final class EmbeddedAreaPlaneConvexSubset
extends AbstractEmbeddedRegionPlaneSubset
implements PlaneConvexSubset, PlaneConvexSubset.Embedded
Internal implementation of
PlaneConvexSubset
that uses an embedded
ConvexArea
to represent the subspace region. This class is capable of
representing regions of infinite size.-

EmbeddedAreaPlaneConvexSubset
EmbeddedAreaPlaneConvexSubset(EmbeddingPlane plane, ConvexArea area) Create a new instance from its component parts.- Parameters:
plane
- plane the the convex area is embedded inarea
- the embedded convex area
-
-
Method Details
-
getEmbedded
Return an object containing the plane subset as an embedded 2D subspace region.- Specified by:
getEmbedded
in interfacePlaneConvexSubset
- Specified by:
getEmbedded
in interfacePlaneSubset
- Returns:
- an object containing the plane subset as an embedded 2D subspace region
-
getSubspaceRegion
Get the embedded subspace region.- Specified by:
getSubspaceRegion
in interfacePlaneConvexSubset.Embedded
- Specified by:
getSubspaceRegion
in interfacePlaneSubset.Embedded
- Specified by:
getSubspaceRegion
in interfaceRegionEmbedding<Vector3D,
Vector2D> - Returns:
- the embedded subspace region
-
getVertices
Get the vertices for the convex subset in a counter-clockwise order as viewed looking down the plane normal. Each vertex in the returned list is unique. If the boundary of the subset is closed, the start vertex is not repeated at the end of the list.It is important to note that, in general, the list of vertices returned by this method is not sufficient to completely characterize the subset. For example, a simple triangle has 3 vertices, but an infinite area constructed from two parallel lines and two lines that intersect between them will also have 3 vertices. It is also possible for non-empty subsets to contain no vertices at all. For example, a subset with no boundaries (representing the full plane), a subset with a single boundary (ie, a half-plane), or a subset with two parallel boundaries will not contain any vertices.
- Specified by:
getVertices
in interfacePlaneConvexSubset
- Returns:
- the list of vertices for the plane convex subset in a counter-clockwise order as viewed looking down the plane normal
-
getBounds
Get aBounds3D
object defining an axis-aligned bounding box containing all vertices for this subset. Null is returned if the subset is infinite or does not contain any vertices.- Specified by:
getBounds
in interfacePlaneSubset
- Returns:
- the bounding box for this instance or null if no valid bounds could be determined
-
toTriangles
Return a list of triangles representing the same subset region as this instance. AnIllegalStateException
is thrown if the subset has infinite size and therefore cannot be converted to triangles. If the subset has zero size (is empty), an empty list is returned.- Specified by:
toTriangles
in interfacePlaneSubset
- Returns:
- a list of triangles representing the same subset region as this instance
-
transform
Return a new hyperplane subset resulting from the application of the given transform. The current instance is not modified.- Specified by:
transform
in interfaceHyperplaneConvexSubset<Vector3D>
- Specified by:
transform
in interfaceHyperplaneSubset<Vector3D>
- Specified by:
transform
in interfacePlaneConvexSubset
- Parameters:
transform
- the transform instance to apply- Returns:
- new transformed hyperplane subset
-
reverse
Reverse the orientation of the hyperplane for this instance, returning the result as a new instance. The returned subset contains the same points but has a reversed orientation.- Specified by:
reverse
in interfaceHyperplaneConvexSubset<Vector3D>
- Specified by:
reverse
in interfacePlaneConvexSubset
- Returns:
- a hyperplane convex subset representing the same region but with the opposite orientation.
-
split
Split this instance with the given hyperplane.- Specified by:
split
in interfaceHyperplaneConvexSubset<Vector3D>
- Specified by:
split
in interfacePlaneConvexSubset
- Specified by:
split
in interfaceSplittable<Vector3D,
HyperplaneSubset<Vector3D>> - Parameters:
splitter
- the hyperplane to split this object with.- Returns:
- result of the split operation
