The tomviz project is developing a cross platform, open source application for the processing, visualization, and analysis of 3D tomography data. It is currently at an early stage of development, but is already capable of displaying, visualizing, and interacting with 3D reconstructions of tomographic data. In addition basic alignment and tomographic reconstruction are available, with Python scripts that can be modified in the interface to experiment with different techniques.

The tomviz project is developed principally by Marcus D. Hanwell and Utkarsh Ayachit at Kitware, Inc., and David A. Muller and Robert Hovden at Cornell University under DOE Office of Science contract DE-SC0011385.

We recommend downloading the current stable release but also provide nightly binaries built by our dashboards for Windows, macOS, and Linux.

Windows: Follow the installation instructions, double click on the tomviz icon to launch application. Mac OS X: After downloading tomviz double click to launch installation. After reading the License Agreement, drag the tomviz icon into your Applications directory – or anywhere else you would like to store the application. The first time you open tomviz, you will need to right-click on the application icon and select ‘open’. It will ask you if you are sure you wish to open it, click the ‘open’ button. This is only required the first time launching the application. It can be opened by double clicking all future times. Linux: A Linux binary (dmg) is provided and tomviz can also be built from source. See instructions for building found in the BUILDING.md document.

1. Open a sample dataset by clicking “Sample Menu > Reconstruction ” at the top menubar.
2. Create a 3D volumetric visualization by clicking “Visualization > Volume” at the top menubar.
3. Interact with your volume in the center panel titled “RenderView”.

Start by watching this short video to see tomviz in action.

The tomviz user guide is available for more detailed information to get started.

Our project uses GitHub for code review, please fork the project and make a pull request if you would like us to consider your patch for inclusion.

• On Mac OS X, tomviz built against Qt 5.5 will report several warnings of the form "0x7feeac460480 void QWindowPrivate::setTopLevelScreen(QScreen *, bool)( QScreen(0x7feea9e60200) ): Attempt to set a screen on a child window. (:0, ). These warnings can be ignored.
