Abstract
A value is assigned to a layout bound of a first node in a scene graph. The layout bound constitutes a bounding volume for the object corresponding to the node and may be the display properties of the object and a first set of display modifiers for the node but not a second set. A display layout is calculated for a second node in the scene graph based on the value of the layout bound. Then, nodes of the scene graph are rendered to generate a display on a display device according to the calculated display layout. The value of the layout bound may be assignable, creating greater flexibility in controlling layout. Additionally, the value assigned to the layout bound may be changed. In this way, layout of nodes with respect to each other is flexible and visual effects and animations can either be factored into that layout or not.
