real value |
Sigma defines the reduction of the radius depending on the surface bending. |
Additional settings for the operator CUT_OFF: |
CUT_OFF_LOW |
= <value> |
real value |
Lower bound of the vector value. All values under this value will be treated as zero. |
CUT_OFF_HIGH |
= <value> |
real value |
Upper bound of the vector value. All values higher than this value will be set to the cut off value. |
