Hope this helps Yves -------------------------- Cut Here ----------------------- There are several "stereo rendering style" but the most convenient way still the "quad-buffer" stereo rendering style. (see "man stereo") Typical OpenGL applications have to render left and right views in the appropriate left and right framebuffers and lets the video format do the interlaced l/r display. 1. App have to Select the right GLX visual supporting the quad-buffer stereo (see glxinfo, glXChooseVisual) 2. Apps needs to draw your model for each projection view (2 views separated by ~ 6 centimeters). - one for the left eye, drawn in the left frame buffer (see glDrawBuffer), - one for the right eye drawn in the right frame buffer (see glDrawBuffer). 3. Apps or manually Select the according stereo format using (x)setmon or ircombine. As example 1024x768_96s that is going to send left and right buffer alternativelly. 4. you will need then to occude left and right view alternatively by using special devices (sync stereo glasses). If you have more than one video output, then you can also draw each view in separate buffers and send them to separate left and right display devices(polarized display/glasses, HMD). MPK support these stereo styles by doing this job for you (you just need to write the appropriate config file (samples are in /usr/share/Multipipe/src/config) Note also that it can do parallel rendering for left an right view using 2 or more gfx pipes This have to work in 2.4 with volview: 1. copy and edit the MPK config file /usr/share/Multipipe/src/config/1-pipe/1-window.stereo.quad add after mode mono the following lines: mono "/usr/gfx/setmon -n 1024x768_60>" stereo "/usr/gfx/setmon -n 1024x768_96s" 2. I recommend to start your desktop in 1024x768_60 (if needed) using xsetmon or ircombine utility. or test higher frequencies using this xsetmon. It will bring back to the original frequency if problems occurs. and restart the Xserver 3. Launch ./volview -volume -config ./1-window.stereo.quad 4. select "stereo" field in the view menu you will see the turn on between the video format if your display device follows the frequencies generated by the gfx If nothing appears, you need to rlogin from remote workstation, set the DISPLAY env variable to :0.0 and run /usr/gfx/setmon [-n] 60HZ. This means your display is not able to follow high video frequencies. ----------------------------------- Cut here ------------------------------ > > > Massimo Colace - Carlo Bozano wrote: > >> Hi all, >> >> We want implement stereo viewing in our software realized with OpenGL >> Volumizer 2.3 under Qt interface. >> We'll be very grateful if somebody can help us whit any example >> code that explain us how to realize stereo viewing without using MPK >> (OpenGL Multipipe SDK)! >> >> Many thanks, >> >> massicci > Massimo Colace - Carlo Bozano wrote: > Praveen Bhaniramka wrote: > > > Hi again, > > > > > In the "volview" demo the monitor are set automatically. > > > We don't know how to set the monitor for stereo viewing in other simple > > > demos in /usr/share/Volumizer2/src/apps/simple/tmRenderAction under a sgi > > > Octane 2. > > > > In volview, the monitor settings are changed using the setmon command > > specified in the Multipipe SDK config file.

The lookup table is currently implemented using the SGI_texture_color_table extension. There would be multiple potential ways to workaround this problem of multiple lookup tables - 1. Pre-process one of the volumes to apply the lookup table in software before managing the texture. Essentially, you would implement the lookup table in s/w. The texture data would need to be updated everytime you modify the transfer function using setDataPtr(). The pipeline would look like the following - +--------------+ Input luminance data -> | lookup table | -> RGBA data -> Volumizer for +--------------+ rendering This has the disadvantage of using four times the texture memory (since you are using RGBA data instead of simple luminance data), but this might be the easiest to implement. 2. Experiment with other color tables in the imaging pipeline like GL_COLOR_TABLE_SGI, GL_POST_CONVOLUTION_COLOR_TABLE_SGI, GL_POST_COLOR_MATRIX_COLOR_TABLE_SGI to see if they work for you. You will need to manage and implement these lookup tables yourself in your application. This scheme might have some system dependent implications. 3. Implement the lookup tables completely yourself! If you do not enable/bind parameter lookup table in your shader, Volumizer would just ignore the parameter. You can use the SGI_texture_color_table extension in your application to create the multiple lookup tables yourself. In each of the slice callbacks, you will need to download and enable the specific lookup table that you want to use. Good luck!

