◆ edge_identifier

uint64_t LineartEdge::edge_identifier

Matches the shadow result, used to determine whether a line is in the shadow or not. edge_identifier usages:

Intersection lines: ((e->t1->target_reference << 32) | e->t2->target_reference);
Other lines: LRT_EDGE_IDENTIFIER(obi, e);
After shadow calculation: (search the shadow result and set reference to that);

◆ flags

uint16_t LineartEdge::flags

Also for line type determination on chaining.

◆ intersection_mask

uint8_t LineartEdge::intersection_mask

◆ min_occ

int8_t LineartEdge::min_occ

Definition at line 179 of file MOD_lineart.hh.

◆ object_ref

struct Object* LineartEdge::object_ref

Still need this entry because culled lines will not add to object LineartElementLinkNode node (known as eln internally).

TODO: If really need more savings, we can allocate this in a "extended" way too, but we need another bit in flags to be able to show the difference.

◆ segments

ListBase LineartEdge::segments

Definition at line 178 of file MOD_lineart.hh.

Referenced by lineart_geometry_object_load(), lineart_register_shadow_cuts(), and MOD_lineart_chain_feature_lines().

◆ t1

struct LineartTriangle* LineartEdge::t1

These two variables are also used to specify original edge and segment during 3rd stage reprojection, So we can easily find out the line which results come from.
