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.

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]

For internal use only. Reimplemented from SoShape.

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

For internal use only. Reimplemented from 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 SoNode.
