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

Here is an example of how a box highlight can be specified for a particular selection node and viewer:

     // 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 );
