WebAssembly Cone Example

This example aims to provide a base example on how to write a VTK viewer for WebAssembly.

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-cone

Start docker inside that working directory

docker run --rm --entrypoint /bin/bash -v $PWD:/work -it dockcross/web-wasm:20200416-a6b6635

cd /work/build-cone

cmake \
  -G Ninja \
  -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} \
  -DVTK_DIR=/work/build-vtk-wasm \
  -DOPTIMIZE=BEST \
  /work/src/Examples/Emscripten/Cxx/Cone

cmake --build .

Serve and test generated code

cd work/build-cone
python3 -m http.server 8000
