DIGITAL Open3D supports the X Window System client/server model for network-transparent graphics and win- dowing. The ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, PowerStorm 3D30/4D20, and PowerStorm 4D40T/50T/60T families of graphics servers provided with DIGITAL Open3D can display output from: July 1997 AE-QZC0E-TE o 2D client applications supporting Release 6 of the X Window System, Version 11 (X11R6) o 3D client applications supporting the OpenGL 3D extensions to the X Window System The ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, and PowerStorm 3D30/4D20 graph- ics servers provided with DIGITAL Open3D can also display output from 3D client applications supporting PEX 3D extensions to the X Window System. Moreover, DIGITAL Open3D includes the DIGITAL implementation of the PEXlib API, provided as two programming libraries. DIGITAL Open3D provides X- and OpenGL-compliant servers for the ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, PowerStorm 3D30/4D20, and PowerStorm 4D40T/50T/60T graphics accelerators. Furthermore, DIGITAL Open3D includes the DIGITAL implementation of the OpenGL application programming interface (API), provided as a set of programming libraries. Another component of DIGITAL Open3D is the ability to run OpenGL on the PowerStorm 3D10 via a software-only implementation of the OpenGL server extension. In addition to the various servers, server extensions, and libraries, DIGITAL Open3D also includes a run-time version of DIGITAL PHIGS (Programmers Hierarchical Interactive Graphics System). DIGITAL PHIGS is a sophis- ticated three-dimensional graphics support system that defines, mod- ifies, organizes, and displays hierarchical, graphical data. DIGITAL PHIGS supports OpenGL, which allows DIGITAL PHIGS applications to be displayed on Alpha workstations with DIGITAL Open3D. DIGITAL PHIGS is also available as an optional layered product sup- porting DIGITAL Open3D. For more details, see the DIGITAL PHIGS for DIGITAL UNIX Software Product Description 44.62.xx. 2 Other support provided by DIGITAL Open3D is the use of input devices. The usability of 3D applications can be enhanced with input devices such as a dial or button box. To enable developers to support these devices within their own applications, DIGITAL Open3D provides the Peripheral Control Module (PCM) server and the Input Device Library (IDL). DIGITAL Open3D now supports Common Desktop Environment (CDE), the new default graphical user interface for DIGITAL UNIX. CDE provides a con- sistent user interface for end users and a coherent development en- vironment for application developers across multiple UNIX platforms. CDE on DIGITAL UNIX is based on the X Window System Release 6 (X11R6) and CDE/Motif Version 1.0 (OSF/Motif 1.2.4), and is available for DIGITAL Open3D and other products running on DIGITAL UNIX. Graphics Servers DIGITAL Open3D provides the device-dependent portions of the X11 dis- play server to support the ZLX-E, ZLX-L, and ZLX-M TURBOchannel graph- ics accelerators, as well as the ZLXp-E, ZLXp-L, PowerStorm 3D30/4D20, and PowerStorm 4D40T/50T/60T PCI graphics accelerators. These device- dependent portions include the device-dependent X layer, device drivers, server extensions, and hardware-specific microcode. The device-independent portions of the X11 display server are provided by the DIGITAL UNIX Operating System. The X11 display server provided with DIGITAL Open3D is a port of the standard X11R6 display server. By offering this server, DIGITAL can consistently incorporate X Consortium display server enhancements in future releases of DIGITAL Open3D. Extension Support In addition to support for core X11R6, all X servers on DIGITAL UNIX support the following extensions: o X Imaging Extension (XIE) o XTRAP o SHAPE 3 o MIT multibuffering o DPS (Display PostScript) o MIT SHM (Shared Memory) o XInputExtension o DECStereo Extension (ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, and PowerStorm 3D30/4D20, families of options) o Support for Overlays (ZLX-E2, ZLX-E3, ZLX-L family, ZLX-M family, ZLXp-E2, ZLXp-E3, ZLXp-L family, PowerStorm 4D20, and PowerStorm 4D40T/ 50T/60T options) o MITmisc The DIGITAL Open3D ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, PowerStorm 3D30/4D20, and PowerStorm 4D40T/50T/60T families of graphics servers support the following additional extension: Version 1.1 of the OpenGL Extension to the X Window System (GLX), as defined by the OpenGL Architecture Review Board. GLX allows an OpenGL client on one vendor's platform to run across a network and display the results on another vendor's server. The DIGITAL Open3D ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, and PowerStorm 3D30/4D20 graphics servers support the following additional extension: Version 5.1 of the PEX protocol as defined by the X Consortium. PEX is a 3D extension to the X Window System, which provides network- transparent 3D graphics. X, OpenGL and PEX applications can run simultaneously on the follow- ing graphics servers: ZLX-E ZLX-L ZLX-M ZLXp-E ZLXp-L 4 PowerStorm 3D10 (not PEX) PowerStorm 3D30 PowerStorm 4D20 PowerStorm 4D40T (not PEX) PowerStorm 4D50T (not PEX) PowerStorm 4D60T (not PEX) PEX Version 5.1 Protocol (Not Fully Supported by DIGITAL Open3D Graphics Server) The PEX 5.1 specification defined