15.64.65.7 3-d

- When setting the windows for 3-d plots there is compensation for the viewing distance from the object if SCRD is negative. For the same DISTANCE and positive SCRD a window which is half the size of a normal window will only show half of the view. You may compensate for this effect by changing DISTANCE or SCRD. The effect is similar to what you would see if you, and the window remained in the same position and only the window size changed. The following will plot approximately the data with the same view. TD:SET THREE DISTANCE 100 SCRD 50 TD:SET WINDOW X 1 of 1 Y 1 of 1 TD:HISTOGRAM or ... TD:SET THREE DISTANCE 100 SCRD -50 TD:SET WINDOW X 1 of 2 Y 1 of 2 TD:HISTOGRAM or ... TD:SET THREE DISTANCE 100 SCRD 25 TD:SET WINDOW X 1 of 2 Y 1 of 2 TD:HISTOGRAM The following will show a similar view, but from a more distant perspective: TD:SET THREE DISTANCE 200 SCRD 50 TD:SET WINDOW X 1 of 2 Y 1 of 2 TD:HISTOGRAM Since the size of 2 windows is less than half of a single window the example with 2 windows shows slightly less than 1 window.
