All 5 phases of the open-source Decal rebuild: Phase 1: 14 decompiled .NET projects (Interop.*, Adapter, FileService, DecalUtil) Phase 2: 10 native DLLs rewritten as C# COM servers with matching GUIDs - DecalDat, DHS, SpellFilter, DecalInput, DecalNet, DecalFilters - Decal.Core, DecalControls, DecalRender, D3DService Phase 3: C++ shims for Inject.DLL (D3D9 hooking) and LauncherHook.DLL Phase 4: DenAgent WinForms tray application Phase 5: WiX installer and build script 25 C# projects building with 0 errors. Native C++ projects require VS 2022 + Windows SDK (x86). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# D3DService.DLL
|
|
|
|
## Origin
|
|
**Entirely new** — no corresponding code in the old source tree.
|
|
Provides a higher-level 3D graphics API that plugins can use to render 3D objects
|
|
in the game world (meshes, 3D text, transformed geometry).
|
|
|
|
## Binary Facts
|
|
- Size: **262 KB** (the largest of the new native modules)
|
|
- Type: COM in-process server (DLL)
|
|
- Standard 4 COM exports: `DllCanUnloadNow`, `DllGetClassObject`, `DllRegisterServer`, `DllUnregisterServer`
|
|
|
|
## Key Imports
|
|
| DLL | Functions |
|
|
|-----|-----------|
|
|
| **Inject.DLL** | `BeginSceneO`, `EndSceneO` |
|
|
| **d3dx9_30.dll** | `D3DXCreateRenderToSurface`, `D3DXLoadMeshFromXResource`, `D3DXLoadMeshFromXW`, `D3DXCreateTextW`, `D3DXMatrixTranslation`, `D3DXMatrixRotationY`, and others |
|
|
|
|
## What It Does
|
|
- Loads `.x` mesh files (from resources or from disk)
|
|
- Creates 3D text geometry
|
|
- Performs matrix transforms (translation, rotation)
|
|
- Renders to off-screen surfaces
|
|
- Essentially a "3D drawing toolkit" layered on top of Inject's scene hooks
|
|
|
|
## Reconstruction Notes
|
|
- **LOOK AT:** `Managed/Decal.Interop.D3DService/` for the COM interface definitions
|
|
this DLL must implement. That directory contains **8 decompiled C# files**.
|
|
- There is **no old source** to reference. This must be reimplemented from:
|
|
1. The COM interfaces defined in the interop assembly
|
|
2. Knowledge of the D3DX9 API calls it makes
|
|
3. Understanding of how `BeginSceneO`/`EndSceneO` work (see `Native/Inject/`)
|
|
- This is the most complex new module to reconstruct due to its size and the
|
|
lack of any prior source code.
