Erik 3c9fc63af7 feat(app): Phase A.2 — wire frustum culling into terrain + static-mesh renderers 
Per-landblock AABB culling against the view frustum. Each loaded
landblock has a 192×192 XY footprint + a Z range derived from the
terrain vertex min/max (padded +50 above / -10 below for entities
on top and basements). One AABB test per landblock per frame;
landblocks fully outside the frustum skip ALL their terrain draws
and entity draws (both opaque and translucent passes).

GpuWorldState gains SetLandblockAabb + LandblockEntries (per-landblock
iteration with AABB data). TerrainRenderer.Draw and
StaticMeshRenderer.Draw both accept an optional FrustumPlanes and
skip culled landblocks. GameWindow.OnRender extracts FrustumPlanes
from camera.View * camera.Projection and passes to both.

Experimental modern open-source Asheron's Call client in C# / .NET 10.

Status: pre-alpha, not playable. Phase 0 only — dat file asset inventory.

Stack: .NET 10, Chorizite.DatReaderWriter for dat parsing. Silk.NET + Avalonia planned for rendering/UI (not yet wired up).

Requires: A retail Asheron's Call install (Turbine/Microsoft property — supply your own). Set ACDREAM_DAT_DIR environment variable to the directory containing client_portal.dat, client_cell_1.dat, client_highres.dat, and client_local_English.dat, or pass it as the first CLI argument.

Layout

  • src/AcDream.Cli/ — console app that dumps asset counts from a dat directory
  • references/ — local read-only reference material (ACE, ACViewer, WorldBuilder, DatReaderWriter, holtburger, retail AC install). Gitignored.

Run

dotnet run --project src/AcDream.Cli -- "C:\path\to\Asheron's Call"

Or set ACDREAM_DAT_DIR and run without args.
