Table 1: All the buffers used in the process. N_b, N_e and N_f each denotes the maximum number of blocks, vertices and triangles, respectively, and are assigned 50% of the overall blocks, edges and cells.

buffer	size	type	usage
blocks	Bx × By × Bz	float2	min/max blocks
block buffer	Bx × By × Bz	int	active/inactive (0/1) (shared with edge buffer)
block index buffer	Nb	int	block sequential indices
edge buffer	Nb × 128 × 7	int	edge/isosurface intersections(0/1))
cell buffer	Nb × 128 × 6	int	4-bit value for cells
edge index buffer	Nb × 128 × 7	int	edge indices (incremented by 1 if intersected with the isosurface) (shared with cell index buffer)
cell index buffer	Nb × 128 × 6	int	before serialization: intersections (0/1/2) after serialization: cell indices (shared with edge index buffer)
intersection buffer	Ne	int3	edge indices
triangle buffer	Nf	int3	triangle indices
vertex buffer	Ne	float3	isosurface vertex buffer (shared with intersection buffer)
normal buffer	Ne	float3	isosurface normal vector buffer
index buffer	Nf	int3	isosurface index buffer (shared with triangles buffer)
