The properties of the angle measure object are:
 Photorealistic rendering method defines how the geometry is rendered.

Ray Trace  The angle measure and its dimension text is rendered using ray tracing

Scanline  The measure is rendered using scanline method

Post Process  Rendering is done at post processing stage

Pseudo 3D  A special correction is applied to the geometry, to obtain a constant
appearance the same way as in realtime drawing. Thickness and size of the object will appear constant, regardless of
the distance from camera or the viewing angle.

Text Size  The size of numerical digits (per mills of the full image width),
which display the angle

Thickness  The radius of the line used in photorealistic rendering (per mills)

Threshold  Threshold for measure drawing. Angle measures, which are seen
in a very low angle (viewing direction almost parallel to the angle plane) should not be drawn, because the projected angle
looks like a straight line. This threshold controls when clipping occurs. Value 1 draws all angles.

Angle  The current angle
