Constructor Detail

RMTransform3D

public RMTransform3D()

Creates a transform3d with the identity matrix.

Method Detail

multiply

public RMTransform3D multiply(RMTransform3D aTransform)

Multiplies receiver by given transform.

translate

public RMTransform3D translate(double x,
                               double y,
                               double z)

Translates by given x, y & z.

rotateX

public RMTransform3D rotateX(double anAngle)

Rotate x axis by given degrees.

rotateY

public RMTransform3D rotateY(double anAngle)

Rotate y axis by given degrees.

rotateZ

public RMTransform3D rotateZ(double anAngle)

Rotate z axis by given degrees.

rotate

public RMTransform3D rotate(RMVector3D anAxis,
                            double anAngle)

Rotate about arbitrary axis.

rotate

public RMTransform3D rotate(double rx,
                            double ry,
                            double rz)

Rotate x,y,z with three Euler angles (same as rotateX(rx).rotateY(ry).rotateZ(rz))

worldAlign

public RMTransform3D worldAlign(RMPoint3D originPt)

Returns a matrix whose axes are aligned with the world (screen) coordinate system. All rotations & skews are removed, and perspective is replaced by uniform scaling.

skew

public RMTransform3D skew(double skx,
                          double sky)

Skew by the given degrees.

perspective

public RMTransform3D perspective(double d)

Apply perspective transform.

invert

public RMTransform3D invert()

transform

public RMPoint3D transform(RMPoint3D aPoint)

Transforms a given point (and returns it as a convenience).

transform

public RMVector3D transform(RMVector3D aVector)

Transforms a given vector (and returns it as a convenience).

toArray

public double[][] toArray()

Returns a float array for the transform.

fromArray

public RMTransform3D fromArray(double[][] m2)

Loads the transform flom a float array.

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
