An FFGL source and an effect that build space pictures the way NASA's are made: gas lit by the stars inside it, seen through Hubble's and Webb's real filters, each filter's grey image given the colour its release gave it. Fifteen famous targets from the Pillars of Creation to Webb's First Deep Field, seven generative skies, and meteors, a supernova and its light echo on a button. No photograph is shipped or sampled; the light is worked out.
This demo runs the plugin's shaders and a port of its CPU half in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
