Methods

beginPan(u, v)None:

Begin a pan at at the given u and v.

m.beginPan(.1, .2)

beginRotate(u, v)None:

Begin an arcball rotation at the given u and v.

m.beginRotate(.1, .2)

beginDolly(u, v)None:

Begin a dolly at at the given u and v.

m.beginDolly(.1, .2)

pan(u, v)None:

Pan the view by the given x and y.

m.pan(.1, .2)

panTo(u, v, scale=1.0)None:

Pan from the u,v given in the last call to beginPan() to the given u and v, applying a scale as well to the pan amount.

  • scale - (Keyword, Optional) Scale the operation by this amount.
m.panTo(.1, .2)

rotateTo(u, v, scale=1.0)None:

Rotates the arcball to the given u and v position.

  • scale - (Keyword, Optional) Scale the operation by this amount.
m.rotateTo(.1, .2)

dolly(z)None:

Dolly the view by the given z value.

m.dolly(.3)

dollyTo(u, v, scale=1.0)None:

Dolly from the u,v given in the last call to beginDolly() to the given u and v, applying a scale as well to the dolly amount.(Keyword, Optional)

  • scale - Scale the operation by this amount.
m.dollyTo(.1, .2)

transform()tdu.Matrix:

Gets the current transform matrix for the arcball.

m.transform()

setTransform(matrix)None:

Sets the current transform matrix for the arcball. Scales in the given matrix will be ignored.

m.setTransform(m)

identity()None:

Resets all values of the ArcBall to the default state.

m.identity()
