For more informa- tion about its features, refer to the DECwindows Motif for OpenVMS Alpha Software Product Description (SPD 42.19.xx). In conjunction with DECwindows Motif, DIGITAL Open3D provides a complete development and run-time en- vironment for 2D and 3D applications. DIGITAL Open3D supports the X Window System client/server model for network-transparent graphics and windowing. The DECwindows X11 dis- play server provided with DIGITAL Open3D can display output from: 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 January 1998 AE-PZQ1T-TE The ZLXp-L and PowerStorm 3D30/4D20 graphics servers provided with DIGITAL Open3D can also display output from 3D client applications support- ing 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 ZLXp-L and PowerStorm 3D30/4D20 graphics accelerators. Furthermore, DIGITAL Open3D includes the DIGITAL implementation of the OpenGL application programming interface (API), provided as a set of programming libraries. 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 OpenVMS. CDE provides a consis- tent user interface for end users and a coherent development environ- ment for application developers across multiple OpenVMS platforms. Graphics Servers DIGITAL Open3D provides the device-dependent portions of the DECwindows X11 display server to support the ZLXp-L and PowerStorm 3D30/4D20 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 dis- play server are provided by DECwindows Motif for OpenVMS Alpha. The DECwindows 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. 2 Extension Support In addition to support for core X11R6, all DECwindows servers support the following extensions through DECwindows Motif: o X Imaging Extension (XIE) o XTRAP o SHAPE o MIT multibuffering o DPS (Display PostScript) o MIT SHM (Shared Memory) o XInputExtension o DECStereo Extension (ZLXp-L and PowerStorm 3D30/4D20 families of options) o Support for Overlays (ZLXp-L family and PowerStorm 4D20) o MITmisc For more details on these extensions, refer to the DECwindows Motif for OpenVMS Alpha Software Product Description (SPD 42.19.xx). The DIGITAL Open3D ZLXp-L family of graphics servers, and the PowerStorm 3D30/4D20 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 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. 3 X, OpenGL, and PEX applications can run simultaneously on the follow- ing graphics servers: ZLXp-L PowerStorm 3D30 PowerStorm 4D20 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 ZLXp-L family of graphics servers, and the PowerStorm 3D30/4D20 graphics servers, support additional hardware features of the corresponding graphics accelerators through a set of library routines and device-specific server extensions. These libraries and server extensions allow the application developer to access the overlay planes and stereo viewing hardware (when applicable) on these units. 4 Both singlehead and multihead (the simultaneous use of more than one graphics accelerator) configurations are supported. The multihead sup- port is subject to the PCI slot limitations of the workstation. The supported PCI Option configurations are as follows: o One ZLXp-L1 or ZLXp-L2 is supported and cannot be combined with any other device. o Up to three PowerStorm 3D30 options, or three PowerStorm 4D20 op- tions, or three PowerStorm 3D30/4D20 options are supported, run- ning any combination of 2D/3D. On AlphaStation 255 processors; only two PowerStorm 3D30 options, or two PowerStorm 4D20 options, or two PowerStorm 3D30/4D20 options are supported. o Up to four PowerStorm 3D30 options or four PowerStorm 4D20 options are supported running 2D only and on AlphaStation 600 processors only. 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 5 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 DECwindows Motif for OpenVMS Alpha Operating System, 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 li- braries, the DECwindows Motif standard graphics and windowing APIs pro- vide a robust environment for developers creating interactive 2D and 3D graphics applications. For more details on the graphics programming environment provided with the DECwindows Motif for OpenVMS Alpha Operating System, see the Soft- ware Product Description 42.19.xx. Digital PHIGS for OpenVMS Alpha is also available as an optional lay- ered product supporting DIGITAL Open3D. Digital PHIGS is a sophisti- cated three-dimensional graphics support system that defines, modi- fies, organizes, and displays hierarchical, graphical data. Digital PHIGS supports OpenGL, which allows Digital PHIGS applications to be displayed on Alpha workstations with DIGITAL Open3D. For more details, see the Digital PHIGS for OpenVMS Alpha Software Product Description 44.45.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 6 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 Version 1.0, GLX Version 1.1, and OpenGL Util- ity Library (GLU) Version 1.2. 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. 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) 7 o Advanced rendering features - Antialiasing - Texture mapping - Alpha blending - Transparency - 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. 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 8 o Circles, ellipses, circular arcs, and elliptical arcs o Annotation pixmaps o Slanted text 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.
