Changelog

[1.2.0] - 2026-09-02

  • Added orthographic camera projection (camera_projection), independent from the existing perspective mode.
  • Orthographic frame auto-fits and centres on the real vegetation bounding box (instead of assuming it is centred on the world origin), with configurable camera_size, camera_margin, and a camera_fill (contain vs. cover) mode.
  • Fixed the sun to a physically constant Earth-Sun distance, independent from camera_distance (previously coupled, causing incorrect illumination parallax on close-range renders).
  • Added the orthographic example, reusing the default scene.
  • run_silvo.sh scripts now work from any invocation directory and consistently convert output_image.ppm to .png, including the gap-fraction example.
  • gap-fraction example no longer duplicates scene.txt (reuses default's).
  • Renamed example folders, dropping the ourique_ prefix (e.g. ourique_default → default).
  • Makefile: added clean-examples target, clean now also removes bin/silvo, and declared .PHONY targets.

[1.1.0] - 2026-08-24

  • Added vertical spheroidal crowns via x y z horizontalRadius verticalRadius.
  • Kept legacy x y z radius entries fully compatible.
  • Added scene parsing and geometry regression checks.
  • Added make clean for generated output cleanup.
  • More examples added.

[1.0.0] - 2026-03-04

  • Initial release.
  • Spherical crown illumination model.
  • Gap fraction, light partitioning, and canopy density metrics.
  • PPM image and ENVI multilayer outputs.
  • Settings file and CLI configuration.
  • Example workflows.
