NAME SoAsciiText "" "" { simple 3D text shape node }
INCLUDE nodes/SoAsciiText.h
DESC {
This node defines one or more strings of 3D text. In contrast with
\cSoText2\., 3D text can be rotated, scaled, lighted, and textured,
just like all other 3D shapes. In constrast with
\cSoText3\., this 3D ascii text cannot be extruded.
\p
The text origin is at (0,0,0) after applying the current
transformation. The scale of the text is affected by the \vsize\.
field of the current \cSoFont\. as well as the current transformation.
\p
\cSoAsciiText\. uses the current material when rendering.
Textures are applied to ascii text as follows. On the front
face of the text, the texture origin is at the base point of the
first string; the base point is at the lower left for justification
\kLEFT\., at the lower right for \kRIGHT\., and at the lower center
for \kCENTER\.. The texture is scaled equally in both S and T
dimensions, with the font height representing 1 unit. S increases to
the right on the front face.
}
ENUM Justification {
LEFT "Left edges of all strings are aligned",
RIGHT "Right edges of all strings are aligned",
CENTER "Centers of all strings are aligned"
}
FIELD string {
The text string(s) to display. Each string will appear on its own line.
}
FIELD spacing {
Defines the distance (in the negative y direction) between the base
points of successive strings, measured with respect to the current
font height. A value of 1 indicates single spacing, a value of 2
indicates double spacing, and so on.
}
FIELD justification {
Indicates placement and alignment of strings. With \kLEFT\.
justification, the left edge of the first line is at the (transformed)
origin, and all left edges are aligned. \kRIGHT\. justification is
similar. \kCENTER\. justification places the center of the first
string at the (transformed) origin, with the centers of all remaining
strings aligned under it.
}
FIELD width {
Defines the width of each text string. Each string will be scaled so
that it spans this many units.
}
METHOD "" SoAsciiText() {
Creates an ascii text node with default settings.
}
METHOD "" static SoType getClassTypeId() {
Returns type identifier for this class.
}
ACTION SoGLRenderAction {
Draws text based on the current font, transformation,
drawing style, material, texture, complexity, and so on.
}
ACTION SoRayPickAction {
Performs a pick on the text. The string index and character position
are available from the \cSoTextDetail\..
}
ACTION SoGetBoundingBoxAction {
Computes the bounding box that encloses the text.
}
ACTION SoCallbackAction {
If any triangle callbacks are registered with the action, they will be
invoked for each successive triangle used to approximate the text
geometry.
