Inspect the structure, then follow its assembly order.
The science
Textbook reference: θ = 1.22 λ / D rad; A = π D² / 4 m²; f = N D m; r = 1.22 λ N m. Arcseconds = radians × 180/π × 3600.
The independent check measures the animated ray geometry against r, using numerical line intersection. The rays illustrate an ideal converging cone and do not calculate diffraction. The Airy radius is a circular-aperture reference, not the exact segmented pupil response.
Genuine features: segmented primary, secondary mirror, three-point supports and a focal instrument. Engineering-inspired: frame, service platform and instrument housing. Simplified: planar tiles, enlarged actuator travel, schematic rays, fixed geometry scale and no atmosphere, wavefront control solver or structural analysis. No speculative physics is used. All dimensions and control values are illustrative or scaled; equation constants are textbook.
