-
- Highlights of This Release (details below):
-
- - Windows95 Support! (Beta Release)
-
- - Complete VRML 1.0 Support!
-
- - GZIP Support!
-
- - HTML Browser Integration
-
-
- Details:
-
- - Windows95 Support
-
- This release of WebSpace for Win32 will run on both WindowsNT and
- Windows95. See the README.TXT file for system requirements and so
- on, but a 486DX2/66 with 8MB of memory seems to work just fine.
-
- NOTE: For Windows NT this is the production release of WebSpace 1.0.
- For Windows 95 this is the Beta2 release of WebSpace 1.0.
- Same executable, different level of stability. For Windows 95
- we are currently using a pre-release version of Microsoft's
- OpenGL implementation.
-
- - Complete VRML 1.0 Support, including:
-
- + WWWAnchor Node
- WebSpace/Win32 now changes the cursor to indicate the presence
- of a linked object (instead of changing the object's color).
- WebSpace/Win32 now displays the WWWAnchor's "description" field
- by default, with an option to display the actual URL. Check it
- out, some authors are making very creative use of descriptions.
- Also note that in WebSpace a WWWAnchor can be linked to any URL,
- not just other VRML files. See "HTML Browser Integration" below.
-
- + WWWInline Node
- WebSpace/Win32 now supports nested WWWInlines and downloads them
- in the "background" so you can navigate freely through the scene
- while the WWWInlines are being fetched. When authors use this
- feature effectively, you get an effect similar to the way your
- HTML browser displays the text while it's still fetching images.
- The "placeholder" for a WWWInline is a wireframe bounding box.
- This is definitely the way to go if you only have a modem!
-
- + Texture Node
- WebSpace/Win32 now supports texture maps provided as either GIF
- or JPEG files (sorry, no support for .rgb files in this release).
- Like Inlines, texture maps are fetched asynchronously, allowing
- you to navigate freely through the scene as soon as it appears.
- Without a hardware accelerator, it's still not practical to move
- around with the textures applied, but by default WebSpace turns
- textures off while you're moving and back on when you stop. The
- visual effects are great, but watch out for scenes that have a
- large number of large texture maps! You can't always tell from
- the size of the VRML file how long it will take to download all
- the inlines and textures. Try the "gasbldg.wrl" example we've
- provided (this model was created at UCLA -- see their web page
- for author information).
-
- + LOD (Level Of Detail) Node
- You may have seen some of the discussion about this node on the
- VRML mailing list. Now try it out for yourself! It's true, you
- can even do "cheap tricks" like having a door open as you walk up
- to it. Of course this sort of cheap trick will be ever-so-tacky
- once we have "real behaviors" in VRML, but it's still fun. :-)
- Try the "loddoor.wrl" example we've provided. Hint: Turn off the
- "Degrade on Move" option in the View menu to see the door change
- while you are moving (otherwise WebSpace automatically uses the
- lowest level of detail while you are moving).
-
- + AsciiText and FontStyle Nodes
- Geez, how do you expect people to navigate through cyberspace if
- there are no signs! :-) Let's get some text in those worlds.
-
- + Other
- Of course WebSpace/Win32 still supports IndexedLineSet, PointSet,
- multiple cameras, multiple lights and all the common VRML "hints"
- including viewpoints. See the (HTML) help files that come with
- WebSpace for more information about hints.
-
-
- - GZIP Support
-
- Been wondering what's in all those mysterious ".gz" VRML files, but
- don't want to download and unzip them all by hand? No problem!
- WebSpace/Win32 now handles them automatically and wow, do they ever
- download quickly compared to the uncompressed versions. WebSpace
- handles gzip'd VRML files, WWWInline files and texture files. (See
- the README.TXT for important notes about configuring the HTML browser.)
