Scene Workview The Scene Workview is the most commonly used workview for creating new objects, editing their properties, assembling the scene, and laying out the scene graph. The Scene Workview consists of the Nodes pane on the left, the Scene Graph pane on the right, and the Property pane at the bottom. Scene Graph pane Toolbar Nodes pane Window splitters clicking on the Instantiate Selected Type button or by dragging and dropping the type from the Nodes pane to the Scene Graph pane. The supported Node types are geometries of type Block, Cone, Cylinder, Imported, Sphere and Text3D; Lights of type DirectedLight, SpotLight and PointLight; Groups of type Group, Switcher, and LevelOfDetail with other types such as Fog, MaterialNode and RenderNode. The Scene Graph pane displays the scene graph, which shows how the objects are organized in your scene. You can rearrange the objects in a scene graph using the drag and drop method. Note The following types are special in that they cannot have children: Fog, MaterialNode, and RenderNode. Also, the Geometry and Light types are abstract which means they cannot be instantiated. You use their derived types instead. The Property pane is helpful for viewing and changing the properties of an object. The Property pane has four tabs: All – Shows all the properties of the selected object. The properties shown in Red are protected or readonly which means they cannot be changed. Important – Shows the most specific and basic properties of an object which are required to create the object. Property pane Subtype – Shows all the properties that exist in the derived type that don’t exist in its parent. Editable – As the name says, lists all the properties which can be edited. Scene Workview The Nodes pane shows all the Node types, which are the types that can be added to the scene graph, and their instances. Here you can create new objects by You can create custom subtypes of any of the Node types in this Workview, adding properties as necessary. You cannot add or delete properties for the built-in types. You can delete properties that you have added to your custom types.
