Building 3D content with a scene graph
Controlling access capabilities
- Each node has its own read and write capabilities
- Usually a separate capability for each attribute of a node
- Node's also inherit parent class capabilities
- Each capability has an upper-case name
- For example, Shape3D capabilities include:
- ALLOW_APPEARANCE_READ
- ALLOW_APPEARANCE_WRITE
- ALLOW_GEOMETRY_READ
- ALLOW_GEOMETRY_WRITE
- ALLOW_COLLISION_BOUNDS_READ
- ALLOW_COLLISION_BOUNDS_WRITE
- Plus capabilities from the parent Node class, including:
- ALLOW_BOUNDS_READ
- ALLOW_BOUNDS_WRITE
- ALLOW_PICKABLE_READ
- ALLOW_PICKABLE_WRITE
- . . . and others
