Member Function Documentation

◆ minRefinementDistance()

void ACG::SceneGraph::GridNode::minRefinementDistance ( double  _distance)

Set the minimum refinement distance.

This is the distance the viewer needs to the grid, when refinement is started. At a distance greater then the given distance, no refinement takes places.

Definition at line 334 of file GridNode.cc.

◆ setOrientation()

void ACG::SceneGraph::GridNode::setOrientation ( unsigned int  _orientation)

Set the plane orientation.

Definition at line 348 of file GridNode.cc.

Member Data Documentation

◆ minRefinementDistance_

double ACG::SceneGraph::GridNode::minRefinementDistance_
private

This is the distance, which the viewer has to the grid at which the grid is shown with minimal refinement ( lowest split count )
