Final answer:
The statement that intersection depends only on the underlying curves traced by r1 and r2 and collision depends on the actual parameterization is false.
Step-by-step explanation:
Collision and intersection of curves depend on both the underlying curves traced by r1 and r2 as well as the actual parameterization. While intersection focuses on the common points between the curves, collision involves the behavior of the curves when they collide.
Therefore, the statement that intersection depends only on the underlying curves traced by r1 and r2 and collision depends on the actual parameterization is false.
