Welcome to the Skunkware 98 Java section.

Package List

Acme Labs Java Software

These excellent Java classes were downloaded from Jef Poskanzer's ACME Laboratories. The ACME Labs home page is at http://www.acme.com/ and includes some remarkably useful freeware.

In addition to the Acme class library, i have also downloaded and packaged up a few of Jef's Java applications. These include :

WebCat

fetch URLs and write them to stdout

WebList

make a list of the files in a web subtree

WebCopy

copy a remote web subtree to the local disk

WebGrep

search a web subtree for a pattern

WebPost

post a web query and write the results to stdout

ToPpm

dump out an image URL as PPM

ToGif

dump out an image URL as GIF

Also included is the Java application wrapper script JavaWrapper and a sample shell script i wrote called webget which front-ends the action of WebCat.

The Acme class library gets extracted, by default, into /usr/local/java/Acme. The Java applications get extracted into /usr/local/java and the shell script wrappers get extracted into /usr/local/bin.

The JavaWrapper script checks to see if your CLASSPATH environment variable is set. If not, it sets it to /usr/local/java. If set, it checks to see if /usr/local/java is a component and, if not, appends that.

Many other useful and fun things are at ACME Laboratories.

If you have questions about the packaging of these classess, you may address them to me, Ron Record, via rr@sco.com.

Jasmin - Java Assembler Interface

Jasmin is a Java Assembler Interface. It takes ASCII descriptions for Java classes, written in a simple assembler-like syntax and using the Java Virtual Machine instruction set. It converts them into binary Java class files suitable for loading into a JVM implementation.

Description

VRwave is a freely available browser for 3D worlds and scenes modeled in VRML 2.0 (the latest version of the Virtual Reality Modeling Language). It is being developed by the Institute for Information Processing and Computer Supported New Media (IICM) of Graz University of Technology, Austria, the team who brought you the VRweb VRML 1.0 browser. Visit http://www.iicm.edu/ for information about the IICM.

VRwave is the only free VRML browser available in full source code which does not require commercial packages such as Inventor or Motif and which will run on (almost) any Unix or Windows platform. For more information on VRwave, visit http://www.iicm.edu/vrwave . The new name VRwave is intended to distinguish the VRML 2.0 browser written largely in Java from VRweb, which was written in C++. In terms of look and feel, VRwave is a direct successor to VRweb. For more information about VRweb, visit http://www.sco.com/skunkware/x11/viewers/ .

Productivity

This program displays VRML 2.0 files for the user to manipulate. When used with a web browser, such as Netscape or Mosaic, this 3D viewer allows access to the increasing number of web sites offering virtual reality content and to the advanced HyperWave servers (formerly known as "Hyper-G"). HyperWave servers represent the next generation web solution for publishing rich hypermedia documents in the Internet's World Wide Web and internal TCP/IP networks. For more information about HyperWave, visit http://www.hyperwave.de/.

Work Planned

None

Documentation

Preliminary on-line help for VRwave is included in the archive "Common-VRwave-0.9-Unix.tar.gz". For additional information, view the VRweb User Guide at http://www.iicm.edu/vrweb/help .

Verification

Run "vrwave filename &" (or "$VRWAVE_HOME/vrwave filename &"), where filename is any VRML 2.0 file. If VRweb (the C++ predecessor of VRwave) is executed, it will automatically invoke VRwave when a VRML 2.0 file is encountered. Both VRML 1.0 and VRML 2.0 files have a file suffix of ".wrl".

Known Limitations

Currently, VRwave for Unix is unable to process VRML 1.0 files. For more information, visit http://hiwaay.net/~crispen/vrml/faq.html#q2.

How to get the source

Visit http://www.sco.com/skunkware/ or ftp://ftp.sco.com/skunkware/src/x11/viewers to obtain a copy of the source in gzip format. To create the executable from the source code (on OpenServer 5.0.4), follow these steps:

• Install the "SVR5 based UnixWare release (codenamed Gemini)" version of the Universal Development Kit (UDK) and Java Development Kit 1.1 (JDK).
• Obtain (or build) and install the UDK version of the Mesa Graphics Library (version 2.4), which is available from SCO SkunkWare. Only the two primary Mesa libraries (libMesaGL.a and libMesaGLU.a) are required.
• Use ksh.
• Ensure that the execution search path includes the directory containing the UDK C/C++ compilers (e.g., "/udk/usr/ccs/bin") BEFORE any other compiler directories (e.g., "/usr/bin/" for the SCO Development System compilers).
• Execute the command: "export CPU=SCO".
• Decompress and untar the archive "vrwave-0.9.tar.gz".
• See file BUILDING for an installation guide.
• The unbuilt source directory hierarchy requires about 3 Meg, and the built hierarchy requires about 5 Meg of disk space. The shared object is under 1 Meg.
• Decompress and untar the archive "Common-VRwave-0.9-Unix.tar.gz".
• Set environment variable VRWAVE_HOME to the directory which was created on unpacking the archive (vrwave-0.9). This directory contains the vrwave wrapper script, help, icons, etc.
