ViewPoint
 Usage
• ViewPoint is an option for Graphics3D which gives the point in space from which the objects plotted are to be viewed.
Notes
• ViewPoint -> {x, y, z} gives the position of the view point relative to the center of the three-dimensional box that contains the object being plotted. • The view point is given in a special scaled coordinate system in which the longest side of the bounding box has length 1. The center of the bounding box is taken to have coordinates {0, 0, 0}. • Common settings for ViewPoint are:
| {1.3, -2.4, 2} | default setting | | {0, -2, 0} | directly in front | | {0, -2, 2} | in front and up | | {0, -2, -2} | in front and down | | {-2, -2, 0} | left-hand corner | | {2, -2, 0} | right-hand corner | | {0, 0, 2} | directly above |
• Choosing ViewPoint further away from the object reduces the distortion associated with perspective. • The view point must lie outside the bounding box. • The coordinates of the corners of the bounding box in the special coordinate system used for ViewPoint are determined by the setting for the BoxRatios option. • New in Version 1.
