Enhanced image quality for holobuilder

During the last few weeks we got a lot of helpful feedback regarding our holobuilder platform, thanks to everybody who commented on our work. Especially the image quality was heavily criticized, hence we worked hard on enhancing it accordingly. Here a little demonstration of the different image qualities before and after our latest update with the great images of Sacha Griffin.

For everybody interested in how we achieved this improvement here a few technical details:

  • Old version:

    •  Only one texture with max 4096×4096 pixel
    •  Compression of the texture with 60% preservation of quality
    •  Sphere max 2MB
      -> All slides can be loaded quickly
  • New version:
    • Multiple textures with 2048×2048 pixel
      -> Original image is not saved as one square and therefore later on stretched (all photospheres have a 2:1 width-to-height ratio, e.g.: 16000x8000px, picture is first sliced into 2 squares, then both squares recursively into 4 squares (at the moment limited to max 8 slices).
    •  Compression of the individual textures with 80% preservation of quality
    • Sphere max 6 MB
    • Spheres have a highly compressed preview texture in addition to their normal textures.
      -> Fast loading of slides because first not everything is loaded at the same time, as only the preview texture is loaded at the start.


We hope you all enjoy the new image quality. In the future we plan on having a super high quality mode with 100% preservation of quality. Thanks again to all who provided us with feedback, we hope you will keep using and constructively critiquing holobuilder, so that we can keep on improving.

“Each year over 800 startups apply to the EVC via a dozen of regional or technology-focused qualifiers to present their company, engage with top industry experts and network with potential investors. The contest element comes from the selection of the best quartile (Top 25%) at each of the qualifiers who continue to an end-of-year major event with more than 100 entrepreneurs and also 100+ venture investors. 120 finalists of this event will be reviewed by a top Selection Committee and the 25 best startups (9 ICT, 8 life sciences and 8 cleantech) are awarded.”

Excited and proud of the support from the “German Accelerator” there is no rest for the bitstars-team. The next big challenge “IdeaLab” is to be faced on 10th and 11th October 2014 in Vallendar, Germany. “IdeaLab” is Europe’s biggest student-led start-up conference. As if that were not enough, bitstars was selected as one of nine start-ups out of 100 applications from various countries to pitch at the event. Mostafa Akbari, CEO and joint founder of bitstars, presented the unique entrepreneurial vision and got directly to the heart of the business concept. The positive response of the audience allows the bitstars-team to be optimistic about the results, especially because some investors showed increased interest in the series A planned 2015.
