This page contains a few extra VRML nodes, and a bit of information on VRML document server considerations.

FontStyle

This nodes sets preferences for the appearance of text created with the AsciiText node. Again, different browsers will produce different results.

Parameter	Default Value	Data Type
family	SERIF	Enumerated - SANS | SERIF | TYPEWRITER
size	10	Float
style	NONE	Enumerated - BOLD | ITALIC | NONE

Example: Select a sans serif font, bold, size 14.

FontStyle {
	family SANS
	size 14
	style BOLD
}

Info

Because many VRML document servers strip-out comments and white-space before sending the document, comments concerning copyright, author info, or any other "important" data can get lost before sending the document. To overcome this, the Info exists. The string parameter has no effect whatsoever on the world, and can be used for any comment that needs to be transmitted.

Parameter	Default Value	Data Type
string	"<Undefined info>"	String

Example: Send the Author's Name.

Info {
	string "This VRML world was created by Fred"
}

For many reasons, mainly because the nodes are of no importantance to the representation of chemical data, some nodes have been totally unmentioned in this site. For completeness, a list of them appears here.

• Group - similar to Separator, but does not restore states (e.g. material).
• LOD - alters the detail level : distance from eye ratio, which is done automatically by some browsers.
• MatrixTransform - same effect can be acheived by Translation, Rotation, and Scale nodes.
• Normal - Defines a set a normal vectors for use with IndexedFaceSet, IndexedLineSet, and PointSet nodes.
• NormalBinding -Sister of MaterialBinding node.
• ShapeHints - gives browsers "hints" about the shapes described in IndexedFaceSet, IndexedLineSet, and PointSet commands.
• Switch - another sister of the Separator node.
• Texture2 - defines a texture map.
• Texture2Transform - 2D transformation of a texture.
• TextureCoordinate2 - used when mapping textures to shapes created with IndexedFaceSet, IndexedLineSet, and PointSet nodes.
• Transform - combines the Rotation, Scale, and Translation nodes.
• WWWAnchor - gives a hyperlink to another VRML world.
• WWWInline - adds inline VRML objects to your VRML world.

• Many VRML document servers strip-out comments and white-space, so use the Info node to add Copyright or Author information.
• Use the extension .wrl for your VRML files. This is a shortening of the word "world".
• The MIME type for VRML files is "x-world/x-vrml". The MIME major type is "x-world", which is shared with other 3D-world file formats. To distunguish VRML files from othe 3D-world files the MIME minor type "x-vrml" is used.
