Sun Ray Count Angular Spacing Calculator
Distinct evenly spaced ideal sun-ray center directions, not duplicated360endpoint or required ray count for a named flag.
Description
Evenly spaced sun rays divide a full turn into distinct center directions.
Evenly spaced sun rays divide a full turn into distinct center directions.1
A chosen start angle sets their rotation without adding a duplicate direction at the end of the circle.
When to use Sun Ray Count Angular Spacing Calculator
Use this tool when you need to reproduce the stated calculation from measured records or independently selected model inputs. Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
How to use Sun Ray Count Angular Spacing Calculator and understand its results
- Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
- Enter rayCount, startAngleDegrees, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| rayCount | Ray count | number | Required |
| startAngleDegrees | Start angle degrees | number | Required |
Use an integer ray count from one to sixty-four and a finite start angle in degrees. Return spacing 360/count and count unwrapped angles. The start angle is not normalized to a full-turn interval.
angle_i=start+360i/count, i=0…count−1 Symbols follow the input and output meanings and the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or reference | object |
| result.raySpacingDegrees | Ray Spacing Degrees | number |
| result.rayAnglesDegrees | Ray Angles Degrees | list |

}Limitations and assumptions
The calculation uses supplied geometry, observations, or annotations. It does not establish an official construction specification, national identity, or universal design quality.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related review, use Circle of Stars Ring Radius Calculator: A circle of star centers must leave room for each star’s radial extent and an edge margin. The available diameter therefore bounds the radius of the center ring. For a complementary step, use Rising Sun Disc Offset Calculator: A rising-sun disc can lie partly above a horizontal horizon. Its center and radius determine an ideal circular segment area in a top-left coordinate frame with y increasing downward.
