Today's question is about size difference. When we get pointlocators via GetClosestLocationsWithinRadius() or other similar methods we alwayse got size problems. When our object have dence geometry and vertexes lies close to each other GetClosestLocationsWithinRadius() method pick vertexes to soon. Even if we provide it with radius 0.01 on a dence mesh it may pick verts from center of polygon. In this case user would try zoom in to get more precise result, but zoom values does not affect GetClosestLocationsWithinRadius() method. Only if he scale up object he would get the result he want.
The good example of how it should work is AddEdgeTool. Even if you have dense mesh this tool works according your current zoom value. If you zoom closer to geo it became more precise. So to mimic this accuracy change i try different approaches: 01. GetClosestLocationsWithinRadius() , filter by radius value. 02. GetRaycastIntersections() , get first and second closest verts , reconstruct CLine representation of closest edge, get vert by parameter value filtering. 03. GetRaycastIntersections() , get first and second closest verts , convert to screen space , reconstruct CLine representation of closest edge, get vert by parameter value filtering. 04. GetRaycastIntersections() , get first closest vert, get vector length from current intersection with geo and closest vert, filter by vector length value. 05. GetRaycastIntersections() , get first closest vert, convert to screen space , get vector length from current intersection with geo and closest vert, filter by vector length value. All this approaches have the same size problem. I assume that for all this approaches the filter value should be calculated via screen space coordinates. This way we got current component size as it was drawn to screen, in other words we preserve zoom value. But in this case all filtering values also changes and in result we still doesn't calculate zoomed components right.
