Detailed Description

The SoMatrixTransform class is a transformation node.

This class is the most flexible transformation node, as you can use it to accumulate any kind of transformation matrix on top of the current model transformation matrix.

SoMatrixTransform::~SoMatrixTransform  )  [protected, virtual]
 

Destructor.


Member Function Documentation

void SoMatrixTransform::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 SoTransformation.

void SoMatrixTransform::doAction SoAction action  )  [virtual]
 

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

void SoMatrixTransform::callback SoCallbackAction action  )  [virtual]
 

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

void SoMatrixTransform::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 SoNode.

void SoMatrixTransform::getBoundingBox SoGetBoundingBoxAction action  )  [virtual]
 

Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

void SoMatrixTransform::getMatrix SoGetMatrixAction action  )  [virtual]
 

Action method for SoGetMatrixAction.

Updates action by accumulating with the transformation matrix of this node (if any).

Reimplemented from SoNode.

void SoMatrixTransform::pick SoPickAction action  )  [virtual]
 

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

void SoMatrixTransform::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 SoNode.
