]]> I recently updated <Bloccupy>

it’s an interactive media installation with kinect/video input, which I built for Projektil, Zurich in 2015.

It wouldn’t run anymore for various minor reasons. plain old code-rot and no devs around to prevent it.

while getting rid of some dust and freshing it all up, I did a nice screencast I wanted to share 🙂

 

I also wanted to summarize the basic building blocks and concept used for Bloccupy.

As most graphics-related things I did in the past years, it relies on crossplattform C++ and OpenGL.

 

pin toy metaphor

 

The underlying metaphor for the concept is a pin-toy.

Like in other projects I really fancy the procedure of downsampling something close to the point where it becomes unrecognizable and exploring this borderland.

To achieve the blocky look and elevation behaviour I manipulated a simple array of points in 3D space.

Those are fed into a GLSL geometry-shader and transformed into cuboids.

As input we used a raw depth-camera image in combination with video-footage, the update of point positions is performed with a couple of OpenCL kernels.

The depth values and/or color information from video is mapped onto the elevation of the cuboids and their color.

The scene is shaded and lit with a couple of point-light sources, to be able to visualize the intricate details of the resulting geometry.

 

colormap

optionally a colomap can be applied to better highlight different elevations.

I used this one, called “hot iron”:

 

results

nothing more to add, enjoy this outtake from Carl Sagan’s Cosmos, rendered by the Bloccupy Engine.

 

hope you like it,

in 2015, while working at projektil.ch in Zurich,

I developed a piece of software for live-perfomances and visuals with the working title <Psycho Manege>.

the concept-idea was to control a multi-stage round-robin filled with animated and audio-reactive 3D models via gamepads and midi-controllers.

the output of the program would be projected on a 360 degree stage, mapped with 4 projectors on several layers of semi-transparent cloth.

following are some screen-captures of earlier proof-of-concept sequences.

focus of these tests was to showcase the audio-reactive vertex-distortion, implemented by generating a simplex-noise texture on the gpu and feeding that into the vertex shader-stage to move vertices along their normal vector, a.k.a. displacement mapping. not particulary tricky but it sounds and looks cool 🙂

and featuring myself:

this work led to a two evening, bombastic live-visual performance together with my colleague Moritz Flachsmann at Lethargy Festival 2015, Zurich.

basically I was performing the animal round-robin, adding/removing/controlling the 3D models and parameters, while we fed the output into Modul8, where Moritz took over the 2D domain.

we were quite happy with our work-flow and results. here’s Projektil’s documentary video of the event, cut by Cadu.

thank you Moritz and Projektil for this one!
