# t5de-renderer

A new 3D renderer for the IMVU Classic client. Part of [T5DE](https://git.t5de.dev/t5de/t5de); unofficial, not
affiliated with IMVU.

Two programs (`docs/architecture.md`): an adapter, `t5deRenderEngine.dll`, which IMVU Classic loads as a renderer
plugin, and a 64-bit renderer process, `t5de-renderer.exe`, which draws with
[Diligent Engine](https://github.com/DiligentGraphics/DiligentCore). For now the client's own Direct3D renderer still
draws the scene, and the renderer process proves the setup by drawing a small box over it. `docs/interface.md` has
what we know of IMVU's renderer interface.

## Building

Needs Visual Studio Build Tools 2026 (the C++ workload) and CMake 3.28 or newer. One preset per program:

```sh
cmake --workflow --preset adapter    # build/windows-x86/adapter/Release/t5deRenderEngine.dll, and the tests
cmake --workflow --preset renderer   # build/windows-x64/renderer/Release/t5de-renderer.exe
```

The renderer's first configure fetches Diligent Engine (pinned in `renderer/CMakeLists.txt`) and builds it, which
takes a while.

## Trying it

Copy both programs into a T5DE client folder built with the `t5de-renderer` patch, which has the OpenGL setting load
the adapter in place of `glRenderEngine.dll`, then choose OpenGL in Settings > Advanced. The adapter's log is
`%TEMP%\t5de-renderer.log`.
