"Detailed Description" .PP The \fBSoText2\fP class is a node type for visualizing 2D text aligned with the camera plane\&. \fBSoText2\fP text is not scaled according to the distance from the camera, and is not influenced by rotation or scaling as 3D primitives are\&. If these are properties that you want the text to have, you should instead use an \fBSoText3\fP or \fBSoAsciiText\fP node\&. .PP Note that even though the size of the 2D text is not influenced by the distance from the camera, the text is still subject to the usual rules with regard to the depth buffer, so it \fIwill\fP be obscured by graphics laying in front of it\&. .PP The text will be \fIpositioned\fP according to the current transformation\&. The x origin of the text is the first pixel of the leftmost character of the text\&. The y origin of the text is the baseline of the first line of text (the baseline being the imaginary line on which all upper case characters are standing)\&. .PP The size of the fonts on screen is decided from the \fBSoFont::size\fP field of a preceding SoFont-node in the scene graph, which specifies the size in pixel dimensions\&. This value sets the approximate vertical dimension of the letters\&. The default value if no SoFont-nodes are used, is 10\&. .PP One important issue about rendering performance: since the positioning and rendering of an \fBSoText2\fP node depends on the current viewport and camera, having \fBSoText2\fP nodes in the scene graph will lead to a cache dependency on the previously encountered SoCamera-node\&. This can have severe influence on the rendering performance, since if the camera is above the \fBSoText2\fP's nearest parent \fBSoSeparator\fP, the \fBSoSeparator\fP will not be able to cache the geometry under it\&. .PP (Even worse rendering performance will be forced if the \fBSoSeparator::renderCaching\fP flag is explicitly set to \fRON\fP, as the \fBSoSeparator\fP node will then continuously generate and destruct the same cache as the camera moves\&.) .PP \fBSoText2\fP nodes are therefore best positioned under their own \fBSoSeparator\fP node, outside areas in the scene graph that otherwise contains static geometry\&. .PP Also note that \fBSoText2\fP nodes cache the ids and positions of each glyph bitmap used to render \fRstring\fP\&. This means that \fRUSE\fP of a \fRDEF'ed\fP \fBSoText2\fP node, with a different font, will be noticeably slower than using two separate \fBSoText2\fP nodes, one for each font, since it will have to recalculate glyph bitmap ids and positions for each call to \fRGLrender()\fP\&. .PP \fBSoScale\fP nodes cannot be used to influence the dimensions of the rendering output of \fBSoText2\fP nodes\&. .PP \fBFILE FORMAT/DEFAULTS:\fP .PP .nf Text2 { string "" spacing 1 justification LEFT } .fi .PP .PP \fBSee also\fP .RS 4 \fBSoFont\fP, \fBSoFontStyle\fP, \fBSoText3\fP, \fBSoAsciiText\fP .RE .PP .SH "Member Enumeration Documentation" .PP .SS "enum \fBSoText2::Justification\fP" Used to specify horizontal string alignment\&. .PP \fBEnumerator\fP .in +1c .TP \f(BILEFT \fP Left edges of strings are aligned\&. .TP \f(BIRIGHT \fP Right edges of strings are aligned\&. .TP \f(BICENTER \fP Centers of strings are aligned\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoText2::SoText2 (void )" Constructor\&. .SS "SoText2::~SoText2 ()\fR [protected]\fP, \fR [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "\fBSoType\fP SoText2::getClassTypeId (void )\fR [static]\fP" This static method returns the \fBSoType\fP object associated with objects of this class\&. .SS "\fBSoType\fP SoText2::getTypeId (void ) const\fR [virtual]\fP" Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&.
