NAME
SoResetTransform -
The SoResetTransform class is a node type which makes it possible to
’nullify’ state during traversal.
SoResetTransform is useful for setting up geometry in the scene graph
which will not be influenced by the transformation nodes before it
during traversal.
SYNOPSIS

Member Function Documentation
void SoResetTransform::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 SoResetTransform::doAction (SoAction * action) [virtual] This function
performs the typical operation of a node for any action.
Reimplemented from SoNode.
void SoResetTransform::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 SoResetTransform::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 SoResetTransform::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 SoResetTransform::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 SoResetTransform::pick (SoPickAction * action) [virtual] Action method
for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
void SoResetTransform::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.

reset in the state when met during traversal. Default value is
