    • isClockwiseInXZ

      public static boolean isClockwiseInXZ(Vec3D a, Vec3D b, Vec3D c)

    • isClockwiseInYZ

    • closestPointOnSurface

      public Vec3D closestPointOnSurface(Vec3D p)
      Computes the the point closest to the current vector on the surface of triangle abc. From Real-Time Collision Detection by Christer Ericson, published by Morgan Kaufmann Publishers, Copyright 2005 Elsevier Inc
      Returns:
      closest point on triangle (result may also be one of a, b or c)

    • computeCentroid

      public Vec3D computeCentroid()

    • computeNormal

      public Vec3D computeNormal()

    • containsPoint

      public boolean containsPoint(ReadonlyVec3D p)
      Checks if point vector is inside the triangle created by the points a, b and c. These points will create a plane and the point checked will have to be on this plane in the region between a,b,c (triangle vertices inclusive).
      Specified by:
      containsPoint in interface Shape3D
      Returns:
      true, if point is in triangle.

    • flipVertexOrder

      public Triangle3D flipVertexOrder()

    • fromBarycentric

      public Vec3D fromBarycentric(ReadonlyVec3D p)

    • getBoundingBox

      public AABB getBoundingBox()

    • getClosestPointTo

      public Vec3D getClosestPointTo(ReadonlyVec3D p)
      Finds and returns the closest point on any of the triangle edges to the point given.
      Parameters:
      p - point to check
      Returns:
      closest point
