TriangleF

public TriangleF(TriangleF f)

copy constructor

Parameters:

f - [in] - The face that is to be copied.

Method Detail

getCPtr

public static long getCPtr(TriangleF obj)

delete

public void delete()

getVertex

public Vector3Df getVertex(long i)

get vertex at index i

calcFaceNormal

public Vector3Df calcFaceNormal()

calculates the face normal of this triangle. It is assumed
that the triangle vertices are arranged counter clock wise.

isInside

public boolean isInside(Vector3Df 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(Transform3Df t3d)

apply a transformation to this triangle

Parameters:

t3d - [in] transform that is to be applied

transform

public TriangleF transform(Transform3Df t3d)

Returns Triangle transformed by t3d.

getTriangle

public TriangleF getTriangle()
