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.

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'
