Measure

The measure object is displays its length in view windows. You can add measure objects to you scenes to show information about object dimensions.

The properties of the measure object are:

  • Photorealistic rendering method defines how the geometry is rendered. Note that the object must be made rendering-visible using the Gen tab of the property window.
    • Ray Trace - The measure line 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 real-time 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 digits, which display the length. The value is given as per mills of the full view width in Pseudo 3D mode. If Pseudo 3D mode is disabled, the unit is millimeter.
  • Thickness - The radius of the line used in photorealistic rendering(per mills )
  • Arrow Size - The size of the arrow end symbols (per mills)
  • Threshold - Angle threshold for measure drawing. Measure lines, which are seen in a very low angle (viewing direction almost parallel to the measure line) should not be drawn, because the projected line becomes a single dot. This threshold controls when clipping occurs. Value 1 draws all lines regardless of the angle.
  • Length - The current length of the measure
