Overview

Closed three-sided element built from two non-collinear adjacent segments.

Class Method Summary

• .[](segment_a, segment_b, position: Origin) ⇒ Sevgi::Geometry::Triangle

  Builds a triangle from two adjacent segments.

Class Method Details

.[](segment_a, segment_b, position: Origin) ⇒ Sevgi::Geometry::Triangle

Builds a triangle from two adjacent segments.

The closing segment is the direct vector from the end of segment_b back to position. Segment order controls orientation; reversing the inputs returns the corresponding opposite orientation. Zero-length or collinear inputs are rejected using the current numeric precision.

Parameters:

• segment_a (Sevgi::Geometry::Segment, Array<Numeric>) —

  first segment

• segment_b (Sevgi::Geometry::Segment, Array<Numeric>) —

  second segment

• position (Sevgi::Geometry::Point, Array<Numeric>) (defaults to: Origin) —

  starting point

Returns:

• (Sevgi::Geometry::Triangle)

Raises:

• (Sevgi::Geometry::Error) —

  when segments or position cannot be coerced, or the segments are degenerate
