1.  Introduction

Radius variation plot graphics is used in most reports for stone symmetry indication:

On X axis azimuth is shown.

On Y axis deviation is shown.

MIC is the radius of the maximum circle that may be inscribed.

Girdle center mass is used as the center of a model.

2. Red curve line calculations

  1. Draw plane parallel to table plane through MIC center: 

  2. In that plane distance from model center to diamond out-line calculated for all azimuth.

    MIC is drawn in red color
    indicates MIC center
     indicated Girdle center mass (model center)
    Diamond out-line is drown in blue color
  3. Minimum radius from step 2 is selected.
  4. Graphics is drawn as deviation from minimum radius.

3. Black curve line calculations

  1. Model is projected on MIC plane:
  2. Distance from model center to projection out-line calculated for all azimuth.

    MIC is drawn in red color
    indicates MIC center
     indicated Girdle center mass (model center)
    Projection out-line is drown in black color
  3. Graphics is drawn as deviation from minimum radius from chapter 2 step 3

4. Notes

  • If you have any question, please ask it in comments or send e-mail to developer.
  • If you find mistake, please describe it in comments or send e-mail to developer.
  • If you use report.dll 2.6.5.1 or later MIC will be used as model center.
