We are pleased to announce a new VTK.js release, v26!
For this v26 release, we have developed a ton of cool new features to further power-up your web-based visualizations. These features build upon the many capabilities added during our previous VTK.js release and provide a wide range of new capabilities.
Below lists some of the notable changes that landed in v26.
- Cinematic Volume Rendering (release blog post)
- WebGPU: environment mapping and PBR (release blog post)
- Clip closed surface (live example)
- OBB Tree with collision detection (live example)
- 16-bit normalized 3D texture support (thanks to @sedghi!)
- Radon transform blending mode (live example)
- Edge hardware picking (live example)
- vtkSphereWidget (live example)
If you’re looking to upgrade to v26, be aware that there are a few breaking changes from v25. You can see a list of those changes in our breaking changes document.
- SVG Widgets have been fully removed. All SVG examples have been migrated to use an SVG helper.
- ResliceCursorWidget’s API has been updated. Please refer to its documentation and usage for more information.
- Mix-in aware glyph widget
Learning more about VTK.js
If you want to learn more about vtk.js or get help, we have you covered. Below is a list of links to help you navigate vtk.js and its help forums.
If you would like to complement vtk.js’s visualization with analysis or pre-processing of your data, consider itk-wasm. itk-wasm provides simple, efficient support for spatial processing pipelines in WebAssembly. Data can be transferred with the vtk.js ITKHelper.
If you are looking for a server side solution to perform data processing and visualization consider using trame. Trame lets you create your application in plain Python which can then leverage VTK/ParaView with vtk.js. If you want to learn more and explore dozens of examples, go to trame website.
Want to see VTK.js used in a medical viewer? Check out VolView, a drag-and-drop DICOM viewer for the web! Features include cinematic volume rendering, DICOM reading without any external server setup, annotations, and much more.
