Field Detail

textureCoordinates

public final Point2F textureCoordinates

The texture coordinates of this Vertex instance.

position

public final Point3F position

The position of this Vertex instance.

normal

public final Vector3F normal

The normal of this Vertex instance.

Constructor Detail

Vertex

public Vertex(Point2F textureCoordinates,
              Point3F position,
              Vector3F normal)

Constructs a new Vertex instance.

If either textureCoordinates, position or normal are null, a NullPointerException will be thrown.

Parameters:

textureCoordinates - the texture coordinates of this Vertex

position - the position of this Vertex

normal - the normal of this Vertex

Throws:

java.lang.NullPointerException - thrown if, and only if, either textureCoordinates, position or normal are null

Method Detail

equals

public boolean equals(java.lang.Object object)

Compares object to this Vertex instance for equality.

Returns true if, and only if, object is an instance of Vertex, and their respective values are equal, false otherwise.

Overrides:

equals in class java.lang.Object

Parameters:

object - the Object to compare to this Vertex instance for equality

Returns:

true if, and only if, object is an instance of Vertex, and their respective values are equal, false otherwise

hashCode

public int hashCode()

Returns a hash code for this Vertex instance.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this Vertex instance

getTextureCoordinates

public Point2F getTextureCoordinates()

Returns the texture coordinates of this Vertex instance.

Returns:

the texture coordinates of this Vertex instance

getPosition

public Point3F getPosition()

Returns the position of this Vertex instance.

Returns:

the position of this Vertex instance

toString

public java.lang.String toString()

Returns a String representation of this Vertex instance.

Overrides:

toString in class java.lang.Object

Returns:

a String representation of this Vertex instance

getNormal

public Vector3F getNormal()

Returns the normal of this Vertex instance.

Returns:

the normal of this Vertex instance

setPosition

public Triangle.Vertex setPosition(Point3F position)

Sets a new position.

Returns a new Vertex with the new position set.

If position is null, a NullPointerException will be thrown.

Parameters:

position - the new position

Returns:

a new Vertex with the new position set

Throws:

java.lang.NullPointerException - thrown if, and only if, position is null

transform

public Triangle.Vertex transform(Matrix44F m)

Transforms this Vertex given the Matrix44F m.

Returns a new Vertex with the transformation performed.

If m is null, a NullPointerException will be thrown.

Parameters:

m - a Matrix44

Returns:

a new Vertex with the transformation performed

Throws:

java.lang.NullPointerException - thrown if, and only if, m is null

translateX

public Triangle.Vertex translateX(float x)

Translates this Vertex in the X-direction.

Returns a new Vertex with the translation performed.

Parameters:

x - the amount to translate this Vertex in the X-direction

Returns:

a new Vertex with the translation performed

translateY

public Triangle.Vertex translateY(float y)

Translates this Vertex in the Y-direction.

Returns a new Vertex with the translation performed.

Parameters:

y - the amount to translate this Vertex in the Y-direction

Returns:

a new Vertex with the translation performed

translateZ

public Triangle.Vertex translateZ(float z)

Translates this Vertex in the Z-direction.

Returns a new Vertex with the translation performed.

Parameters:

z - the amount to translate this Vertex in the Z-direction

Returns:

a new Vertex with the translation performed
