l, | |||
UseExisting = 0 , |

|||
) |
Defines "LocalLength" hypothesis to cut an edge in several segments with the same length.
l | for the length of segments that cut an edge |
UseExisting | if ==true - searches for an existing hypothesis created with the same parameters, else (default) - creates a new one |
p | precision, used for calculation of the number of segments. The precision should be a positive, meaningful value within the range [0,1]. In general, the number of segments is calculated with the formula: nb = ceil((edge_length / l) - p) Function ceil rounds its argument to the higher integer. So, p=0 means rounding of (edge_length / l) to the higher integer, p=0.5 means rounding of (edge_length / l) to the nearest integer, p=1 means rounding of (edge_length / l) to the lower integer. Default value is 1e-07. |
