1. A method for visualizing at least one of (i) a sensor of a measurement device and (ii) sensor signals from the sensor, the measurement device having a space for arranging a workpiece and including at least one of a coordinate measuring machine and a microscope, the sensor and the space being movable relative to one another, the method comprising:
obtaining data relating to a three-dimensional scene that is stationary relative to the space;
based on the data relating to the three-dimensional scene, generating a two-dimensional view image of a portion of the three-dimensional scene, wherein:
the view image has two directions corresponding to its two dimensions;
opposing edges are predefined for the view image with respect to at least one of the two directions; and
a central region of the view image is located between the edges; and
repeatedly:
obtaining two-dimensional sensor information, wherein the two-dimensional sensor information comprises one of a sensor image and a representation of the sensor;
combining the two-dimensional sensor information with the view image to form a two-dimensional output image for display by an image display device; and
in response to relative movement between the sensor and the space:
determining whether, when using the same view image as in a previously generated output image, the two-dimensional sensor information of the central region would extend beyond at least one of the two opposing edges; and
in response to extension beyond at least one of the two opposing edges, generating a new two-dimensional view image from the data relating to the three-dimensional scene,
wherein the new view image captures a portion of the three-dimensional scene that has been displaced in accordance with the relative movement.
