6 MODULES» Clear All: Deletes the Indirect Illumination calculation of the whole scene.» Clear Active: Deletes the Indirect Illumination on the selected geometry.» Subdivision Subdivides geometry to calculate the ambient occlusion more precisely.» Enable: Enables/disables the subdivision mode.» Quality: Enabling the subdivision checkbox causes geometries to be refined duringthe Ambient Occlusion calculation process. Additional vertices are inserted intothe meshes. Thus it is possible to get much more smooth results on the geometry.3 Presets are available:• Low Quality: Subdivide up to 2 times if the difference in intensities betweenthe vertices of an edge is above the intensity threshold• Medium Quality: Subdivide up to 2 times if the difference in intensities betweenthe vertices of an edge or the edge midpoint of the triangle edge isabove the intensity threshold• High Quality: Subdivide up to 4 times if the difference in intensities betweenthe vertices of an edge or the edge midpoint is above the intensity threshold» Minimum edge length: Defines the threshold of the subdivision. If the length ofan edge between two vertices is below the defined value, it won’t be subdividedand no additional vertices will be added.» Intensity threshold: Sets the threshold of intensity values of two vertices, to forcea subdivision of the triangle edge.Caution: Enabling this feature increases calculation time and also increases the polygoncount of the scene.» Calculate ALL Calculates the ambient occlusion for all visible and selected nodesand their childNodes.» Calculate Missing Calculates the ambient occlusion for all missing visible and selectednodes and their childNodes104
