5.2 Edit» Unsplit Geometries with one Triangle Merges all triangles which are childrenof the selected node. This function is much faster than the merge geometryfunction. CRTL + SHIFT + T.» Subdivide Geometry Subdivides the selected geometry into more triangles resultingin a finer mesh. A dialogue box opens.» Subdivision Mode: You have the following choices:• Standard: Each polygon is subdivided until the the edge lengths fall belowthe max edge length value.• Phong Interpolation: Each edge of a polygon is subdivided right in its centerand the position of the new vertices is calculated by means of phong interpolation.The results are smooth surfaces which also redefine the silhouettes.Caution: In some cases hard edges produce gaps in the geometry.» Iterations: This attribute describes the amount of interations used for phonginterpolation. The value ’1’ generates 4 triangles per triangle, ’2’ generates 16triangles per triangle, ’3’ generates 64 triangles per triangle and ’4’ generates 256triangles per triangle.» Max edge length: This value describes the maximum edge length threshold, underwhich an edge is not subdivided anymore.» Group by Material Groups the Scenegraph’s objects by assigned materials.Caution: The whole Scenegraph structure will be rearranged.» Group Selection Groups selected objects. A new group node will be createdand all 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 raise the render performance. All optimizationprocesses will be applied to the selected nodes and their children.73