by MIT on the X11R6 distribution in- cludes some protocol packets that are neither supported by the graph- ics server provided with DIGITAL Open3D, nor generated by the DIGITAL implementation of PEXlib. The server can be queried for a list of the features it supports (for example, protocol packets). In particular, the following features are not supported: o Workstation object o Picking (supported only through the DIGITAL implementation of PEXlib) o Search contexts o Full font support o Modeling clip o Certain interior styles, color types, HLHSR modes, and prompt/echo types Server Enhancements The DIGITAL Open3D ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, PowerStorm 3D30/4D20, and PowerStorm 4D40T/50T/60T families of graphics servers support ad- ditional hardware features of the corresponding graphics accelerators through a set of library routines and device-specific server exten- sions. These libraries and server extensions allow the application de- veloper to access the overlay planes and stereo viewing hardware (when applicable) on these units. 5 Both singlehead and multihead (the simultaneous use of more than one graphics accelerator) configurations are supported. The multihead sup- port is subject to the TURBOchannel or PCI slot limitations of the work- station. The supported configurations are as follows: o TURBOchannel Options: - All ZLX options work with the HX option. - All options support homogeneous 3D/3D multihead. This means that up to three ZLX-E, ZLX-L, or ZLX-M can run on a workstation, and 3D is supported on each of the heads. - The ZLX-E options support homogeneous 2D/2D or 2D/3D multihead. Up to three ZLX-E options are supported; this means that one ZLX-E option can run 2D while other ZLX-E options run 2D or 3D. - The ZLX-L and ZLX-M options support heterogeneous 3D/2D multi- head with the ZLX-E options. This means that the ZLX-L or ZLX-M can run 3D while the ZLX-E runs 2D. o PCI Options: - One PowerStorm 3D10 option is supported and cannot be combined with any other device. - One ZLXp-L1 or ZLXp-L2 is supported and cannot be combined with any other device. - Up to three PowerStorm 3D30 options, or three PowerStorm 4D20 options, or three PowerStorm 3D30/4D20 options are supported, running any combination of 2D/3D. (On AlphaStation 255 proces- sors, and Digital Personal Workstation 433au and 500au proces- sors, only two PowerStorm 3D30 options, or two PowerStorm 4D20 options, or two PowerStorm 3D30/4D20 options are supported.) - Up to four PowerStorm 3D30 options or four PowerStorm 4D20 op- tions are supported running 2D only and on AlphaStation 600 pro- cessors only. 6 - The ZLXp-E options support homogeneous multihead. This means that up to three ZLXp-E options can run on an AlphaStation, and 3D is supported on each of the heads. - The ZLXp-E options also support homogeneous 2D/2D or 2D/3D mul- tihead. Up to three ZLXp-E options are supported; this means that one ZLXp-E option can run 2D while other ZLXp-E options run 2D or 3D. - Up to two PowerStorm 4D40T options are supported. Peripheral Control Module Server The usability of many graphics applications is enhanced by input de- vices other than a keyboard, tablet, or mouse. The Peripheral Control Module (PCM) server controls the following alternate input devices: o Lighted Programmable Function Keys (LPFK), also known as a "but- ton box." This device has 32 keys arranged in a matrix, each with an LED. o Programmable Function Dials (PFD), also known as a "dial box." This device has eight dials arranged in a 4 x 2 matrix. Programming Support DIGITAL Open3D includes an extensive set of programming libraries for building 2D and 3D applications. Two categories of programming libraries are provided with DIGITAL Open3D: o 3D rendering APIs: OpenGL and PEXlib o Input Device Library (IDL), a DIGITAL added-value library that al- lows programmers to access the capabilities of devices supported by the PCM server. Programming support is also provided by the DIGITAL UNIX Operating Sys- tem, which includes the standard X and OSF/Motif libraries and tools (Xlib, Xtoolkit intrinsics, OSF/Motif UIL compiler), and DIGITAL added- value extensions. Used with the DIGITAL Open3D libraries, the DIGITAL 7 UNIX standard graphics and windowing APIs provide a robust environ- ment for developers creating interactive 2D and 3D graphics applica- tions. For more details on the graphics programming environment provided with the DIGITAL UNIX Operating System, see the Software Product Descrip- tion 41.61.xx. OpenGL OpenGL is the software interface that enables application developers to produce high quality images of 3D objects. OpenGL has been designed to work with various operating and window system environments. The ver- sion of OpenGL supplied as part of DIGITAL Open3D has been integrated with the X Window System, which allows the support of network-transparent 3D graphics. The OpenGL API and X protocol extensions are defined by the OpenGL Architecture Review Board, of which DIGITAL is a founding member. To enhance the compatibility of different vendors' implementations of OpenGL, a suite of conformance tests has been developed to determine if a vendor's im- plementation of OpenGL conforms to the specification. The DIGITAL im- plementation of OpenGL has passed all tests required of a conformant implementation of OpenGL per the following: o OpenGL Version 1.0, GLX Version 1.1, and OpenGL Utility Library (GLU) Version 1.2 running the ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, PowerStorm 3D30, and PowerStorm 4D20 o OpenGL Version 1.1, GLX Version 1.2, and OpenGL Utility Library (GLU) Version 1.2 running the PowerStorm 4D40T, PowerStorm 4D50T, and PowerStorm 4D60T OpenGL is packaged as a set of dynamic shared libraries against which an application is linked. The shareable images are activated at run- time as needed. 