| 3 |  |  | .SH NAME | 
| 4 |  |  | trad - graphical user interface to Radiance rad(1) program | 
| 5 |  |  | .SH SYNOPSIS | 
| 6 |  |  | .B trad | 
| 7 |  |  | [ | 
| 8 |  |  | .B rfile | 
| 9 |  |  | ] | 
| 10 |  |  | .SH DESCRIPTION | 
| 11 |  |  | .I Trad | 
| 12 |  |  | is a graphical user interface to | 
| 13 |  |  | .I rad(1), | 
| 14 |  |  | which controls the operation of the basic Radiance scene compiling, | 
| 15 |  |  | rendering and picture filtering programs. | 
| 16 |  |  | Trad also includes links to a few utilities for displaying and | 
| 17 |  |  | converting results, but most of what it does can be done by editing | 
| 18 |  |  | a small text file, called the "rad input file". | 
| 19 |  |  | Scene creation still requires the use of a text or graphical editor, | 
| 20 |  |  | or translation from some external CAD format. | 
| 21 |  |  | .PP | 
| 22 |  |  | .I Trad | 
| 23 |  |  | is based on the Tcl/Tk | 
| 24 |  |  | .I wish(1) | 
| 25 |  |  | "windowing shell" written by John Ousterhout. | 
| 26 |  |  | (See below for instructions on installing this package if you do not | 
| 27 |  |  | have it already.)\0 | 
| 28 |  |  | .PP | 
| 29 |  |  | The | 
| 30 |  |  | .I trad | 
| 31 |  |  | interface divides the rendering problem into seven screens: | 
| 32 |  |  | File, Scene, Zone, Views, Options, Action and Results. | 
| 33 |  |  | The File screen is used to load and save rad input files | 
| 34 |  |  | (a.k.a. project files). | 
| 35 |  |  | The Scene screen is used to name the Radiance input files associated | 
| 36 |  |  | with a particular project. | 
| 37 |  |  | The Zone screen is used to assign | 
| 38 |  |  | .I rad | 
| 39 |  |  | variables specific to the section of the model being rendered. | 
| 40 |  |  | The Views screen is used to define specific views to be rendered and | 
| 41 |  |  | set the picture file names and dimensions. | 
| 42 |  |  | The Options screen is used to adjust rendering quality and other | 
| 43 |  |  | parameters. | 
| 44 |  |  | The Action screen is used to initiate interactive and batch | 
| 45 |  |  | renderings. | 
| 46 |  |  | The Results screen is used to display, convert and print the | 
| 47 |  |  | rendered Radiance pictures. | 
| 48 |  |  | .PP | 
| 49 |  |  | If | 
| 50 |  |  | .I trad | 
| 51 |  |  | is called with no rad input file name on the command line, it will | 
| 52 |  |  | start with the File screen and you must enter a valid project file | 
| 53 |  |  | before you will be allowed to continue. | 
| 54 |  |  | If | 
| 55 |  |  | .I rfile | 
| 56 |  |  | is given, then | 
| 57 |  |  | .I trad | 
| 58 |  |  | attempts to open this file. | 
| 59 |  |  | If no such file exists, | 
| 60 |  |  | .I trad | 
| 61 |  |  | assumes you are creating a new file by this name and goes to the | 
| 62 |  |  | Scene screen so you may identify the appropriate Radiance input files. | 
| 63 |  |  | If the file exists but not all renderings have been finished, | 
| 64 |  |  | .I trad | 
| 65 |  |  | goes first to the Action screen, assuming you will want to do | 
| 66 |  |  | something. | 
| 67 |  |  | If the file exists and all renderings have completed and are | 
| 68 |  |  | up-to-date, | 
| 69 |  |  | .I trad | 
| 70 |  |  | goes to the Results screen so that you may examine the final | 
| 71 |  |  | pictures. | 
| 72 |  |  | .PP | 
| 73 |  |  | .I Trad | 
| 74 |  |  | includes an extensive help facility, which may be accessed either by | 
| 75 |  |  | pressing the "HELP" button and searching through the category and | 
| 76 |  |  | topic menus, or by holding the Control key and | 
| 77 |  |  | pressing the left mouse button on the mysterious | 
| 78 |  |  | widget (i.e. the button, entry window, or list box you are curious | 
| 79 |  |  | about). | 
| 80 |  |  | .SH "INSTALLING TCL/TK" | 
| 81 |  |  | The Tcl/Tk package is available by anonymous ftp from | 
| 82 |  |  | ftp.smli.com (204.153.12.45) in the /pub/tcl directory. | 
| 83 |  |  | (Tcl stands for "Tool Command Language," and is pronounced | 
| 84 |  |  | "tickle".) | 
| 85 |  |  | .I Trad | 
| 86 |  |  | is based on Tk release 4.0, which in turn is based on Tcl release 7.4. | 
| 87 |  |  | Although | 
| 88 |  |  | .I trad | 
| 89 |  |  | uses only the | 
| 90 |  |  | .I wish | 
| 91 |  |  | program from this package, | 
| 92 |  |  | .I wish | 
| 93 |  |  | itself depends on | 
| 94 |  |  | additional Tcl and Tk libraries, and the two toolkits must be | 
| 95 |  |  | compiled one after the other. | 
| 96 |  |  | .PP | 
| 97 |  |  | To compile the Tcl/Tk package, download the files "tcl7.4.tar.Z" and | 
| 98 |  |  | "tk4.0.tar.Z" and uncompress and untar them. | 
| 99 |  |  | Then, follow the instructions in the README file in the tcl7.4/ | 
| 100 |  |  | directory to configure the Makefile for your system and install the | 
| 101 |  |  | software. | 
| 102 |  |  | (Usually, it is best to do this as root or have it done by your | 
| 103 |  |  | system administrator if you do not have root privileges.)\0 | 
| 104 |  |  | Then, do the same in the tk4.0/ directory. | 
| 105 |  |  | .PP | 
| 106 |  |  | .I Trad | 
| 107 |  |  | should run without modification once this is done correctly. |
