vprender version 2.0beta -------------------------- Phil Lacroute volpack@graphics.stanford.edu 16 December 1994 1. Introduction --------------- Vprender is a demonstration volume rendering application based on the Tcl scripting language, the Tk graphical user interface toolkit, and the VolPack volume rendering library. It can also be used as a Tcl package that can be combined with other packages. This release of vprender is completely different from earlier versions. It now contains nearly the full functionality of VolPack and includes a new, streamlined demo script. The old graphical interface ("viewer") is still available with some enhancements. 2. Installation --------------- Vprender uses the following libraries: VolPack version 1.0beta3, available from ftp://graphics.stanford.edu/pub/volpack Tcl version 7.3 and Tk version 3.6, available from ftp://ftp.cs.berkeley.edu/ucb/tcl/tcl7.3.tar.Z ftp://ftp.cs.berkeley.edu/ucb/tcl/tk3.6.tar.Z (vprender has not been tested with Tk4.0 yet) Itcl version 1.5 (required for demos and much of the provided Tcl routines, but optional otherwise), available from ftp://ftp.aud.alcatel.com:/tcl/extensions/itcl-1.5.tar.gz Photo widget extension to Tcl/Tk (optional), available from ftp://ftp.aud.alcatel.com:/tcl/extensions/photo-2.4.tar.gz (Tcl and Tk are available here also) tkGLX extension to Tcl/Tk (optional, for SGI only), available from ftp://ftp.aud.alcatel.com:/tcl/extensions/tkGLXwin-1.3.2.tar.gz Sam Leffler's TIFF library (optional), available from ftp://sgi.com/graphics/tiff/v3.0.tar.Z The IP addresses for the above machines are: graphics.stanford.edu 36.22.0.39 ftp.cs.berkeley.edu 128.32.35.31 ftp.aud.alcatel.com 1***.***.191.10 sgi.com 192.48.153.1 Once you have all of these libraries installed, do the following: A. Type "./configure" in this directory. This will run a shell script that determines the features of your operating system and then automatically chooses configuration constants for vprender. If configure prints a message like: *** cannot find (edit config.paths) *** then edit the file config.paths, delete the file config.cache, and rerun configure. Config.paths contains search paths for the required and optional packages. If you still have trouble, look at the file config.log for detailed error messages from configure (and mail us a description of what went wrong). Configure takes a number of options, but only the commonly-used ones are described here. You can specify the top-level installation directory with the "--prefix=" option, and the top-level installation directory for architecture-dependent binaries with "--exec_prefix=". Both options default to /usr/local. If you want, after running configure you can look at the Makefile and modify some of the options. B. Type "make". This creates a library archive call "libvpr.a" and an application called "vprender". C. Type "make install" to install the library, include files, and application. D. To run the demo, cd to the demo subdirectory and follow the instructions in the README file. It is not necessary to run "make install" before running the demo. 3. Documentation ---------------- Since vprender is intended to be a demonstration program, not a turn-key application, there is currently not a lot of documentation. Most of the new Tcl commands provided by vprender are calls to the C routines provided by VolPack. The VolPack man pages describe the functionality of these commands. See cmdtable.txt in the vprender source directory for a list of the Tcl command names and brief help messages. If you want to include the Tcl bindings with other packages in your own version of wish, then link your application against libvpr.a and call the C function Vpr_Init(Tcl_interp *interp) in your Tcl_AppInit function. The include file "vpr.h" contains a declaration for Vpr_Init. Vprender also comes with a set of [incr Tcl] classes. There are two basic classes: an array class and a rendering context class. See array.doc and context.doc in the library directory for basic documentation on these classes. The sample code in that directory includes a volume slicing tool (slicer.tcl) and a volume viewing tool (viewer.tcl). Sample code using the [incr Tcl] classes can be found in the example/ and demo/ directories. Also see the FAQ file. 4. Support ---------- If you have problems, bug reports or bug fixes, please send mail to: volpack@graphics.stanford.edu The author makes no commitment to fix bugs or provide support. Vprender is intended primarily as a demonstration program, so bugs and features in the VolPack library receive priority over vprender. But if you like vprender then drop us a note describing what you use it for! If you decide to use the software then please add yourself to our mailing list so we can tell you about bug fixes and new versions of the software. Just send a message to majordomo@lists.stanford.edu with the message body: subscribe volpack-announce 5. Data Sets ------------ Sample data sets are available from the Stanford Computer Graphics Laboratory's ftp site: graphics.stanford.edu:pub/volpack or http://www-graphics.stanford.edu/ 6.

Credits ---------- VolPack and vprender were written by Phil Lacroute at the Computer Graphics Laboratory, Stanford University. The algorithms are based on Phil's Ph.D. thesis research and are described in the following paper: Philippe Lacroute and Marc Levoy, Fast Volume Rendering Using a Shear-Warp Factorization of the Viewing Transformation, Proc. SIGGRAPH '94 (Orlando, Florida, July 24-29, 1994). In Computer Graphics Proceedings, Annual Conference Series, 1994, ACM SIGGRAPH, pp. 451-458. If you publish a rendering made using VolPack and you would like to make an attribution, the following form is suggested: Image generated using the Stanford VolPack volume renderer. An appropriate longer attribution could omit the word Stanford but would include a citation of the SIGGRAPH '94 paper: Image generated using the VolPack volume renderer [#]. [#] Philippe Lacroute and Marc Levoy, Fast Volume Rendering Using a Shear-Warp Factorization of the Viewing Transformation, Proc. SIGGRAPH '94 (Orlando, Florida, July 24-29, 1994). In Computer Graphics Proceedings, Annual Conference Series, 1994, ACM SIGGRAPH, pp. 451-458. The Tcl scripting language and Tk toolkit were designed and implemented by John Ousterhout at Berkeley. They made implementation of the GUI and the powerful script-based user interface far easier than any other toolkit I have seen.
