Houdini 19.0 Expression functions degree

degree expression function

Returns the degree a specified face or hull.

degree(surface_node, prim_num, D_U|D_V)

Polygons and meshes are expressed as linear functions, so their degree is 1. Spline types – NURBS and Bezier curves and surfaces – have degrees ranging from 1 to 10.


If the primitive is a polygon or a curve, D_U and D_V are irrelevant.
