Creates a new Triangle from the Points a, b, and c

Parameters:

a -

b -

c -

Method Detail

getHitsOnBoundingBox

public java.util.ArrayList<PointND> getHitsOnBoundingBox(AbstractCurve other)

Overrides:

getHitsOnBoundingBox in class AbstractShape

getA

public PointND getA()

Returns point a

Returns:

point a

getB

public PointND getB()

Returns point b

Returns:

point b

getC

public PointND getC()

Returns point c

Returns:

point c

intersect

public PointND intersect(StraightLine other)

Overrides:

intersect in class Plane3D

intersect

public java.util.ArrayList<PointND> intersect(AbstractCurve other)

Description copied from class: AbstractShape

Returns the intersection points between the curve and the shape. Returns null, if the intersection is empty.

Overrides:

intersect in class Plane3D

Returns:

the intersection points.

isInTriangle

public boolean isInTriangle(PointND p)

Computes whether the given point is inside of the triangle. Implementation is based on barycentric coordinates.

Parameters:

p - the point

Returns:

true if it is inside of the triangle.

getRasterPoints

public PointND[] getRasterPoints(int number)

Description copied from class: AbstractShape

Rasters the shape with a given number of points or less. If the shape is not bounded null is returned.

Overrides:

getRasterPoints in class Plane3D

Parameters:

number - the number of points

Returns:

the raster points

isBounded

public boolean isBounded()

Description copied from class: AbstractShape

Returns true if the shape is of limited space

Overrides:

isBounded in class Plane3D

Returns:

Boundedness of this shape.

applyTransform

public void applyTransform(Transform t)

Description copied from interface: Transformable

Applies the Transform t to the object.

Specified by:

applyTransform in interface Transformable

Overrides:

applyTransform in class Plane3D

Parameters:

t - the transform to apply to the object.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
