Type

point

Returns

A three-dimensional direction formed from a plan angle and an angle of elevation.

Parameters

• <angle1>
  The plan angle (0 is East). The value is assumed to be in the current angle_mode units.

• <angle2>
  The angle of elevation (90 is Up). The value is assumed to be in the current angle_mode units. If omitted, the value of zero is assumed.

Examples

The following yields the value (0,1,0)

point dir = adir3d(90)
