EYE DIRECTION Control

      

The command EYE DIRECTION allows the user to specify the direction of sight to the model. A `from' and `to' pair of model co-ordinate triplets may be given to define the line of sight. If no `to' co-ordinate position is given then the `to' position is taken as the origin of the model.

Examples:

1.

EYE DIRECTION 100 20 20

A line of sight is defined from co-ordinates X=100, Y=20, and Z=20 in model space to the model origin.

2.

EYE DIRECTION 100 20 20 300 0 0

A line of sight is defined in model space from co-ordinates X=100, Y=20, and Z=20 to co-ordinates X=300, Y=0, Z=0 .
