Architecture 410/510 - Matthews

R a d i a n c e Quick Start Notes

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.

3) Export > Radiance project. r a d.

Note for Power Macintosh Users: 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 need to use the Universal version of DesignWorkshop 1.1. (Because of the different internal number formats, regular DesignWorkshop 1.1 won't work on a Power Mac.) The universal version is available free on request to all registered owners of DesignWorkshop, from Artifice, Inc., 541-345-7421, 1342 High Street, Eugene, Oregon.
4) Using the DW 3D crosshair and the absolute coordinates fields, measure and record the zone of interest, as 6 numbers in order:
Xmin, Xmax, Ymin, Ymax, Zmin, Zmax.

In BBEdit Lite

5) Open project.r Open a copy of "sample.rif". Copying from project, 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. r i f".

In NCSA Telnet

6) Log onto "", using your own username and password, and create a new directory for your rendering files.
mkdir project

Then move to that directory
cd project

Using Fetch

7) Log onto "", using your own username and password, and set your directory to project using the Mac-style dialog box. Put the files project. r i f and project. r a d into the directory on Darkwing.

In NCSA Telnet

8) Enter the command to run the rendering calculation
nice rad project .rif &

9) Check the progress of your rendering
tail progress

10) When the rendering is done, it automatically normalizes the image. Convert the normalized image to a PICT file
ra_pict project _1.pic project . pict

Using Fetch

11) Get the project .pict file (a binary file) from Darkwing 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!

Example Simple Image

Example .rif file -- Basic

# improved typical rif file--950403.kmm
# for running Radiance using the "rad" command
# with view extracted from DW exported
# and with zone x min, max y min, max z min, max
# determined manually in DW for the DW scene
