# retroDE_ps2 — Ch338 board acceptance: CROSS-BATCH Z ordering for >FIFO_DEPTH scenes.
|
|
#
|
|
# A NEAR (RED) and a FAR (BLUE) triangle occupy the SAME tile (tile 5 = the CENTER 16x16 block) but
|
|
# are SPLIT across FIFO batches. ZBUF clear=0x4000, TEST=GEQUAL (higher Z = nearer wins). With
|
|
# persistent cross-batch Z the NEAR (RED) triangle wins the overlap in BOTH orderings:
|
|
# stage 1 NEAR_FIRST (near RED batch0, far BLUE batch1): CENTER block must be RED (far Z-rejected)
|
|
# stage 2 FAR_FIRST (far BLUE batch0, near RED batch1): CENTER block must be RED (near wins)
|
|
# The CENTER staying RED in BOTH proves identical depth ordering regardless of the batch boundary.
|
|
# (Pre-Ch338 per-batch Z would show the CENTER BLUE in stage 1 — the later batch overwriting the
|
|
# nearer earlier prim.) Surrounding tiles: stage1 top-left RED / bottom rows BLUE; stage2 reversed.
