Class TrianglePtr

  • public class TrianglePtr
extends java.lang.Object
    Ptr stores a pointer and optionally takes ownership of the value.

    • Constructor Detail

      • TrianglePtr

        public TrianglePtr​(long cPtr,
                   boolean cMemoryOwn)

      • TrianglePtr

        public TrianglePtr()
        Default constructor yielding a NULL-pointer.

      • TrianglePtr

        public TrianglePtr​(Triangle ptr)
        Do not take ownership of ptr.

        ptr can be null.

        The constructor is implicit on purpose.

    • Method Detail

      • getCPtr

        public static long getCPtr​(TrianglePtr obj)

      • delete

        public void delete()

      • deref

        public Triangle deref()
        The pointer stored in the object.

      • __ref__

        public Triangle __ref__()
        Dereferencing operator.

      • getDeref

        public Triangle getDeref()
        Member access operator.

      • equals

        public boolean equals​(Triangle p)

      • isShared

        public boolean isShared()
        check if this Ptr has shared ownership or none
        ownership
        Returns:
        true if Ptr has shared ownership, false if it has no ownership.

      • isNull

        public boolean isNull()
        checks if the pointer is null
        Returns:
        Returns true if the pointer is null

      • getVertex

        public Vector3D getVertex​(long i)
        get vertex at index i

      • set

        public void set​(long i,
                Vector3D d)

      • calcFaceNormal

        public Vector3D calcFaceNormal()
        calculates the face normal of this triangle. It is assumed
        that the triangle vertices are arranged counter clock wise.

      • isInside

        public boolean isInside​(Vector3D x)
        tests wheather the point x is inside the triangle

      • calcArea

        public double calcArea()
        calculate the area of the triangle
        Returns:
        area in m^2

      • applyTransform

        public void applyTransform​(Transform3D t3d)
        apply a transformation to this triangle
        Parameters:
        t3d - [in] transform that is to be applied

      • transform

        public Triangle transform​(Transform3D t3d)
        Returns Triangle transformed by t3d.

      • getTriangle

        public Triangle getTriangle()

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
