- Method Detail
  - getLocalExtent
```
Box getLocalExtent(ColladaTraversalContext tc)
```
    Returns this renderable's model coordinate extent.
    
    Parameters:
    
    tc - The traversal context to use when determining the extent.
    
    Returns:
    
    The model coordinate extent.
    
    Throws:
    
    java.lang.IllegalArgumentException - if either the traversal context is null.
  - preRender
```
void preRender(ColladaTraversalContext tc,
               DrawContext dc)
```
    Pre-Render this element.
    
    Parameters:
    
    tc - the current COLLADA traversal context.
    
    dc - the current draw context.
    
    Throws:
    
    java.lang.IllegalArgumentException - if either the traversal context or the draw context is null.
  - render
```
void render(ColladaTraversalContext tc,
            DrawContext dc)
```
    Render this element.
    
    Parameters:
    
    tc - the current COLLADA traversal context.
    
    dc - the current draw context.
    
    Throws:
    
    java.lang.IllegalArgumentException - if either the traversal context or the draw context is null.
