**Hello fellow Unity Developers,**
I am attempting to create a C# function that linearly interpolates a Rigidbody’s drag based upon the *percentage of the Rigidbody’s collider that is within a trigger collider* "Water Region".
**Considerations:**
- Water Regions will likely be
convex and with relatively simple
geometry, but they may sometimes be
spherical and may not always be regular
or quadrilateral.
- The Rigidbody may enter the Water
Region from any point and may be
facing any direction while doing so.
While I am certain such is possible via a series of *Bounds.Contains()* checks, this would not be performant and would have a resolution limited by the number points being checked.
Is there an efficient or mathematical means of determining what percentage of a Collider is within a trigger zone?
Even partial solutions are absolutely welcome (eg: only works with rectangular / spherical Water Regions).
**My absolute gratitude in advance!**
