Syntax
struct FProximity
Remarks
Edge in a graph of merge candidates, indicating which Decomposition parts could be merged together Note a proximity link does not guarantee that the geometry (or convex hulls) are touching
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bIsValidLink | Whether this merge can be allowed (e.g. has not been ruled out by negative space) |
 |
bool | bPlaneSeparates | Whether the geometry is separated by Plane. |
 |
FIndex2i | Link | |
 |
double | MergedVolume | What the volume of the convex hull would be if we merged these two parts. |
 |
FPlane3d | Plane | The shared plane between the two hulls (because adjacent hulls are formed by planar cuts in the splitting step) Note: Plane becomes invalid in the merge-up phase; it is used to accelerate filtering in the split-down phase |
