Enable Tangent Diff Interp Scale: If this flag is enabled, th e system will
scale the number of interpola te d vertices based on the difference in the
tangents of neig h boring particles. Each pair of neighboring p articles will
compute the following CheckTangent value:

Scale Distance Tessellation Step Size.
This wil l map so tha t from parallel to orthogonal (0 to 90 degrees) will
scale from 0 to 1. Anything greater than 90 degrees will clamp a t a scale
of 1.
Tang ent Tessellation Scalar: The tangent scal ar for tessellation. Angles be-
