Constructor Detail

PickPointFrustum

public PickPointFrustum(Frustum frustum,
                        Rectangle rect)

Constructs a new PickPointFrustum from another Frustum and screen rectangle

Parameters:

frustum - frustum to create the PickPointFrustum from

rect - screen rectangle to store with this frustum

Method Detail

contains

public final boolean contains(double x,
                              double y)

Returns true if the specified point is inside the 2D screen rectangle enclosed by this frustum

Parameters:

x - the x coordinate to test.

y - the y coordinate to test.

Returns:

true if the specified point is inside the space enclosed by this Frustum, and false otherwise.

Throws:

IllegalArgumentException - if the point is null.

contains

public final boolean contains(Point point)

Returns true if the specified point is inside the 2D screen rectangle enclosed by this frustum

Parameters:

point - the point to test.

Returns:

true if the specified point is inside the space enclosed by this Frustum, and false otherwise.

Throws:

IllegalArgumentException - if the point is null.

getScreenRect

public Rectangle getScreenRect()

Returns the screenRect associated with this frustum

Returns:

screenRect associated with this frustum

intersects

public final boolean intersects(Rectangle rect)

Returns true if the specified 2D screen Rectangle intersects the space enclosed by this view aligned frustums screen rectangle.

Parameters:

rect - the rectangle to test

Returns:

true if the specified Rectangle intersects the space enclosed by this Frustum, and false otherwise.

Throws:

IllegalArgumentException - if the extent is null.

transformBy

public PickPointFrustum transformBy(Matrix matrix)

Returns a copy of this PickPointFrustum which is transformed by the specified Matrix.

Overrides:

transformBy in class Frustum

Parameters:

matrix - the Matrix to transform this Frustum by.

Returns:

a copy of this Frustum, transformed by the specified Matrix.

Throws:

IllegalArgumentException - if the matrix is null
