Rendering Multiple Views
See sample ~.rif file for reference. Basically, to render one model
from several viewpoints, simply add additional "view =" lines to the ~.rif file. Radiance will
automatically render the views one after another, reusing as much information as it can
from one the next. The base file name used is based on "PICTURE =".
Rendering a Walkthrough-type Animation using Multiple Views
To efficiently create a high-value Radiance animation from a DesignWorkshop® model, set up and Set each of the sequenctial views. Use Export > Radiance to create the ~.rad geometry file, and the ~.rpict.sh file from which to extract the view parameter for the first "view =" line. Then, Select All, and Hide the entire model. Go to each of your saved views, in order, and Export > Radiance, using a sequential number for the base file name. (A redundant ~.rad file will be created for each Export > Radiance, but by hiding the model before exporting, the redundant files will be very small.) Then open all the ~.rpict.sh files, and Copy and Paste the view parameters from each into a new "view =" line in the ~.rif file. Run the rendering calculation, convert the final "~_#.pic" images all to PICT format, and Fetch all the PICT images to your Macintosh. Finally, use a QuickTime utlility like Convert to Movie to build the image files together into a QuickTime movie.
Rendering Orthographic Views
For a summary of the preset orthographic views available in Radiance, see the lower portion of the sample ~.rif file. Any of these views can be rendered using the sample ~.rif file just by commenting out the upper, perspective-oriented "view =" line, and then in the lower part of the file, uncommenting the "view =" line for the one or more orthographic views you wish to render.
When rendering orthographic views, the values given in "ZONE =" determine a viewbox for the extents of the rendering.
If "ZONE =" exterior, then the viewbox will be rendered as if from infinitely far away, generating an elevation view, and also showing any landscape in front of the elevation.
If "ZONE =" interior, the scene will be rendered as if the model has been sectioned at the front plane of the viewbox. This allows you to render sections, or, by carefully locating the front sides of the viewbox just in front of the building, you can render an elevation while leaving out landscape that might block the view of the building facade.
