Maximum Edge Length
List of: Discussion Topic
Subjects: Faceting
Contents: Faceter


The edge length is the length of a facet edge. The maximum edge length value allows the facet edge length to be within the specified limit. This is the only way to subdivide facets further in planer faces.


The set_max_edge_length method from the REFINEMENT class specifies the maximum length of a side of a cell in object space. Since a facet cannot be larger than the cell, this determines the maximum size of the facet. If the value is zero, maximum edge length is not considered in faceting.


Figure 1-5 illustrates two cases of maximum edge length. The refinement values are specified in Table 1-4.
