Interactive High Dynamic Range Volume Visualization

This web page provides supplementary materials for High Dynamic Range Volume Visualization (Vis'05 Paper home page: http://www-users.cs.umn.edu/~xyuan/research/publication/hdrvr.htm).

In order to view the following video sequences, you will need to use an HDR movie player (developed by Drago et al.), which can be downloaded at http://www.mpi-sb.mpg.de/resources/tmo/logmap/HDRMovie.tar.gz or here (ZIP format) or here (tar/gzip format). Here are some instructions on how to play an HDR movie, you can also see these instructions by playing the HDR movie player with no parameter. Note that when you play an HDR video, by default, tone mapping mode is always on, you can adjust the exposure by pressing "-" or "+". When a video sequence is viewed for the first time, it is normal that the animation is not smooth, after several frames, the video would be animated smoothly due to hard drive caching.

Usage: playhdr.exe [command line options] moviefile 
Command line options

                        -a      start in play mode
                    -fps n      target frames per second
Key Strokes and Menus:
                         t      toggle tone mapping
                         g      toggle autoplay
                         m      toggle mouse display
                      h,f1      toggle help screen
                      i,f2      toggle info screen
                     q,esc      quit
               Right arrow      forward one frame
                       -,+      Adjust exposure (shift=smooth)
                         1      first frame

List of video sequences:

Video sequence	Data description	Volume size	Suggest parameters	Sample image
red_star.hdm	Numerical simulation of the deep convection zone in a red gian star. The global alpha is set to 0.005. (200MB)	512x512x512	playhdr.exe -fps 16 -a red_star.hdm The recommended exposure is -3.5.
vort_processing1.hdm	Magnitude of vorticity from a high-resolution simulation of homogenous decaying compressible fluid turbulence at a time when the turbulence is in the process of developing. The global alpha is set to 0.0025. (120MB)	2048x2048x2048	playhdr.exe -fps 16 -a vort_processing1.hdm The exposure should be set to -3.0.
vort_processing2.hdm	Magnitude of vorticity from a high-resolution simulation of homogenous decaying compressible fluid turbulence at a time when the turbulence is in the process of developing. The global alpha is set to 0.005. (615MB)	2048x2048x2048	playhdr.exe -fps 16 -a vort_processing2.hdm The exposure should be set to -6.5.
vort_processing3.hdm	Magnitude of vorticity from a high-resolution simulation of homogenous decaying compressible fluid turbulence at a time when the turbulence is in the process of developing. The global alpha is set to 0.002. (360MB)	2048x2048x2048	playhdr.exe -fps 16 -a vort_processing3.hdm The exposure should be set to -6.5.
vort_end1.hdm	Magnitude of vorticity from a high-resolution simulation of homogenous decaying compressible fluid turbulence at a time when the turbulence is fully developed. The global alpha is set to 0.00125. (360MB)	512x512x512	playhdr.exe -fps 16 -a vort_end1.hdm The recommended exposure is -1.0.
vort_end2.hdm	Magnitude of vorticity from a high-resolution simulation of homogenous decaying compressible fluid turbulence at a time when the turbulence is fully developed. The global alpha is set to 0.00125, but a different transfer function is used. (360MB)	512x512x512	playhdr.exe -fps 16 -a vort_end2.hdm The exposure should be set to -3.0.
twofluid.hdm	Turbulent mixing of air and Sulfur Hexafluoride. The global alpha is set to 0.005. (70MB)	256x512x1024	playhdr.exe -fps 16 -a twofluid.hdm The exposure should be set to -3.0.
