Interface BoundarySource2D

    • Method Detail

      • toTree

        default RegionBSPTree2D toTree()
        Return a BSP tree constructed from the boundaries contained in this instance. This is a convenience method for quickly constructing BSP trees and may produce unbalanced trees with unacceptable performance characteristics when used with large numbers of boundaries. In these cases, alternate tree construction approaches should be used, such as RegionBSPTree2D.PartitionedRegionBuilder2D.
        Returns:
        a BSP tree constructed from the boundaries in this instance

      • linecast

        default java.util.List<LinecastPoint2D> linecast​(LineConvexSubset subset)
        Intersect the given line subset against the boundaries in this instance, returning a list of all intersections in order of increasing position along the line. An empty list is returned if no intersections are discovered.
        Specified by:
        linecast in interface Linecastable2D
        Parameters:
        subset - line subset to intersect
        Returns:
        a list of computed intersections in order of increasing position along the line
      • linecastFirst

        default LinecastPoint2D linecastFirst​(LineConvexSubset subset)
        Intersect the given line subset against the boundaries in this instance, returning the first intersection found when traveling in the direction of the line subset from its start location.
        Specified by:
        linecastFirst in interface Linecastable2D
        Parameters:
        subset - line subset to intersect
        Returns:
        the first intersection found or null if no intersection is found
      • getBounds

        default Bounds2D getBounds()
        Get a Bounds2D object defining the axis-aligned box containing all vertices in the boundaries for this instance. Null is returned if any boundaries are infinite or no vertices were found.
        Returns:
        the bounding box for this instance or null if no valid bounds could be determined
      • of

        static BoundarySource2D of​(LineConvexSubset... boundaries)
        Return a BoundarySource2D instance containing the given boundaries.
        Parameters:
        boundaries - line subsets to include in the boundary source
        Returns:
        a boundary source containing the given boundaries
      • of

        static BoundarySource2D of​(java.util.Collection<LineConvexSubset> boundaries)
        Return a BoundarySource2D instance containing the given boundaries. The given collection is used directly as the source of the line subsets; no copy is made.
        Parameters:
        boundaries - line subsets to include in the boundary source
        Returns:
        a boundary source containing the given boundaries
