// Class : TextNode
|
|
// Description : The primary interface to this module. This class
|
|
// does basic text assembly; given a string of text and
|
|
// a TextFont object, it creates a piece of geometry
|
|
// that may be placed in the 3-d or 2-d world to
|
|
// represent the indicated text.
|
|
//
|
|
// The TextNode may be used in one of two ways.
|
|
// Naively, it may simply be parented directly into the
|
|
// scene graph and rendered as if it were a GeomNode; in
|
|
// this mode, the actual polygon geometry that renders
|
|
// the text is not directly visible or accessible, but
|
|
// remains hidden within the TextNode.
|
|
//
|
|
// The second way TextNode may be used is as a text
|
|
// generator. To use it in this way, do not parent the
|
|
// TextNode to the scene graph; instead, set the
|
|
// properties of the text and call generate() to return
|
|
// an ordinary node, containing ordinary geometry, which
|
|
// you may use however you like. Each time you call
|
|
// generate() a new node is returned.