-
-
- - HTML Browser Integration
-
- Don't you hate it when every time you click on a VRML link in your
- HTML browser it pops up another instance of your VRML browser? How
- about when you click on a WWWAnchor in your VRML and it pops up
- another instance of your HTML browser? Pretty tacky. The days of
- "passive" helper applications are over. WebSpace/Win32 works with
- Netscape, Mosaic and other browsers that support the DDE protocol.
- So only one instance of each browser appears. When you click on a
- WWWAnchor in WebSpace and it's not a VRML file, the link is handled
- by your HTML browser and your other helper applications. So you
- only configure your helper applications once, in your HTML browser!
- This opens up all kinds of possibilities for coordinated display of
- text, graphics and sound -- for example on-line instruction manuals.
-
- Note: We are currently working with a number of other HTML browser
- vendors to extend support for the DDE protocol and we invite all
- HTML browsers to work with us. We will be officially opening our
- browser integration testbed on our Web site this week. We are also
- working with browser vendors on other interface technologies like OLE.
-
-
- - Performance
-
- As promised, this release of WebSpace/Win32 is not only feature-rich
- but substantially faster than the Beta release. Of course there's no
- such thing as "fast enough" in this business, so we're continuing to
- work on rendering speed. The next release will be even faster.
-
-
- - SGI Logo
-
- Yes, that is the Silicon Graphics logo at the top of the WebSpace
- window. No, Silicon Graphics did not buy TGS!!! We are still an
- independent software company and we still continue to implement and
- support WebSpace for the Win32 environment. But, Silicon Graphics
- does own the trademark "WebSpace", so they can have their logo any
- where they want it. Note: We gratefully acknowledge the various
- pieces of SGI code from the UNIX version of WebSpace that we were able
- to re-use. See the About Box and other documents for copyright
- acknowledgements and other legal stuff. We are also pleased to be
- able to base WebSpace/Win32 on the totally awesome Open Inventor 3D
- toolkit, developed by SGI and integrated with Microsoft Windows by TGS.
-
-
- - New Tools
-
- WebSpace/Win32 now includes some useful tools for working with VRML:
-
- + VRMLLint
- A utility program that parses a file and verifies that it
- conforms to the VRML 1.0 specification. Note: This is a console
- application, so you have to run it from a command prompt.
-
- + IvToVRML
- A utility program that reads in an Open Inventor file and spits
- out a conforming VRML file. Note: This is a console application
- so you have to run it from a command prompt.
-
-
- - Open Inventor Files
-
- Oh yeah, WebSpace/Win32 can still read more than just VRML files.
- WebSpace/Win32 can also read Open Inventor ".iv" files. The Open
- Inventor file format is (roughly speaking) a superset of VRML and
- some additional Open Inventor nodes are being considered for the
- VRML 1.1 specification.
-
- Why would you want to do that? Well, there are some things you just
- can't do in VRML yet. For example you can use the LightModel node to
- tell the browser not to do lighting because vertex colors have already
- been computed, you can use the Environment node to specify the level
- of ambient light, and you can use the Complexity node to tell the
- browser it's OK to render built-in objects like cone and sphere with
- lower tessellation. That's why some sites have been maintaining two
- versions, one in VRML and one in Open Inventor, at least until the new
- features for VRML 1.1 are specified. There are also a growing number
- of applications that support the Open Inventor format as an export
- option. In the engineering design area, for example, check out:
- Parametric Technology, Unigraphics and SDRC .
-
- Please note however: Changing the header line and file extension does
- not necessarily turn an Open Inventor file into a VRML file! Either
- keep your Inventor files as Inventor files or use the tools we provide
- to convert and verify. In any case, you may want to try some of the
- Open Inventor files we provide as examples.
-
-
- - Miscellaneous
-
- + In the "Options" menu you can now specify the default viewer type.
- This is the viewer type, Walk or Examiner, that will be used when
- the VRML file does not contain a Viewer hint.
-
- + All option settings and bookmarks are now saved in the .ini file.
