+## Showcase: native_ts_graphics
+
+**[native_ts_graphics](https://github.com/ASDAlexander77/native_ts_graphics)** is a set of real-time 3D graphics samples written in TypeScript and compiled to native code with tslang.
+
+- **25 samples**, TypeScript ports of NVIDIA's Donut samples on the [Donut](https://github.com/NVIDIA-RTX/Donut) rendering framework, on **Direct3D 12** and **Vulkan**: from `basic_triangle` and `deferred_shading` to ray tracing (`rt_reflections`, `rt_shadows`, `rt_particles`), meshlets, compute n-body, order-independent transparency, terrain tessellation, variable-rate shading and work graphs
+- **Mixed C++/TypeScript** through CMake: `.ts` files are a first-class CMake language (`TSLANG`), compiled with `tslang --emit=obj` and linked with the C++ code, with incremental rebuilds
+- Runs on **Windows** and **Android** (Vulkan, `arm64-v8a` and `x86_64`): the Vulkan samples are packaged as APKs, with a script that builds the samples, starts an emulator and tests them
+- Choose the memory model at configure time: `-DTSLANG_MEMORY_MODEL=gc|rc|none`
+
+It is a good place to see how TypeScript code drives a native C++ framework: the samples call Donut through a C interop layer (`donut_interop.d.ts`) wrapped in TypeScript classes.
