C.a.R. > Applications > Graphics > Vanishing Point
An application of Z.u.L. to display the vanishing point. The picture is from a digital camera and imported to C.a.R. as background. Some parallel lines were constructed, meeting in a vanishing point on the horizon.
Two images were exported and mounted to an animated GIF in Photoshop ImageReady. Alternatively, the animation below could have been realized as a C.a.R. applet.
Note that there might be problem, if the camera has some distortion. You need to remove this distortion with a tool like Photoshop or FixFoto.
