Function:pushVRMLname
From S2PLOT
pushVRMLname
Set the clipping plane expansion factor.
Prototype
void ss2snfe(float expand);
Description
Push the given name onto the VRML "name stack". When VRML data is written, it is written in "groups" with these names. The default group name is "ANON". To view the VRML output, which is written to a file called test.wrl, you will need a suitable VRML viewer for your operating system. VRML output is most useful for incorporating into 3d-PDF documents. See here for examples.
