# osim-magnum-viewer

Read-only OpenSim viewer built with OpenSim, Magnum, SDL2, and ImGui.

## Build

```bash
git submodule update --init --recursive
cmake -S . -B build -DOpenSim_DIR=/home/crosstyan/Code/opensim-core-build/install/lib/cmake/OpenSim
cmake --build build -j
```

## Run

```bash
./build/bin/osim-magnum-viewer /path/to/model.osim /path/to/motion.mot
```

Optional flags:

```bash
./build/bin/osim-magnum-viewer model.osim motion.mot --geometry-dir /path/to/Geometry --speed 0.5 --start-paused
```

The repo vendors a `Geometry/` directory and searches it automatically at runtime.

Sample run:

```bash
./build/bin/osim-magnum-viewer \
  /home/crosstyan/Code/opensim-core/OpenSim/Moco/Test/walk_gait1018_subject01.osim \
  /home/crosstyan/Code/opensim-core/OpenSim/Moco/Test/walk_gait1018_state_reference.mot
