Mind grid

Once CorpGlory Dev team worked with Dima Barbanel and his team - masterskaya.pro. The idea of the project was to make computational art based on the data about graduates of a Russian business school. The resulting graphics should be projected during photos creation for the person that is being interviewed. And it turned out to be an awesome result.

Team ¶

Victor Gorbachev and Andrei Kondakov pushed the complexity and the concept even further, proposing special requirements from the shooting point of view: the app should produce a series of frames “growing” inside out. In addition, I was asked to make a tool where teammates could work on together.

Technologies ¶

We were interested in a series of images that we will project later. In addition, intermediate results need to maintain teamwork. I used something called paper.js — a great tool to work with vectors and HTML canvas. I made pictures serializable to a binary format to store on node.js server, so team members could work together on graphics..

Algorithm ¶

We applied the same algorithm for every image, but with different values of variables. I have different types of figures. Each figure is a sequence of curves. Every curve is an array of smoothly connected dots in polar coordinates. So I can just take any r(θ) — a function of angle, take 10 or 20 points of this function, and then smoothly connect. I need to get these dots separately to make distortion. Distortion is the sum of “bubbles”. Each bubble is a normal distribution. In the case of a circle, the algorithm begins with r(θ) = 1, and then adds a Gaussian, screwed to polar coordinates.
