Parameters

• NewtonBody* body - Current body being tested by newton.
• const NewtonCollision* collision - Current body's collision id.
• void* userData - Userdata parameter from NewtonWorldRayCast or NewtonWorldConvexCast.

Return

• 0 to ignore this body from further checks
• 1 to keep this object when performing further processing
