Member Function Documentation

void SoTranslation::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.

Reimplemented in SoShuttle.

References SoNode::VRML1.

void SoTranslation::doAction ( SoAction action) [virtual]

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

Reimplemented from SoNode.

References SoAction::getState(), and translation.

Referenced by callback(), getBoundingBox(), getPrimitiveCount(), GLRender(), and pick().

void SoTranslation::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.

References doAction().

void SoTranslation::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.

References doAction().

void SoTranslation::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.

References doAction().

void SoTranslation::getMatrix ( SoGetMatrixAction action) [virtual]

Action method for SoGetMatrixAction.

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

Reimplemented from SoNode.

References SoGetMatrixAction::getInverse(), SoGetMatrixAction::getMatrix(), SbMatrix::multLeft(), SbMatrix::multRight(), SbMatrix::setTranslate(), and translation.

void SoTranslation::pick ( SoPickAction action) [virtual]

Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

void SoTranslation::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.

References doAction().
