Method Details [hide private]

__init__(self)
(Constructor)

 

Initialises camera object.

Overrides: object.__init__

getPosn(self)

 

Returns the position coordinate of this camera.

Returns:
Position coordinate of this camera.

setPosn(self, coord)

 

Sets the position coordinate of this camera.

Parameters:
  • coord (iterable of 3 float elements) - New position of this camera.

rotatePosn(self, axis, axisPt)

 

Rotates the camera position about the specified axis.

Parameters:
  • axis (iterable of 3 float elements) - Axis of rotation and angle of rotation ( = axis.norm() radians).
  • axisPt (iterable of 3 float elements) - Axis of rotation is assumed to pass through this point.

rotate(self, axis, axisPt)

 

Rotates the camera position and look-at coordinate about the specified axis.

Parameters:
  • axis (iterable of 3 float elements) - Axis of rotation and angle of rotation ( = axis.norm() radians).
  • axisPt (iterable of 3 float elements) - Axis of rotation is assumed to pass through this point.

getLookAt(self)

 

Returns the coordinate at which this camera is looking.

Returns:
The coordinate being looked-at by this camera.

setLookAt(self, coord)

 

Sets the coordinate at which this camera is looking.

Parameters:
  • coord (iterable of 3 float elements) - New coordinate to be looked-at by this camera.

setZoom(self, factor)

 

Decrease the scale of the projection area by the specified factor. A value greater than 1 is a zoom-in, a value less than 1 is a zoom-out.

Parameters:
  • factor (float) - Zoom multiplier factor > 0.0.

getZoom(self)

 

Returns the zoom factor.

Returns: float
The zoom factor.
