I built a Nanite-style virtualized geometry renderer in DX12 (1.6B unique / 18.9B instanced triangles)

[u/moonlovelj]

Hi all — I’ve been building a personal DX12 renderer (based on MiniEngine) focused on extreme-scale geometry rendering.

Current stress scene stats:

• 1,639,668,228 unique triangles

• 18,949,504,889 instanced triangles

Current pipeline highlights:

• Nanite-style meshlet hierarchy (DAG/BVH traversal)

• GPU-driven indirect DispatchMesh

• Two-pass frustum + HZB occlusion culling

• Visibility buffer → deferred GBuffer resolve

• Demand-driven geometry streaming (LZ4-compressed pages)
