Compute the projection along given directions of surface element edges onto target edges.
corners1 | The coordinates of the surface element corners whose edges are projected. |
corners2 | The coordinates of the surface element corners on which is projected. |
directions1 | The directions along which the projection is done. |
gt1 | The geometry type of the projected surface element. |
gt2 | The geometry type of the target surface element. |
polygonCorners | If intersection points are found their local coordinates are added to this vector. |
hitCorners | Vector containing information on which surface element corners are projected on each other. |
neighborIntersects1 | If two edges intersect then the corresponding surface element neighbors also intersect. This information for the projected surface element is stored in the bitfield. |
neighborIntersects2 | If two edges intersect then the corresponding surface element neighbors also intersect. This information for the surface element on which is projected is stored in the bitfield. |
overlap | The amount of overlap that is allowed, i.e. projection among the opposite direction is valid if the scaling is smaller than overlap. |