8 OpenGL supports a wide variety of 2D and 3D functionality, including: o Graphics primitives - Points - Lines - Polylines - Fill area - Triangle strips - Triangle fans - Quadrilateral meshes - Trimmed and untrimmed NURBs (nonuniform rational B-splines) o Object properties - Line type and width - Color - Character attributes o Viewing and transformation operations o Rendering styles - Flat shading - Smooth shading - Hidden line hidden surface removal (HLHSR) o Advanced rendering features - Antialiasing - Texture mapping - Alpha blending - Transparency 9 - Accumulation buffers for effects such as depth of field, motion blur, shadows, and fog PEXlib DIGITAL Open3D includes two programming interfaces to the PEX proto- col: MIT PEXlib and the enhanced PEX library of DIGITAL. Both PEX li- braries generate PEX Version 5.1-compatible protocol, as defined by the X Consortium. Each version of PEXlib is packaged as a dynamic shared library to which an application is linked. The shareable images are activated at run- time as needed. A static version of the libraries is also provided. Functionality Provided by the DIGITAL Implementation of PEXlib (MPEX extensions) The following added-value features (MPEX extensions) are supported by the DIGITAL implementation of PEXlib, but are not part of the MIT X11R6 PEXlib distribution: o Antialiased lines o Transparency o Indexed polygons o Highlighting for rendering and pick o Unpacked data output commands o Line styles o User-defined markers o Circles, ellipses, circular arcs, and elliptical arcs o Annotation pixmaps o Slanted text 10 Input Device Library The Input Device Library (IDL) provides programmers with access to the hardware devices supported by the PCM server. With this library, ap- plications can control which buttons and/or dials they listen to, and more than one application can simultaneously receive the data. This library also enables an application to control the smoothing and threshold functions of the dial box, varying the sensitivity to suit the application. DIGITAL PHIGS uses this library to provide Choice and Valuator inputs to programs. Character Fonts DIGITAL Open3D includes a series of stroke precision character fonts. These character fonts were digitized by Dr. Allen V. Hershey of the Naval Surface Weapons Laboratory, and supplied to DIGITAL by the National Bureau of Standards. CONFORMANCE TO STANDARDS The following have passed the tests required of a conformant imple- mentation of OpenGL Version 1.0, GLX Version 1.1, and GLU Version 1.2: o The DIGITAL implementation of OpenGL o ZLX-E, ZLX-L, ZLX-M, ZLXp-E, ZLXp-L, and PowerStorm 3D30/4D20 servers The following have passed the tests required of a conformant imple- mentation of OpenGL Version 1.1, GLX Version 1.2, and

space required during and after installation (files uncompressed): 65 MB These figures refer to the disk space required on the system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options. Memory Requirements for Motif: The minimum supported memory for DIGITAL Open3D running in a standalone Motif environment, with both the client and server executing on the same system, is 32 MB. The memory size suggested for most typical hard- ware configurations, however, is 64 MB or more, depending on the sys- tem. The system configuration and performance requirements of Motif appli- cations can determine the memory needed on your system as follows: o Less memory may be required on the client system (where the soft- ware is installed and executed) if the server (component display- ing the application) resides on another system. o More memory may be required on a system where improved performance is desired, or where several applications are running. 16 OPTIONAL HARDWARE DIGITAL Open3D Version 4.4 supports the following optional input de- vices: o Lighted Programmable Function Keyboard o Programmable Function Dials (dial box) Other devices that can be used are: o 30.5 x 30.5 cm (12 x 12 inch) tablet, mouse substitute only-on AlphaStations only o 28 x 28 cm (11 x 11 inch) tablet, mouse substitute only-on TURBOchannel systems only SOFTWARE REQUIREMENTS DIGITAL Open3D Version 4.4 requires the following operating system: DIGITAL UNIX Operating System Version 4.0a, 4.0b, or 4.0c DIGITAL Open3D Version 4.4 requires the following language for the de- velopment of applications and programs that use DIGITAL Open3D on DIGITAL UNIX: DIGITAL UNIX C Developers' Extensions OPTIONAL SOFTWARE The following optional software can be used with DIGITAL Open3D Version 4.4: DIGITAL PHIGS Version 5.1 for DIGITAL UNIX DIGITAL GKS-the version supported by the DIGITAL UNIX version in- stalled on your machine Note: Certain versions of these products depend on a specific version of the operating system.
