Package eu.mihosoft.vrl.v3d

Class Polygon

java.lang.Object
eu.mihosoft.vrl.v3d.Polygon
public final class Polygon extends Object
Represents a convex polygon. Each convex polygon has a shared property, which is shared between all polygons that are clones of each other or where split from the same polygon. This can be used to define per-polygon properties (such as surface color).

  • Field Details

    • vertices

      public final List<Vertex> vertices
      Polygon vertices

    • plane

      public final Plane plane
      Plane defined by this polygon. Note: uses first three vertices to define the plane.

  • Constructor Details

    • Polygon

      public Polygon(List<Vertex> vertices, PropertyStorage shared)
      Constructor. Creates a new polygon that consists of the specified vertices. Note: the vertices used to initialize a polygon must be coplanar and form a convex loop.
      Parameters:
      vertices - polygon vertices
      shared - shared property

    • Polygon

      public Polygon(List<Vertex> vertices)
      Constructor. Creates a new polygon that consists of the specified vertices. Note: the vertices used to initialize a polygon must be coplanar and form a convex loop.
      Parameters:
      vertices - polygon vertices

    • Polygon

      public Polygon(Vertex... vertices)
      Constructor. Creates a new polygon that consists of the specified vertices. Note: the vertices used to initialize a polygon must be coplanar and form a convex loop.
      Parameters:
      vertices - polygon vertices
