Detailed Description

Velocity constraint point.

Note

Default initialized to values that make this point ineffective if it got processed counter to being a valid point per the point count property. This allows both points to be unconditionally processed which may be faster if it'd otherwise cause branch misprediction and depending on the cost of branch misprediction.

This structure is at least 36-bytes large.
