Verified the real GfxObj data shape against DatReaderWriter's generated
types and WorldBuilder's ObjectMeshManager. Three corrections:
- GfxObj.Surfaces is a list and Polygon.PosSurface indexes into it;
multiple surfaces per GfxObj are the norm. GfxObjMesh.Build now
returns IReadOnlyList<GfxObjSubMesh> — one sub-mesh per referenced
surface. StaticMeshRenderer draws entities by grouping entities by
GfxObj and then by sub-mesh within each GfxObj. Matches the approach
WorldBuilder takes.
- LandBlockInfo has both Objects (Stabs — small decorations, rocks,
trees) AND Buildings (BuildingInfo). LandblockLoader loads both
lists and maps them uniformly to WorldEntity since both types share
the Frame shape.
- Stab.Frame and BuildingInfo.Frame carry position+orientation only,
no scale component. WorldEntity.Scale dropped. WorldEntitySnapshot
loses its Scale field too. Phase 3+ can add it back if needed.
Closes the one open design question flagged in the original doc.

Locks the design decisions from brainstorming: full scope (geometry +
textures + 3x3 neighbor grid), dual cameras (orbit default + FlyCamera
toggled by F), minimal plugin API growth (IGameState.Entities snapshot
+ IEvents.EntitySpawned). BCnEncoder.Net handles DXT/BCn decoding,
matching WorldBuilder's approach.
Adds three new namespaces under AcDream.Core (World, Meshing, Textures)
and three new rendering components under AcDream.App (StaticMeshRenderer,
TextureCache, FlyCamera + ICamera). Entities are deduplicated by
GfxObj id at the GPU layer; textures dedup by Surface id. Plugins
get immutable snapshots, not live references.
Rough 18-task sequence captured. Full bite-sized plan comes next via
