Batch Processing Utilities
How to use the batch processing
utilities included with Lightscape.
This appendix describes the utilities that you can use to increase your
productivity in Lightscape.
Summary
In this appendix, you learn about:
• Processing radiosity solutions using lsrad
• Ray tracing Solution files using lsray
• Rendering files using lsrender
• Converting radiosity meshes to textures using
lsm2t
• Performing batch processing
• Converting Solution files into VRML files using
ls2vrml
• Merging Lightscape files using lsmerge
• Converting DXF files into Preparation files using
dxf2lp
• Converting 3DS files into Preparation files using
3ds2lp
•
Ray tracing Solution files using lsrayf
• Deleting files using lspurge
•
Creating batch files.
For information on using the luminous intensity
distribution (LID) conversion utilities (LID2CIBSE,
LID2IES, and LID2LTLI), see Chapter 9,
“Photometrics.”
Processing Radiosity Solutions
Using LSRAD
Use the lsrad utility to process a radiosity solution.
Although it is possible to process a radiosity solution
in Lightscape, lsrad is more efficient because the
model is not displayed after each iteration. The lsrad
utility syntax is shown in the following example:
lsrad [options] filename
The input to the lsrad program can be either a Prep-
aration file (.lp) or a Solution (.ls) file. In the case of
the Preparation file, the data is initiated first and the
