# WebAssembly ConeFullScreen Example
This example aims to provide a base example on how to write a VTK viewer for
WebAssembly while adding callback to monitor browser size to adjust the rendering canvas.
## Compiling example against VTK
We assume inside the `work/` directory to find the source of VTK under `src/`
and its build tree under `build-vtk-wasm`.
If VTK is not built yet, please follow the guide `../README.md`.
Let's create the build directory for our example
```
mkdir -p work/build-conefullscreen
```
Start docker inside that working directory
```
docker run --rm --entrypoint /bin/bash -v $PWD:/work -p 8000:8000 -it dockcross/web-wasm:20230222-162287d
cd /work/build-conefullscreen
cmake \
-G Ninja \
-DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} \
-DVTK_DIR=/work/build-vtk-wasm \
/work/src/Examples/Emscripten/Cxx/ConeFullScreen
cmake --build .
```
## Serve and test generated code
```
cd work/build-conefullscreen
python3 -m http.server 8000
```
