- Release 0.51, 10.12.1994 by Thomas Engel (tomi@shinto.nbg.sub.org)
-
-
-
- The 3DDeviceServer
- Application
-
- ATTENTION..you need gnutar and gzip to unpack this package.
-
-
- This NeXTSTEP application is a general purpose device server. It is
- the central part of a collection of various device drivers for many
- different 3D hardware tools. With the help of NeXTs DO/PDO system it
- will allow an easy 'plug-in' into existing software that may run
- distributed accross a network.
-
- The server tries to simplify shared access to one hardware device by
- multiple clients (or as I call them: device targets). In addition to
- that it will allow switching between different devices while they are
- in use.
-
-
-
- Using the Server
-
-
- Just start the server. When you click on one of the buttons from the
- Device windows scrollview, the corresponding driver will become
- active. Detailed information on how to use the program can be found
- inside the online help system.
-
- For more information on how to use the server in your own projects
- please read the tutorial in the second chapter.
-
-
- The Package
-
- Version 0.51 comes in two packages:
-
- - 3DDeviceServer.app & Documentation.
- The 3DDeviceServer.0.51.NIHS.bd.tar.gz archive contains a plug'n'play
- binary for NeXT, Intel, HP and Sparc hardware that was compiled under
- NeXTSTEP v3.3.
-
- - Source.
- In 3DDeviceServer.0.51.s.tar.gz you can find the
- complete sourcecode for this project. More details on compiling are
- included below.
-
- On where to find the latest releases please see the 'About this
- Project' section.
-
-
- Features
-
- This project is still some kind of beta although it runs very stable.
- From all the possible devices that this server offers access methods
- for (mouse, glove, display, scanner, motionTracker) only the mouse
- method will return a valid driver. Right now I only have a 3D mouse
- API. If you would like to help designing APIs for other equipment
- please let me know.
-
- The connections to devices work via the servers PDO port named
- "<hostname>/3DDeviceServer". For more details read the Release Notes
- and some History.
-
- The only 3D mouse the server knows about at the moment is the
- SpaceMouse (Driver release v0.8). It is the only mouse I own. In my
- opinion it is the best 3D mouse solution I have seen so far. More
- information about the hardware can be found in the online help.
-
- The other 'mouse' is the Virtual 3D Mouse (Driver release v0.6). It
- is just a simple GUI (slider based) pseudo mouse. Good for testing
- your software and for setting exact rotation values.
-
- If you own a different kind of 3D input device it should be straight
- forward to write a driver yourself and include it into the server.
-
-
- Supporting Software
-
- Currently (as of 10.12.94) there is one publicly available
- application that is able to use this server. But others projects are
- underway.
-
- BeakerBoy.
- My privat chemistry program…and the reason why I
- wrote this server. Version 0.3 will include 3D mouse support but is
- not ready yet because I need to include the IconKit before I put it
- on the net archives. The code used to handle to 3D mouse events
- can be found inside the tutorial.
-
- solidThinking MODELER.
- Guido Quaroni from Gestel was one of the
- early supporters of this server. He is trying to include 3D mouse
- control into the v2.2 release that might be be around sometime in mid
- '95.
-
- HippoDraw.
- The Reason Gang enhanced NeXTs original Draw demo
- application to allow displaying n-tuple data and the relations
- between certain columns of the tables. Mouse support should be around
- by Q1/95.
-
- WavesWorld.
- This free collection of objects and InterfaceBuilder
- palettes was created by Michael B. Johnson. It allows RenderMan
- objects to be controlled by TCL scripts or other control object.
- Mouse support should be around once the rotation handling of the
- WW3DWell class has cleaned up a little.
-
- For details on the support I might give other programmers please read
- the tutorial. If you are a user and would like to use a 3D mouse in
- your vavorite application you should contact its developers. Maybe
- they haven't heard of this server or they think it is not worth 10-20
- minutes of programming unless someone needs it.
-
-
- Future plans
-
- Here are the most wanted improvements form my ToDo-list. More can be
- found in the online help.
-
- - Loading the drivers from bundles. Well quite easy but it
- needs some time until the MiscFile classes have come to a rest.
-
- - I like datagloves so I might take a look at the PowerGlove
- code moving around the net. Gloves might be a subclass of 3DMouse
- adding absolut postitons (transformationEvent:isAbsolut:) and data
- about the fingers (fingerEvent:). This way 3D mouse systems with
- absolut positions could work as gloves as well. We might also have a
- right… and leftGlove in our server.
-
-
-
- About this Project
-
- Development will continue – but not at very high speed because my
- main project is still the BeakerBoy application. At this moment it is
- still not clear if the driver objects and this server program will
- find their way into the MiscKit project. Maybe with a Misc3DKit this
- might get more realistic. Anyway, the MiscRtMatrix is necessary to use
- this server in your applications.
-
- The latest version of this server will be available at the
- ftp.informatik.uni-muenchen.de or ftp.cs.orst.edu anonymous ftp
- servers. SpaceControl will have access to the latest version too, so
- when you want to buy a mouse just tell them that you are using a
- NeXTSTEP system. This will cost no extra charge! (as they assured me)
-
-
- Compiling
-
- This version includes all the source code needed to just compile the
- program from scratch but it does not include objects that are part of
- the MiscKit distribution. So if you need to recompile the application
- you will need to get the MiscKit project from the archives (Version
- 1.2.8 or higher)
-
- For more details on the MiscKit collection see the ftp servers
- mentioned above or get the Objective-C or NeXT FAQs. If you would
- like to submit something to this collection you should contact: Don
- Yacktman <don@darth.byu.edu>
-

- In Case of Trouble
-
- If you have any questions you might contact me.

-
- I would like to thank my brother (IconDesign), Matt Brandts
- (MiscSerialPort), DLR & SpaceControl (hardware questions), Guido
- Quaroni (software support) and NeXT (DOs are quite cool) for making
- my work easier.

- Warrenty and copyright
-
- Copyleft
-
- Source code that is not part of the MiscKit project - and therefore
- underlies the MiscKit distribution and copyright rules - is
- distributed under the GNUpublic license.
-
- If you want to write a device driver that you would like to sell,
- please contact me.
-
-
- No Warrenty
-
- This software is provided 'as is' and the programmer is not
- responsible for any harm this program may cause. You - the user - are
- responsible for everything that may happen to your business,
- hardware, software, car, CD collection or what ever may be worth your
- attention or money. Using this product is at your own risk and
- your private fun.
-
- There should be no serious bugs inside but remember that a
- carbon-based unit did the coding.
-
-
- TravelWare
-
- Like all my projects this app is free and should be considered as
- travel-ware.
-
- 1. Let it travel to as many people as you know.
-
- 2. Send me a postcard or E-mail if you use it. I will try to
- keep you informed about new releases.
-
- 3. If you have a free bed or some free space on your floor... give
- me a hint. I might come and visit you on my trip to the US
- (locations on Hawaii, near Seattle or WhistlerMnt. (Canada)
- preferred)
-
-
-
- Enjoy it.
