Interface BoundarySource3D

    • Method Detail

      • toTree

        default RegionBSPTree3D 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 RegionBSPTree3D.PartitionedRegionBuilder3D.
        Returns:
        a BSP tree constructed from the boundaries in this instance
        See Also:
        RegionBSPTree3D.partitionedRegionBuilder()

      • toTriangleMesh

        default TriangleMesh toTriangleMesh​(org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)
        Construct a triangle mesh from the boundaries in this instance.
        Parameters:
        precision - precision context used in boundaries generated by the resulting mesh
        Returns:
        a triangle mesh representing the boundaries in this instance
        Throws:
        java.lang.IllegalStateException - if any boundary in this boundary source is infinite

      • triangleStream

        default java.util.stream.Stream<Triangle3D> triangleStream()
        Return the boundaries of this instance as a stream of Triangle3D instances. An IllegalStateException exception is thrown while reading from the stream if any boundary cannot be converted to a triangle (i.e. if it has infinite size).
        Returns:
        a stream of triangles representing the instance boundaries
        See Also:
        PlaneSubset.toTriangles()

      • linecast

        default java.util.List<LinecastPoint3D> linecast​(LineConvexSubset3D subset)
        Intersect the given line convex subset against the boundaries in this instance, returning a list of all intersections in order of increasing distance along the line. An empty list is returned if no intersections are discovered.
        Specified by:
        linecast in interface Linecastable3D
        Parameters:
        subset - line subset to intersect
        Returns:
        a list of computed intersections in order of increasing distance along the line

      • linecastFirst

        default LinecastPoint3D linecastFirst​(LineConvexSubset3D subset)
        Intersect the given line convex subset against the boundaries in this instance, returning the first intersection found when traveling in the direction of the line subset from its start point.
        Specified by:
        linecastFirst in interface Linecastable3D
        Parameters:
        subset - line subset to intersect
        Returns:
        the first intersection found or null if no intersection is found

      • getBounds

        default Bounds3D getBounds()
        Get a Bounds3D object defining the axis-aligned box containing all vertices in the boundaries for this instance. Null is returned if any boundary is infinite or no vertices are found.
        Returns:
        the bounding box for this instance or null if no valid bounds could be determined

      • of

        static BoundarySource3D of​(PlaneConvexSubset... boundaries)
        Return a BoundarySource3D instance containing the given boundaries.
        Parameters:
        boundaries - boundaries to include in the boundary source
        Returns:
        a boundary source containing the given boundaries

      • of

        static BoundarySource3D of​(java.util.Collection<PlaneConvexSubset> boundaries)
        Return a BoundarySource3D instance containing the given boundaries. The given collection is used directly as the source of the boundaries; no copy is made.
        Parameters:
        boundaries - boundaries to include in the boundary source
        Returns:
        a boundary source containing the given boundaries
