- Wireframe surface outline is being drawn
- Slice rendering direction is changed inside the vessel, to reduce the amount of artifacts seen
- A more interactive transfer function has been added, using pixel shaders
- Animations now work
TODO
Han
Greg
- Implement a more interactive/responsive transfer function implementation using fragment shaders
Paper List
Cylindrical rendering
- Colon Visualization Using Cylindrical Parameterization - Z. Mai, T. Huysmans, and J. Sijbers
- Volumetric Rendering of Cylindrical data
- http://portal.acm.org/citation.cfm?id=99318
- talks about rendering curvilinear surfaces, basically just says to interpolate
Flow Visualization
- Illustrative Stream Surfaces - Silvia Born, Alexander Wiebel, Jan Friedrich, Gerik Scheuermann, and Dirk Bartz
- this paper has amazing illustrative figures of vector fields.
- Evenly Spaced Streamlines for Surfaces: An Image-Based Approach
- Flow Visualization Techniques for CFD Using Volume Rendering https://e-reports-ext.llnl.gov/pdf/238449.pdf
- Nice overview of different flow visualization techniques (streamlines, stream surfaces, etc)
- Flow http://www.zhanpingliu.org/research/flowvis/FlowVis.htm
- overview of many flow visualization techniques - focuses on Line Integral Convolution and extensions of it.
Transfer function
- Semi-Automatic Time-Series Transfer Functions via Temporal Clustering and Sequencing
- An Exploratory Technique for Coherent Visualization of Time-varying Volume Data http://onlinelibrary.wiley.com/doi/10.1111/j.1467-8659.2009.01690.x/abstract
- Importance-driven time-varying data visualization http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4658174
System
- Real-time decompression and visualization of animated volume data
- Texture hardware assisted rendering of time-varying volume data
- A fast volume rendering algorithm for time-varying fields using a time-space partitioning tree.
- Volume Rendering of Abdominal Aortic Aneurysms Roger C. Tam, Christopher G. Healey, Borys Flak, and Peter Cahoon
- http://www.csc.ncsu.edu/faculty/healey/HTML_papers/aneurism/aneurism.html
- old, specific to topic, on whole CT data, not a model
- Computer aided diagnosis for virtual endoscopy Wei Hong
- http://portal.acm.org/citation.cfm?id=1570930&coll=DL&dl=GUIDE&CFID=4717818&CFTOKEN=19743614
- no online copy available
- not specific to blood vessels
- High-Quality Two-Level Volume Rendering of Segmented Data Sets on Consumer Graphics Hardware
- http://portal.acm.org/citation.cfm?id=1081432.1081484&coll=DL&dl=GUIDE&CFID=4717818&CFTOKEN=19743614
- emphasizes implementation of the rendering
Segmentation
- Hybrid Segmentation and Exploration of the Human Lungs
- http://portal.acm.org/citation.cfm?id=1081432.1081468&coll=DL&dl=GUIDE&CFID=4717818&CFTOKEN=19743614
- rendering lungs for virtual endoscopy
- segmentation methods
- touches on blood vessels in lungs - too small/intricate?
- Connectivity-based local adaptive thresholding for carotid artery segmentation using MRA images
- link
- seems relevant, no pdf
Vector field visualization
- Most vector field visualization are textures, “smoke” particles
- mostly seems to apply to fluids passing over solid objects (cars, airplanes)
- Visualization of Vorticity and Vortices in Wall-Bounded Turbulent Flows
- Higher Dimensional Vector Field Visualization: A Survey
- http://cs.swansea.ac.uk/~cszp/files/peng09survey/peng09survey.pdf
- summary of different techniques
- current (2009)
- looked mostly at section 4, 5 & the table at the beginning
