 ## Adding New Collision Data Structures
 
-When implementing other bounding volume classes and intersection tests, you will probably need to add a custom content pipeline processor. For example, your game might need to use convex hulls for collision detection. You could use a custom processor to determine the convex hull and then place it in the model's tag field. Then, when the model is loaded at run time, the convex hull information would be available in the model. For more information, see [Extending a Standard Content Processor](Content_Pipeline/HowTo_Extend_Processor.md).
