Main description of graphics properties within an
A3DGraphicsDatastructure serves as an entry point for describing all the graphics properties of an
The structure mainly serves as a container for a style index, defined with
m_uiStyleIndex. This value is used within
A3DGlobalGetGraphStyleDatato fill in a
Objects can be organized by assigning them into layers. All the items inside a same layer are treated as a group. A layer is a numeric identifier which is set with
m_uiLayerIndex. When no specific layer is set,
m_usBehaviourdescribes the propagation policy for the graphics properties of the object within a model file.
As initializing the structure is done by calling
A3D_INITIALIZE_DATA, the operation will set all the fields to zero. The initial value of
m_usBehaviourwill thus hide the object from display.
