.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. |

27 |
|
|
have it already.)\0 |

|
.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). |

.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. |
