5 SCENEGRAPH» Subdivision Mode: You have the following choices:• Standard: Each polygon is subdivided until the edge lengths fall below themaximum edge length threshold.• Phong Interpolation: Each edge of a polygon is subdivided right in itscenter and the position of the new vertices is calculated by means of phonginterpolation. The results are smoother surfaces which also redefine thesilhouettes. Caution: In some cases, hard edges result in gaps in thegeometry.» Iterations: This attribute describes the number of iteration used for phong interpolation.The value ’1’ generates 4 triangles per triangle, ’2’ generates 16triangles per triangle, ’3’ generates 64 triangles per triangle and ’4’ generates256 triangles per triangle.» Max edge length: This value describes the maximum edge length threshold,below which an edge is no longer subdivided.» Group by Material Groups the objects of the Scenegraph by assigned materials.Caution: The whole Scenegraph structure will be rearranged.» Group Selection Groups selected objects. A new group node will be created andall selected objects will be attached as children to the new node.» Show Optimize Module Opens the Optimize Module. The optimize functionshelp to optimize the scene and thereby increase the rendering performance. Alloptimization processes will be applied to the selected nodes and their children.5.3 Convert To» Group Converts the selected node to a Group node.» Matrix Transform Converts the selected node to a Transform node.82
