ToolsFramework: - added new USceneSnappingManager::ExecuteSceneHitQuery API function, as well as accompanying FSceneHitQueryRequest/FSceneHitQueryResult structs - added FSceneQueryVisibilityFilter struct which contains ComponentsToIgnore/InvisibleComponentsToInclude lists for snapping queries and provides shared IsVisible() implementation ModelingComponents: - add FLevelObjectsObserver, tracks Actors added/removed to a Level via various editor events - add FSceneGeometrySpatialCache, maintains spatial data structures for known types of mesh-backed PrimitiveComponents, an octree based on their world-space bounding-boxes, and provides various spatial-query functions - ModelingSceneSnappingManager now maintains a FSceneGeometrySpatialCache for a set of Actors/Components it is notified about, and updates the spatial cache if those components are modified or translated. Currently supports Volumes and DynamicMeshComponents. - add ModelingSceneSnappingManager::ExecuteSceneHitQuery implementation, does raycasts into the world (for static mesh components) and FSceneGeometrySpatialCache for Volumes/DMCs - modified ModelingSceneSnappingManager::ExecuteSceneSnapQuery to also do combined query against StaticMeshComponents via world-linetrace, and FSceneGeometrySpatialCache for Volumes/DMCs - add ToolSceneQueriesUtil::FindNearestVisibleObjectHit variants that take a USceneSnappingManager or UInteractiveTool, and do queries via the SceneSnappingManger, instead of directly linetracing into a UWorld ModleingToolsEditorMode: - add FLevelObjectsObserver instance and use it to drive updates to active ModelingSceneSnappingManager #rnx #jira none #preflight 61a664a09a226d9e823ad4c1 #ROBOMERGE-AUTHOR: ryan.schmidt #ROBOMERGE-SOURCE: CL 18339853 in //UE5/Release-5.0/... via CL 18339869 #ROBOMERGE-BOT: STARSHIP (Release-Engine-Staging -> Release-Engine-Test) (v895-18170469) [CL 18339891 by ryan schmidt in ue5-release-engine-test branch]
