Method Detail

pointToSphere

public static javafx.geometry.Point3D pointToSphere(double x,
                                                    double y,
                                                    double sphereRadius)

Maps canvas coordinate to a spherical location.

Parameters:

x - canvas x coordinate

y - canvas y coordinate

Returns:

x/y location mapped onto sphere

lookAt

public static javafx.scene.transform.Affine lookAt(javafx.geometry.Point3D target,
                                                   javafx.geometry.Point3D pos,
                                                   javafx.geometry.Point3D yUp)

Computes a matrix to orient a node towards a given point, defined by target.

Parameters:

target - the target to look at

pos - the viewer's current location

yUp - the direction of "up"

Returns:

affine transform that orients towards the target
