Added: cgm/trunk/README.OCC =================================================================== --- cgm/trunk/README.OCC (rev 0) +++ cgm/trunk/README.OCC 2008-12-08 19:57:06 UTC (rev 2473) @@ -0,0 +1,80 @@ +===================================== +Read Me for CGM on OCC +===================================== + +CGM can be built upon the ACIS solid modeling engine or OCC solid +modeling engine, but also includes geometry capability developed +beside and on top of them. +CGM is supported on Sun Solaris, SGI, HP, Linux and Windows NT +platforms. CGM also includes support for loading OCC +models on parallel computers. +CGM is being released into the public domain under an LGPL license; +the OCC-based engine is available from Opencascade open source downloads. + +===================================== +Build OCC-based engine +===================================== + +Go to http://www.opencascade.org/getocc/download/loadocc/ and get +desired source files. + +Untar the files, then under OpenCASCADE6.3.0/ros directory, to +autoreconf -fi +./configure (Add --prefix=dir for your install directory) +make +make install + +===================================== +Dependencies +===================================== + +CGM can be built using the CMake utility, which is "an extensible, +open-source system that manages the build process in an operating +system and compiler independent manner", or (on *NIX) using a +configure-make system. Cmake is available under an open source +license, and can be downloaded in binary or source formats; see +http://www.cmake.org for details. + +===================================== +Compiling +===================================== + +1. Unpack the source code in some directory CGM_DIR, and change +directory into CGM_DIR. +2a. Run cmake in that directory, using either the non-interactive +("cmake .") or interactive ("ccmake .") version, OR +2b. Run "./configure" in that directory, optionally specifying where +ACIS libraries are located and other options (run "./configure -h" for +a list of options). +3. Make the CGM libraries by typing "make". +4. Install the CGM libraries by typing "make install" (this installs +the libraries to the location specified by the --prefix option to +configure, or to /usr/local by default). +5. Test the installation using "make test". + +===================================== +Documentation, Testing, Example Applications +===================================== + +Documentation for CGM is available from the CGM web page, +http://cubit.sandia.gov/CGM. + +Example applications are included with the CGM distribution in the +"test" subdirectory. Examples include importing and querying solid +model-based geometry, and constructing OCC-based geometry. If you +are interested in contributing examples to be included with CGM, we +would welcome submissions; please send them to the email address +below. + +===================================== +Bugs, Correspondence, Contributing +===================================== + +CGM on OCC code is now in alpha testing stage, we encourage users to +submit bug reports (and, if desired, fixes) to [email protected] . + +===================================== +Updates +===================================== + +This is the first version of the file
