Скачать или смотреть 269life (extended version)

Updated recording of my 2017 WEBGL demo page "269life"
https://www.wothke.ch/269life/ (replaces my earlier recordings). In demoscene spirit this page is the result of some "just for fun" programming used to explore the features of WEBGL.

In addition to showing some cool raymarching based realtime graphics, the demo is dedicated to "269 Life" and the matching title is meant to attract some extra attention to that meaningful movement (see http://www.269life.com).

I did this updated recording using a GTX 1050 in 1024x768 "fullscreen" mode. However the limitations of my recording equipment as well as the use of lossy video compression mean that for higher quality graphics you should better look at the original page directly: My older GTX 460 card got me about between 20-60fps for this page so it should not be a problem for more recent hardware.

Update june 2020: Originally, i.e. 3 years ago, only Chrome was capabale to render this page correctly whereas flaws in its WEBGL GL_EXT_draw_buffers implementation made Firefox a total fail at the time. By early 2019 Firefox had fixed those issues and both Chrome and Firefox could be used to correctly watch the page. Unfortunately Chrome as well as Firefox then adopted an incompatible dumbfuckery in the second half of 2019 so that neiher browser any longer can be used to correctly watch the page. I am sick and tired of mopping up after those idiots and I will no longer update my page. I suggest you get yourself a respective portable version of one of the older 2019 browser versions that still work correctly (Chromium 75, Firefox 66.0).

The renderings used in this demo are based on the 'pseudo kleinian' algorithm by Knighty (see Fragmentarium examples). The used 'distance function' variations were derived by experimentation and inspired by different work in the http://www.fractalforums.com (e.g. by Crist-JRoger, et al.).

I've migrated parts of "boxplorer2" for use with THREE.js/WEBGL such that "boxplorer2" could be used to edit the camera path. It also provides the base for the z-buffer calculation. Thanks to Marius for some helpful suggestions.

This page would not have been possible without the many clever algorithms for things like: Blinn Phong reflection, ambient occlusion (Alex Evans), bokeh (David Hoskins), random noise (Inigo Quilez), etc (see page's source code for more detailed references).
