Gint GPU Culling

Screen-space vertex culling Sub-pixel discard · gap-free Visvalingam–Whyatt rank 64-bit Morton bit-mask Zero CPU · Zero network on zoom
Drag to zoom. The GPU vertex shader keeps every vertex whose detail is ≥ 1 pixel and auto-discards the sub-pixel rest — on the GPU, zero CPU, zero extra bytes.
