- This is the release announcement for the IRIT 7.0 solid
- modeling environment. One can find information on the IRIT environment
- at:
-
- http://www.cs.technion.ac.il/~irit
-
- IRIT 7.0 was fully tested on the following platforms. Previous
- versions were tested on other platforms and it is expected that IRIT
- will compile on them with minor or no revisions at all.
-
- * SGI4D (IRIX 4.0.1, IRIX 5.x).
- * SUN 4 (SunOS Release 4.1.2, Solaris)
- * Dec (Alpha AXP running OSF1.3)
- * IBM PC (Window NT 3.5/4.0, Windows 95, OS2 3.0 Warp)
- * Amiga (AmigaDOS 2.1)
-
- Many thanks should go to Kriton Kyrimis for the Amiga port.
-
- The distribution locations below have C sources as
- irit70src.*, documentation is available as postscript files
- (irit70ps.*), man pages (irit70man.*), and http files
- (irit70www.*). Executables for OS2 3.0 as irit70os2.* and
- executables for Windows NT/95 as irit70nt95.*
-
- You can anonymous ftp IRIT 7.0 from the following locations:
-
- * ftp.cs.technion.ac.il [132.68.32.21], directory /pub/misc/gershon/irit
- The is the homeland for Irit.
- (contact person gershon@cs.technion.ac.il (Gershon Elber)).
-
- * ftp.uu.net [192.48.96.9], directory /graphics/irit
- (contact archive@uunet.uu.net)
-
- * gondwana.ecr.mu.oz.au [128.250.70.62], /pub
- (contact person bernie@ecr.mu.oz.au (Bernie Kirby)).
-
- * ftp-os2.nmsu.edu [128.123.35.151] os2/graphics.
- This has only the executables. Sources should be ftp'ed from one
- of the unix places above.
-
- * wuarchive.wustl.edu [128.252.135.4] pub/aminet/gfx/3d
- has the Amiga port of IRIT 7.0.
- (contact person kyrimis@cti.gr (Kriton Kyrimis)).
-
- At this time, ftp.technion.ac.il, ftp.uu.net, and gondwana.ecr.mu.oz.au
- all has the new release in place. I expect the os2 and amiga ports to
- be in place in the very near future.
-
- Below you will find the update notes for 7.0.
-
- Enjoy,

- -----------------------------------------------------------------------------
- * Display devices for Windows NT/95 and OS2 are now stable.
- * Alpha channel is now properly working in irender.
- * IRIT is now fully working on Windows 95 with no network (use to have
- IPC problems).
- * Several global name renaming in C space (EPSILON -> IRIT_EPS etc.).
- * New irit2pov - IRIT to POVRAY filter.
- * Primitive constructors (spheres, cones, etc) can now create freeform
- exact rational surfaces as well as approximated polynomial surfaces.
- * Fix two bugs in BBOX of lists and points.
- * Support for triangular (Bezier) patches has been added.
- * Ability to evaluate a scene at a prescribed animation time in many of the
- tools, such as irender, poly3d-h and the some filters.
- * Irender now supports surface function texture useful for curvature display
- as well as contouring texture.
- * Instances of geometry are supported (not completely) via a new instance
- type.
- * FFCOMPAT also works on trivariates.
- * C/SREPARAM works correctly on float/periodic end conditions.
- * OFFSET and RULEDSRF now works on polyline/gons.
- * SINTERP now allows scattered data (with UV's).
