In 2015 I was asked by Online Star Register to make a data visualization of their star data similar to 100,000 Stars. It's rare one gets a chance to iterate on previous work so I was excited at the chance to make some big improvements in terms of visual fidelity, quantity of data, and sound design.
Ideation + Dev
I was given ample time to create concept art to inspire the client on what the final site would look like. Taking inspiration from "Powers of Ten", the tour would go from the view of star gazing, to visiting the stars, and beyond. At each phase relevant information would be shown, be it about the star in question, the constellation, cultural and scientific information about each of those.
I also had to consider each text element for localization. This was done by creating a text lookup manifest with an associated ID for each text block. This was then replaced on the client side.
The rendering for the star was a three step process: the surface shader, the corona mesh geometry that had a vertex shader to animate in and out, and the post-processing shader that causes light to bleed outwards from the center of the screen.
Like 100,000 Stars, the point of transition between real data and "fake" galactic data had to be determined.
