ,1], our compute shader will be invoked 64 x 32 x 32 = 65,536 times.
