Inheritance diagram for SoAsciiText:

List of all members.

## Detailed Description

The SoAsciiText class renders flat 3D text.

The text is rendered using 3D polygon geometry.

This node is different from the SoText2 node in that it rotates, scales, translates etc just like other geometry in the scene. It is different from the SoText3 node in that it renders the text "flat", i.e. does not extrude the fonts to have depth.

Since:
  Inventor 2.1

## Member Function Documentation

void SoAsciiText::initClass | ( | void |  | ) | `[static]`

| Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoShape.

void SoAsciiText::GLRender | ( | SoGLRenderAction * | action | ) | `[virtual]`

| Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoShape.

void SoAsciiText::getPrimitiveCount | ( | SoGetPrimitiveCountAction * | action | ) | `[virtual]`

| Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables. Reimplemented from SoShape.

void SoAsciiText::computeBBox | ( | SoAction * | action,
|  | SbBox3f & | box,
|  | SbVec3f & | center
| ) | `[protected, virtual]`

Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.

void SoAsciiText::generatePrimitives | ( | SoAction * | action | ) | `[protected, virtual]`

The method implements action behavior for shape nodes for SoCallbackAction. It is invoked from SoShape::callback(). (Subclasses should not override SoNode::callback().)

The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.

Implements SoShape.

SoDetail * SoAsciiText::createTriangleDetail | ( | SoRayPickAction * | action,
|  | const SoPrimitiveVertex * | v1,
|  | const SoPrimitiveVertex * | v2,
|  | const SoPrimitiveVertex * | v3,
|  | SoPickedPoint * | pp
| ) | `[protected, virtual]`

Will create triangle detail for a SoPickedPoint. This method will only be called internally, when generatePrimitives() is used for picking (SoShape::rayPick() is not overridden).

This method returns `NULL` in Open Inventor, and subclasses will need to override this method to create details for a SoPickedPoint.

This is not necessary with Coin. Of course, if you choose to override it, it will work in the same way as Open Inventor.

For this to work, you must supply a face or line detail when generating primitives. If you supply `NULL` for the detail argument in SoShape::beginShape(), you'll have to override this method.

Reimplemented from SoShape.

void SoAsciiText::notify | ( | SoNotList * | list | ) | `[protected, virtual]`

| Notifies all auditors for this instance when changes are made. Reimplemented from SoShape.
