Detailed Description

This visitor traverses the scene graph and stores MatrixEstimates on osgAR::Group nodes.

Member Function Documentation

void ErrorVisitor::apply (  osg::Transform &  transform  )  [virtual]

Method to be called for a TRANSFORM

void ErrorVisitor::apply (  osg::Group &  group  )  [virtual]

Method to be called for a GROUP Store the estimate

void ErrorVisitor::handleAutoTransform (  const osg::AutoTransform &  t, const MatrixEstimate &  lme, MatrixEstimate &  me )  [protected]

Because this is some automatically adaptive transformation, set the error basically back to 0

void ErrorVisitor::handleDOFTransform (  const osg::DOFTransform &  t, const MatrixEstimate &  lme, MatrixEstimate &  me )  [protected]

Because this is some automatically adaptive transformation, set the error basically back to 0

void ErrorVisitor::handleOSGARTransform (  const osgExtension::Transform &  transform, const MatrixEstimate &  lme, MatrixEstimate &  me )  [protected]

Handle the OSGAR transformation. Unlike all of the other types of transformations, this type injects *noise* into the scene graph and so is a bit more complicated to handle...

void ErrorVisitor::replaceLocalMatrixEstimate (  osgExtension::MatrixEstimate &  matrixEstimate  )

replace the local matrix estimate

void ErrorVisitor::reset (   )

clears the _estimatePath and pushes the initial value onto the stack
