Objective
Pursure volume rendering that is suitable for real-time and interactive virtual colonoscopy display.
The objective of this project is to:
- Examine internal volume rendering (open source) availabel in Slicer
- Provide external volume rendering (closed source) for virtual colonoscopy
- Compare the performance of these volume rendering routines.
- Compare the advantages and disadbantages of these volume rendering routines
Approach, Plan
Several virtual colonoscopy datasets will be rendered by use of the below volume rendering routines.
- VTK GPU Raycasting in slicer 3.6 (GLSL)
- Microsoft research (MSR) volume rendering (CUDA, closed source)
Their performance will be compared based on various metrics.
Progress
The two volume rendering routines are installed on a single computer (single CUDA-based GPU) for rendering the virtual colonoscopy datasets as well as for performance comparison purposes.
Delivery Mechanism
A table that shows a comparison of the above two rendering engines in terms of
- rendering performance and
- advantages and disadvantages in rendering virtual colonoscopy datasets in clinical settings
will be delivered.
