Ignacio Vera commented on LUCENE-7906: -------------------------------------- My feel is that there is a min value missing: * high: higher value of the node * low: lower value ofthe node * max: maximum value of the tree * min: (missing) minimum value of the tree. The condition you want to add is: minValue>=min insterad of minValue>=low ... then you discard edges out of scope. > Spatial relationship between Geoshapes > -------------------------------------- > > Key: LUCENE-7906 > URL: https://issues.apache.org/jira/browse/LUCENE-7906 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/spatial3d > Reporter: Ignacio Vera > Assignee: Karl Wright > Attachments: LUCENE-7906.patch > > > Hi, > Working with geosahpes and trying to resolve spatial relationships between > them I came accross a big limitation when trying to solve the relationship > between two geopolygons. This object does not expose the internal structure. > In particular at some point, it is necessary to check if one polygon > intersects the edges of the other polygon which currently is not possible as > edges are not exposed. > To be able to perform such operation it can be several options. The ones I > can think of are: > 1) Expose the edges of the polygon ( and probably the notable points for the > edges) adding getters in the GeoPolygon interface. Easy to implement and > leave users the responsability of coding the spatial relationship. > 2) Extends GeoPolygon interface to extends geoarea and leave the object make > the spatial relationship. > 3) Extends GeoShape interface so all shapes can infer the spatial > relationship with other GeoShapes. > I might be bias as my interest is in 2d Shapes in the unit sphere and there > might be some cases which what I propose cannot be implemented or are againts > the aim of the library. > What do you think? > Cheers, > Ignacio -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
