Depth perception on

Depth perception gives the appearance to the scene that the further an object is away from the viewer the darker it may become. Any Object which has been drawn may have graphics depth applied to it.

To run this function: Choose View > Surface view options > Depth perception on

Firstly, the minimum, maximum and centre of data is calculated across all graphics layers. It uses the current camera viewing angle and distance to determine the best appearance possible for the data. These values may be modified to allow freedom when the data does not appear correctly shaded. These values must always be recalculated when adding new data or loading new files into graphics.
