With DesignWorkshop 1.5 and later versions, the .rif file is generated automatically during Radiance scene export. This greatly simplifies the scene setup process for Radiance rendering.
The following notes, however, still describe the more complex manual scene setup process required with DesignWorkshop 1.2.
If you are using DesignWorkshop 1.5 with the following instructions, steps 4 and 5 are optional (since the complete .rif file is generated automatically, except for fine-tuning of the "zone of interest"), and in step 7 you should be sure to upload all 3 scene definition files (the .rad, .rif, and .mat files), instead of just 2 for DW 1.2 (which only used the .rad and .rif files).
In DesignWorkshop :
1) Build your 3D model. Think about the daylighting of the space you'll be rendering.
2) For good practice, Set a view for your rendering, and
Save the model before exporting.
3) Export > Radiance project.rad.
The ".rad" file contains the geometry of the model in Radiance format, including the sun
as it was set in DesignWorkshop.
At the same time as the Export > Radiance command creates
this geometry file, it also creates a ".rpict.sh" file, from which you will copy
the viewing parameters for use in the ".rif" Radiance control file. (And finally,
the Export > Radiance command also creates a ".rview.sh" file,
which we won't be using at all with this method. You can throw away the ".rview.sh" file
at any time.)
Note for Power Macintosh Users:4) Using the DW 3D crosshair and the absolute coordinates fields, measure and record the zone of interest, as 6 numbers in order:
The Radiance Export function in DesignWorkshop PPC (v 1.2 through v 1.2.2) is damaged. To successfully export Radiance data on a Power Macintosh, you should upgrade to DesignWorkshop 1.5. As a temporary measure, you can also do Radiance scene export using DesignWorkshop Lite.
In BBEdit Lite :
5) Open project.rpict.sh. Open a copy of "sample.rif". Copying from project.rpict.sh, and pasting into the .rif file, edit the view parameters, base filename (in four places), and zone of interest to match your project. Save the .rif file as " project.rif".
In NCSA Telnet :
6) Log onto a Unix host computer with Radiance installed, using
your own username and password, and create a new directory for your rendering files.
Using Fetch :
7) Log onto the Unix host computer, using your own username
and password, and set your directory to
project using the Mac-style dialog box.
Put the files project.rif and project.rad into the directory
on your Unix host computer.
In NCSA Telnet :
8) Enter the standard command to run the rendering calculation
9) Check the progress of your rendering by listing the most recent part of
the progress file to the screen.
10) When the rendering is done by this method, the Radiance automatically
normalizes the exposure of the image. Convert the normalized image to a PICT file
Using Fetch :
11) Get the project .pict file (a binary file) from your Unix host computer
to your Macintosh. For best results, in the Fetch save file dialog box, set the file type to "PICT" and the creator
to "8BIM" (for Photoshop). (Note--the type and creator codes are case-sensitive.)
In Photoshop :
12) Double-click on the PICT file, or use the Open As...
command to open the PICT file if necessary, and save it as whatever you
prefer.
That's it!