OpenGL Volumizer is the industry's first commercially available, high-level, immediate-mode volume rendering application programming interface (API) for the energy, medical, and sciences markets. OpenGL Volumizer 2.4 adds new features to allow better scenegraph integration and easier application design. It provides new features for higher quality volume shading, optimizations to the 3D Clip-Texture API, along with other improvements and bug fixes. We would like to thank our customers and software vendors who have provided feedback in helping us prioritize, implement and validate the new 2.4 feature set. OpenGL Volumizer 2.4 can be downloaded for free from SGI at - http://www.sgi.com/products/evaluation/6.5_volumizer_2.4/ OpenGL Volumizer 2.4 provides the application with the following specific features: List of new features/additions ------------------------------ o New XML based Volumizer file interface - XML based Volumizer file loader (libvzxml) - An API to represent collection of volumetric shapes (vzShapeSet) - Higher level interface for rendering shape sets (vzClipRenderAction) o 3D Clip-Texture API - New multi-threading scheme for optimal disk paging of clip-textures - Clip-Texture Render Action optimizations and finer frame rate control - Support for rendering shapes with volume textures using Clip-Texture Render Action - ClipGen3d Optimizations - Multi-threading and Efficient file formats o Volumetric Shaders - Diffuse and Ambient coefficients with vzTMGradientShader o Sample code / Demo applications - Application for rendering and manipulating shape sets (XMLViewer) - Support for run-time plug-in modules in volview - Support for Volumizer XML files in pfVolume - pfViewer (OpenGL Performer 3.0 and above) examples - Sample code documentation with a web (HTML) interface - New sample data sets (CT scan of a Bonsai) o Bug fixes - 3D Clip-Textures: Multipipe Support - 3D Clip-Textures: Accurate geometry ROI mapping - 3D Clip-textures: Multi-threading control for disk paging - TMRenderAction: Accurate geometry ROI mapping with interleaved textures - volview: Slice plane rendering, Volumetric lighting o Documentation - Sample code documentation - Programming guide: New Chapter 7, Updated Chapter 1 - Reference manuals/release notes Changes from the previous release --------------------------------- o All the Volumizer libraries named libVo2*.so are now compiled into a single DSO, libvz.so. The DSOs libVo2.so, libVo2RenderTM.so and libVo2RenderClip.so are not shipped anymore. o New DSOs are provided for the XML file loader. libvzxml.so provides the Volumizer file loader which uses the Apache XML parser library, libvzxerces.so. o The clipTex3d sample application is not shipped any more. A modified version of the sample application is installed in /usr/share/Volumizer2/src/apps/XMLViewer and loads Volumizer data provided in the new XML file format. o The volview variants (volviewTV, volviewMR, volviewClip) are not compiled/shipped anymore. The shipped volview can now load the DSOs from the command line using -module option. The new plug-in modules are installed in /usr/demos/Volumizer2/lib/. o OpenGL Performer based sample code for Performer versions 2.2+ is not shipped. The Performer sample code is installed in /usr/share/Volumizer2/src/lib/Performer/ and uses the XML file interface for loading shape sets. The pfVolume node is compatible with Performer versions 2.5 and above. o Sample Multipipe SDK config files are installed in /usr/demos/Volumizer2/configs instead of /usr/share/Volumizer2/src/apps/volview/configs. o Volumizer sample code documentation is now provided using HTML files. Each sub-directory under /usr/share/Volumizer2/ has an index.html file the documentation for contents of the sub-directory. Please contact me should you require additional information. Thank You!
