struct PK_EDGE_repair_o_s { int o_t_version; --- version number of option structure PK_LOGICAL_t ensure_on_surfs; --- ensure edges lie on surfaces --- (default PK_LOGICAL_true) double max_tolerance; --- maximum tolerance allowed for --- above option (default 1.0e-5). }; typedef struct PK_EDGE_repair_o_s PK_EDGE_repair_o_t; This options structure holds optional controls for PK_EDGE_repair. Description of fields: ensure_on_surfs Ensure that each edge lies on its adjacent surfaces, by setting an appropriate tolerance on the edge, if necessary. max_tolerance The maximum tolerance which may be set when the previous option is selected. The function will fail if it cannot make the edges lie on their surfaces by using a tolerance of at most max_tolerance.
