Detailed Description
CC3NodeDrawingVisitor is a CC3NodeVisitor that is passed to a node when it is visited during drawing operations.
This visitor encapsulates the camera's frustum, so that only nodes that are within the camera's field of view will be drawn. Nodes outside the frustum will be culled and not drawn.
Member Function Documentation
| - (void) drawLocalContentOf: | (CC3Node *) | aNode |
Draws the local content of the specified node.
Invoked by the node itself when the node's local content is to be drawn.
This implementation simply double-dispatches back to the node's drawLocalContentWithVisitor:. Subclass may override to enhance or modify this behaviour.
| - (id) initWithFrustum: | (CC3Frustum *) | aFrustum |
Initializes this instance with the specified frustum.
| + (id) visitorWithFrustum: | (CC3Frustum *) | aFrustum |
Allocates and initializes an autoreleased instance with the specified frustum.
Property Documentation
- (CC3Frustum *) frustum [read, write, retain] |
The frustum used to determine if a node is within the camera's view.
- (BOOL) shouldDecorateNode [read, write, assign] |
Indicates whether nodes should decorate themselves with their configured material, textures, or color arrays.
In most cases, nodes should be drawn decorated. However, specialized visitors may turn off normal decoration drawing in order to do specialized coloring instead.
The default initial value is YES.
