The VTK examples have had a significant upgrade:
- WASM has been introduced for the C++ examples. This means that we have a live preview feature in WebAssembly for lots of the C++ examples.
- CI/CD (continuous integration and continuous delivery/deployment) is now running for the C++ examples
For a complex example that loads lots of data from different files, please have a look at PBR_Skybox_Texturing. Feel free to manipulate the image using the sliders and also do rotate/zoom the image. At the bottom of the WASM window you will see all the data files that are loaded.
There is a nightly CI/CD run against the vtk/vtk-examples repository which builds and deploys the web site. This also provides an additional testing of the VTK Master against a broad range of examples. Updates will need to be made to the workflow to add the pipeline to Kitware US runners in order to make it work, please see https://gitlab.kitware.com/vtk/vtk-examples/-/issues/13 for more information.
Not all C++ examples will work with WASM, please see 2_NoWASMIntegration for a list of excluded examples and the reasons why they were excluded.
If you want to contribute an example, please look at 4_ContributingWASM. This is especially important if your example needs data. If your example doesn’t work with WASM then you will need to exclude it and provide a reason as outlined in 2_NoWASMIntegration.
All this work was undertaken by @astucky as part of his internship. The project was originally just to add WASM to the C++ examples.
However he went above and beyond by:
- Writing and compartmentalizing all the WASM scripts. This resulted in minimal changes to the existing scripts
- Clearly documenting reasons why a particular example will not work
- Devising a neat way of ensuring that the WASM examples could access their data
- Setting up CI/CD
We are all grateful for the massive amount of work that Adrien has done, and, to the guidance from @Jules_Bourdais and @ben.boeckel throughout the process. @jaswantp gets special mention for his great help with VTK-WASM, Adrien was really grateful for this help. Also for the sysadmins and others who made this all come together.
Teamwork across many disciplines, works every time!
