VRML_OPEN Procedure
Opens a VRML file and writes out header information consistent with VRML formatting.
Usage
VRML_OPEN[, filename]
Input Parameters
filename—(optional) A string specifying the file in which to write the VRML formatting. (Default: 'wave.wrl')
Keywords
CGI—Writes out http content-type header for a common gateway interface (CGI) script. The format is of the following form:
Content-type: x-world/x-vrml
SceneInfo—Scalar or array of strings of comments about the scene.
StdOut—Directs the output to standard out, rather than to a file.
Title—A scalar string specifying the title of the created VRML world.
Version—A scalar string. If the VRML version is not “1.0 ascii”, then this keywords indicates it: e.g.: Version = '1.1 qf8b'.
Discussion
The VRML_OPEN procedure opens a .wrl file and writes the required header information to the file. VRML_OPEN must precede all other VRML routines, and the file must be closed using VRML_CLOSE.
Example
VRML_OPEN, 'test_vrml.wrl', Title = 'Test VRML' 
VRML_CLOSE
