Video :: Dive Into Recursive Geometry!

Here is my presentation from Assembly 2014, talking about Natural Geometry and the effects creating it can have on our level of awareness, and introducing our upcoming Virtual Reality Experience, Geometrify.


Big thanks to Olli Sinerma for arranging this VR -track and all the other speakers, Paavo S Ho, Kaomas Turmakallio and Samuli Jääskeläinen, really enjoyed all of your sets. Be sure to check out their presentations on the same Youtube channel if you are interested in Virtual Reality and where it has been coming from and what is happening right now.

About 15-20 people tried our Geometrify tech-demo, some of the comments included “pure joy”, “being in a flow state”, “damn nice” and many others. Thank you for everyone testing it out and giving feedback!

PS. We’re looking to hire a graphics programmer here in Helsinki to continue work on Geometrify. Please contact us if you are interested! :)

Running IBNIZ, realtime audiovisualizer on Mac Os X

Here is something very cool: http://pelulamu.net/ibniz/

It is a realtime, compact 8-bit style audiovisualizer that has it’s own virtual machine and language to input code into. It can produce very nice demoeffects using only a minimal set of commands, check out the example video:

How to get the source code up and running on Mac Os X (tested w/ 10.6) ?

* Download and install XCode if you already haven’t done this)

* Install MacPorts: http://www.macports.org/install.php

Then run

sudo port install libsdl-framework

Command from the terminal to install the SDL development framework.

Grab the sources for Ibniz, untar, cd, and run make to compile.

I noticed that I have to modify the getticks() function in ui_sdl.c in order to get usable framerates:

int getticks()
{
  if(!ui.opt_nonrealtime)
    return SDL_GetTicks()/3;
  else
  {
    return dumper.framecount*50/3;
  }
}

Dividing by three seems to do the trick, without it the frames start skipping too much for some reason.

I hope to integrate GeoKone scene loading into this, that would be very cool as all the GeoKone formations can be expressed in 1-2 lines of code and with a very simple core engine that reads the data.

I will be hacking on this thing for a while. Thanks Viznut for this great christmas toy :)
