Detailed Description

A polygon selection highlight style.

SoColorHighlightRenderAction is a render action which renders the scene graph and then renders again the polygons of selected objects in a highlight color.Selected objects are specified by the first SoSelection node in the scene to which this action is applied. A highlight render action can be passed to the setGLRenderAction() method of render area and viewer classes to have an effect on scene graphs.

EXAMPLE

// Scene graph
SoSelection selectionNode  = new SoSelection();
. . .
// Viewer
SoWinExaminerViewer* viewer = new SoWinExaminerViewer();
viewer->setSceneGraph( selectionNode );
 
// Set the highlight render action
viewer->setGLRenderAction( new SoColorHighlightRenderAction() );
 
// Request automatic redraw when selection changes
viewer->redrawOnSelectionChange( selectionNode );
