Fields
| Name | Description | |
|---|---|---|
 | mBoundsGlobal | Bounding box to limit search to. If the bounds are all 0, the intersection of the 2 layer sets will be used. |
| mFlags | Flags for operation |
| mMaxDistResMult | Maximum compare distance / resolution multiplier specifying the min required distance when looking for changes. (1.0 for native resolution, negative for resolution in meters, 0.0 to require exact match for no change) |
| mMinNearbyNewCount | Minimum number of nearby 'new points' to require before treating point as new. This allows discarding of isolated new points. (0 to keep all) |
| mNewComparePointsLayer | Handle to new layer holding all points from mQueryNewComparePoints (created if GM_LidarCompare_CreateNewLayers is set) |
| mNewCompareToPointsLayer | Handle to new layer holding all points from mQueryNewCompareToPoints (created if GM_LidarCompare_CreateNewLayers and GM_LidarCompare_CompareBothDirs are set) |
| mNewLayerDesc | Base description to use for new point cloud layers created from the differences. Use NULL for default. |
| mQueryNewComparePoints | Lidar query that will hold all points in 'compare to' set that aren't in the 'compare' set (if GM_LidarCompare_CreateNewQueries is set). Call GM_FreeLidarQuery to free when you are done with this |
| mQueryNewCompareToPoints | Lidar query that will hold all points in 'compare to' set that aren't in the 'compare' set (if GM_LidarCompare_CreateNewQueries and GM_LidarCompare_CompareBothDirs are set). Call GM_FreeLidarQuery to free when you are done with this |
