At a high level, you could think about it as where in your nested loops you put the loop over geometry (say, triangles). A basic rasterizer loops over triangles first, and the inner loop is over pixels. A basic ray tracer loops over pixels, and the inner loop is over triangles (with the BVH acting as a loop accelerator). Just swapping the order of the two loops has significant implications.
