Release updates
A new way to build 2D imagery
Images made from materials,
not just colors.
Spectra2D is material-based 2D imaging software from Aki Star Mitsukaru. Create material-aware images and explore their response to changes in illumination.
The idea, visible
Traditional pixels describe appearance. Spectra2D adds material-response information, giving illumination something meaningful to act upon.
Moving lights and spectral changes rendered in Spectra2D Editor. Play each video to explore the lighting sequence.
Beyond RGB
Spectra2D is not another lighting filter. It is a material-based 2D imaging system built around the relationship between matter, energy and visible response.
