vector getlocalcurvature(float s, float t)
Returns 0 vector if the object does not have subdivision enabled, or has no displacement shader assigned.
Otherwise, the measured convexity and concavity will be returned in x
and y
components respectively.
s
Parametric S shading value. This should be passed from the s
global variable.
t
Parametric <type> shading value. This should be passed from the t
global variable.
