- A.0 Introduction
-
- The MicroStation Driver is a protected-mode driver designed to
- improve the user interface of MicroStation products by implementing the
- full resolution of your graphics board and monitor and by providing
- the means to customize some of the presentation parameters.
-
-
- A.1 Key Features
-
- The most important features that our MicroStation Driver offers to Users
- include:
-
- * Full support for Microstation version 4.0,
-
- * Full 32-bit performance for all drawing operations, generally
- providing about 10% better performance than the drivers shipped with
- MicroStation.
-
- * Full dual screen support for dual graphics monitor support with the
- mach64 graphics boards.
-
- * Anti-aliasing for jaggie free displays.
-
- * Protected-mode design allows it to become an integral part of the
- application and requires none of the 640K DOS RAM.
-
- * Font selection with 6 different fonts ranging from 8 to 18-point font
- size.
-
-
- B.0 System Requirements
-
- To run the MicroStation Driver your computer system must be capable of
- running your intended application.
-
- * 386 computer with math co-processor
-
- * MicroStation (protected mode) or MicroStation SOLIDS (protected mode).
-
- * A mach64 graphics accelerator board. For dual monitor support,
- you will also need a monochrome graphics board.
-
-
- B.1 Installation for MicroStation Driver
-
- Your Microstation Driver can be easily installed with minimum effort:
-
- 1. Run INSTALL from Disk #1 of the mach64 diskettes.
-
- 2. Select Drivers Installation from the Main Menu.
-
- 2. Choose the 'Microstation' entry.
-
- 3. Follow the instructions as given by the Installation program.
- Use the F1 key to bring up context-sensitive help screens at any
- point in the installation process.
-
-
- C.0 Included Files
-
- The following files are included with the MicroStation 4.0 driver.
-
- README.USD This file in standard ASCII format.
-
- ATIU40R.EXP The executable driver file which is unarchived by INSTALL.EXE
- ATIU40L.EXP into the DRIVERS sub-directory, created by MicroStation when
- MicroStation is installed. The DRIVERS sub-directory is
- located just below the root MicroStation directory
- (C:\USTN40\DRIVERS).
-
- ATIU40R.MA This .MA file is required by MicroStation to interface
- ATIU40L.MA between the protected mode driver ATIU40?.EXP) and the
- MicroStation executable file. This file loads and
- unloads, and handles all calls to the .EXP file at
- MicroStation's request. The .MA file is the file located
- by MicroStation when it reads its CONFIGUR.DAT file,
- located in the C:\USTN40\DATA directory, using the
- MicroStation environment variable MS_PMGRAPH.
- MicroStation only knows how to load a .MA file, not a .EXP
- file, so it is up to the .MA file to load the .EXP.
- ATIU40?.MA file is also unarchived by INSTALL.EXE at the time
- of installation and placed in the DRIVERS sub-directory
- along with ATIU40?.EXP.
-
- ATIU40R.MGL This file is just a text file whose first line contains the
- ATIU40L.MGL line Mach64 MicroStation 4.0, which is displayed by the
- MicroStation USCONFIG program to allow you to select this
- MicroStation 4.0 driver. The .MGL file is uncompressed by
- handled by INSTALL.EXE into the DRIVERS sub-directory along
- with the .MA and .EXP files (all three files should have the
- same name).
-
- ATICFGR.DAT This is the text file created by INSTALL.EXE to be read by
- ATICFGR.DAT ATIU40?.EXP file during driver initialization.
-
- D.0 Technical Notes
-
- D.1 Anti-Aliasing
-
- Anti-aliasing is technical jargon for the process by which graphics
- drivers create the effect of smooth lines on your screen. In normal
- graphics modes most lines exhibit a stair-step effect (jaggies) which
- detracts from the straightness of the line. Anti aliasing "blurs" those
- stair-steps to create the illusion of a straight line.
-
- Lines in standard graphics are a single pixel (screen element) wide,
- with that pixel being the actual color of the line. Anti-aliasing draws
- most lines using 2 pixels, with each pixel pair summing to a full
- intensity of the desired color, visually. In this way, the eye is fooled
- into seeing two pixels as only one, at some position midway between the
- two anti-aliased ones.
-
- Anti-aliasing is accomplished by using the palette entries (colors)
- above color 15 (16-255) to store graded shades of the first 16 colors (0-
- 15) compared to the background color. The graded shades of these 16
- color are computed and loaded automatically by the driver once
- MicroStation communicates the base 16 colors and the background color to
- driver. The background color is user set with the AA_BACKGROUND_COLOR
- option in the ATIUCFG8.DAT file.
-
- By using this graded palette shading technique, the MicroStation driver
- is essentially trading the number of available colors (16 from 256) for
- smooth anti-aliased lines. If you try operating the MicroStation driver
- in anti-aliased mode in a 16 color graphics mode, the MicroStation driver
- will ignore the anti-aliasing and just use the 16 colors available for
- that graphics mode. This is done because the MicroStation driver assumes
- that your graphics board is only capable of 16 simultaneous colors and,
- since anti-aliasing requires at least 256 colors, ignores the anti-
- aliasing mode.
-
- D.2 The USCONFIG.EXE Program
-
- The MicroStation configuration program USCONFIG.EXE, when run, will
- search the DRIVERS sub-directory for all files with the extension .MGL
- and display the first line of each file found as an entry under the
- Vendor Supplied Driver selection menu. If the user picks a .MGL menu
- entry, an initialization program specified by the .MGL file's second line
- (if any) will be executed before continuing.
-
- D.3 The UCONFIG.DAT File
-
- There is a file called UCONFIG.DAT, located in the DATA sub-directory,
- created by MicroStation when User Preferences are saved during a
- MicroStation session. If MicroStation is configured to use a protected
- mode driver, the variable MS_PMGRAPH will be set in the .DAT file to the
- path(s) containing your protected mode driver that exist at the time the
- UCONFIG.DAT file is executed. If you subsequently exit MicroStation and
- reconfigure the display driver for a different protected mode driver,
- MicroStation will not recognize the new configuration unless you change
- the UCONFIG.DAT file. Using a text editor, change the line containing
- the MS_PMGRAPH to point to the new protected mode driver(s). Do not
- delete this file, otherwise you will lose all your other MicroStation
- customizations.
-
- D.4 Becoming an Integral Part of MicroStation
-
- Because the MicroStation Driver is for MicroStation applications only,
- it can become an integral portion of that program and is basically
- transparent to the user. The MicroStation Driver runs in protected-mode
- taking advantage of your 386 computing power. MicroStation Driver is
- not a TSR (terminate and stay resident program) so it does not have to be
- loaded in the valuable lower 640K of RAM that many other programs
- require.
