Converting Solution Files to VRML Files Using LS2VRML
You can use the ls2vrml utility to convert a Lightscape Solution file (.ls) to a VRML version 1.0c file. The ls2vrml
utility syntax is shown in the following example:
ls2vrml [options] solution_file
To use the ls2vrml utility:
1.
Choose Start | Programs | MS-DOS Prompt.
A DOS shell appears.
2.
At the command line, type the following, then press Enter:
CD “\PROGRAM FILES\LIGHTSCAPE\BIN”
Note: (f the path to the Lightscape application files differs from the above, enter it instead then press Enter.
3.
Using the following syntax, type a command at the command line, then press Enter:
ls2vrml [options] solution_file
The Lightscape Solution file is converted to a VRML version 1.0c file.
Note: You can also use a batch file to create a sequence of commands. For instance, you could create ray-
traced image files from multiple Lightscape Solution files.
LS2VRML Options
The following table describes the options available for this utility:
txtr.jpg The name for the generated texture files, combined with an incremental three-digit
number for each successive file.
Option: Extension: Description:
-a Include active layers only.
-bf n1,n2,n3 ... Hierarchy subdivision branching factors. Must be integers which are greater
than or equal to 2. Lightscape uses the subdivision when creating inline nodes.
It initially subdivides the model into a 3D grid n

. The system associates
surfaces that fall completely within a grid node with that node. Grid nodes
themselves can be further subdivided into n

subnodes and so on. The
default is one level. For more information, see “Exporting VRML Files” on page
245.
-c Do not compact file. The default is to compact the VRML file, resulting in
smaller file sizes at the expense of some precision and readability.
