.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.
