BeamTest is a test bed for examining the behavior of light in POV-Ray. In
version 1.2 there is a new demo file, plus several minor updates:
- A demo scene is added that uses Ive's SpectralRender package.
SpectralRender and its prerequisite are not in the Object Collection,
but download links are provided in the documentation.
- A parameter is introduced to color the environmental lighting. This
was done to accommodate SpectralRender, as a flat emission spectrum
does not appear white to humans.
- The orthographic camera is introduced, and made the default.
- A parameter is introduced to control the image height. BeamTest
normally does this automatically, but it ASSumes that the pixels are
square. The POV-Ray docs warn that this is not always the case,
although I personally have not seen such machines since the 1980s.
Still, it was trivial to add.
