gMocrengMocren Geant4 has been interfaced to a commercial tool for visualization of voxel data. Free to all Geant4 users. Does not actually function as integral part of the Geant4 visualization system.

Implemented as a G4 example, outputs data in form appropriate for gMocren

Other Voxel Visualization ToolsOther Voxel Visualization Tools Improve how voxel data is handled by the rest of the visualization system. Important as we move from primarily a HEP user base to a base that

includes Medical and Shielding studies. Requires features such as ability to interactively slice the visualization. Do not attempt to reproduce the full functionality of already existing

systems such as gMocren, but rather support and enhance the interfaces to such systems.

Additional Planned Developments (2 of 2)Additional Planned Developments (2 of 2)

Extend functionality current in only some drivers to other drivers: 2D and 3D text Asymmetric scaling Background color Window location Smooth shading Control of auxiliary edges Store camera information from one driver to use in another

Other improvements: Develop Web-based DAWN rendering service Explore dynamic loading of visualization drivers

Area of concern: Complex Boolean shapes not all visualizable beyond RayTracer.

SummarySummary

12 May 2007 11J. Perl Future Plans for Geant4 Visualization

SummarySummary

Seven Visualization Drivers, all well supported

Recent focus on adding interactive features to accomplish what users used to have to do by recoding in C++:

Trajectory Modeling commands Trajectory and Hit Filtering commands Smooth and Rich Trajectory commands Time-Development Animation, etc.

Major new feature coming this year: Visualization of Fields

Major additional focus for this year: Improve tools for visualization of voxel geometries

Additional planned developments: Continue to improve ease of use

Area of concern: Complex Boolean shapes not all visualizable beyond RayTracer
