Version 8.0 of the Visualization Toolkit Assigns New Code Standard

Share Article

Kitware disseminates version 8.0 of the Visualization Toolkit, which prioritizes C++11 and data processing for high-performance computing.

VTK now officially supports different aspects of C++11 such as default constructors, static assertion, non-static data members and enumeration declaration.

Kitware passed another turning point for the Visualization Toolkit (VTK) with the release of version 8.0. The release became the first to benefit from C++11 compliant compilers. VTK now officially supports different aspects of C++11 such as default constructors, static assertion, non-static data members and enumeration declaration.

“The new features in C++11 allow developers to be more productive and eliminate common sources of bugs,” said Dave DeMarle, a principal engineer at Kitware and a developer of VTK. “Now that VTK enforces the availability of a C++11 compiler, developers can rely on capabilities without maintaining awkward workarounds.”

For high-performance computing, the 8.0 release annexed the VTK-m framework of tools. These tools include new filters that process data. Kitware uploaded the filters to the Accelerators/Vtkm folder in the VTK repository.

Outside of VTK-m, the release merged algorithms that process points and geometries. One algorithm (vtkLagrangianParticleTracker) visualizes particles as they move through simulations, and another algorithm (vtkCookieCutter) precisely cuts a two-dimensional (2D) geometric surface with a separate 2D surface that acts as a stencil. Additional algorithms (vtkDensifyPointCloudFilter and vtkUnsignedDistance) operate on point clouds. The release also augmented existing algorithms in VTK. The algorithm for dual depth peeling, for example, developed the ability to render volumes.

In addition, the release added the QVTKOpenGLWidget class, which provides a robust integration of VTK and Qt 5. The release also improved the OpenVR module, which pairs data with Oculus Rift and HTC Vive.

“The transitions to Qt 5, C++11 and Python 3 give users, developers and packagers a great deal of capability and flexibility in VTK-enabled applications,” DeMarle said.

VTK is an open-source software platform that manipulates and displays two-, three- and four-dimensional data. The VTK download page contains files for version 8.0. For more points of the release, please read the Kitware blog. For assistance with VTK, please contact kitware(at)kitware(dot)com.
