Installation

pip install trame-vtklocal

# We need a VTK that has its wasm counterpart
# This is the first version available with it
# For ParaView (not yet supported), VTK don't need to be installed
pip install "vtk==9.3.20240817.dev0" --extra-index-url https://wheels.vtk.org

Development

Build and install the Vue components

cd vue-components
npm i
npm run build
cd -

Install the library

pip install -e .

Optionally, you can develop with bleeding edge VTK by following these steps

# Compile VTK for wasm32 architecture using emscripten. Build artifacts can be found in dev/vtk/build/wasm
docker run --rm -it -v$PWD:/work kitware/vtk:ci-fedora39-20240731 /bin/bash -c "cd /work && ./utils/build_vtk.sh -u https://gitlab.kitware.com/vtk/vtk.git -b master -t wasm32 -p RelWithDebInfo"

# Compile VTK with python wrappings using system C++ compiler. Build artifacts can be found in dev/vtk/build/py
./utils/build_vtk.sh -u https://gitlab.kitware.com/vtk/vtk.git -b master -t py -p RelWithDebInfo

# Set environment variables
source ./utils/dev_environment.sh -b master -p RelWithDebInfo

Running examples

pip install trame trame-vtklocal trame-vuetify trame-vtk

# We need a VTK that has its wasm counterpart
# This is the first version available with it
# For ParaView (not yet supported), VTK don't need to be installed
pip install "vtk==9.3.20240810.dev0" --extra-index-url https://wheels.vtk.org

# regular trame app
python ./examples/vtk/cone.py

Some example are meant to test and validate WASM rendering. Some will default for remote rendering but if you want to force them to use WASM just run export USE_WASM=1 before executing them.

SharedArrayBuffer

To enable SharedArrayBuffer within trame you can run the following.

export WSLINK_HTTP_HEADERS=./http_headers.json
python ./examples/vtk/cone.py
