- Csaba Pinter (Queen's)
- Steve Pieper (Isomics)
- Jean-Christophe Fillion-Robin (Kitware)
- Review the newly exposed GLSL hooks in VTK as a mechanism to add features to Slicer's Volume Rendering
- Possible features to explore
- Optimized performance/quality for multiple overlapping volumes
- Custom clipping or other rendering features
- Adding nonlinear deformations
- Review what's new since we discussed this last year
- New VTK version and classes
- New Slicer GUI
- Other GLSL examples that we can draw from
- IBIS / PRISM
- STEP
- Document existing functionality in the VTK wiki on this page and identify potential builtin variables and functions that could be added to facilitate the creation of new volumetric effects.
- Replicate the examples presented in the PRISM paper using the improved VTK mapper.
- Replicate the US heart rendering of Philips machine with data from Matt Joley.
- Provided a proof of concept (python script) for dynamic shader editing in Slicer (see image, video and link to script below)
- Started documenting the new volume rendering functionality of VTK here
- Suggested improvements:
- VTK: expose interface for setting custom uniform variables in vtkGPUOpenGLRaycastMapper
- Slicer: Build an interface to interactively edit shader code, visualize the complete shader and display shader compilation errors.
