CG2 Code For Art conference 2016

CG2 Code For Art is an idea which started as an opportunity for meetings and communication among the professionals in the sphere of visual arts. Six years after its inception CG2 Code For Art has become the main annual event for 3D artists, animators, architects, developers, students and educators in the computer graphics.

This year, the conference is taking place on two consecutive weekends – different sessions for Architecture, VFX/Gaming industry and CG Developers.

The chance to invite as speakers the creative minds behind some of the most prominent international projects, encourages us to see CG2 Code For Art as a platform for an union of artists and a great source of inspiration and knowledge for young people.

29 October 2016

09:00 - 09:30 Registration
09:30 - 09:40 Opening
09:40 - 10:30 Rendering microfacet surfaces on CPU and GPU - Asen Atanasov, Chaos Goup
Asen will present this year's paper by Chaos Group "A Practical Stochastic Algorithm for Rendering Mirror-Like Flakes" which was presented at SIGGRAPH 2016 and published by ACM - http://dl.acm.org/citation.cfm?id=2927391. He will explain the original CPU algorithm and how it is adapted for GPU implementation.
The presentation will be held in Bulgarian
10:30 - 10:40 Coffee Break
10:40 - 11:30 Deadlocks, Leaks and Race conditions - Mihail Mihaylov
Some of the hardest bugs to diagnose and prevent are deadlocks, leaks of memory and other resources, and race conditions. In this presentation Mihail is going to discuss common types of these bugs and to describe how to diagnose and prevent them. He also will share case studies from his experience.
The presentation will be held in Bulgarian
11:30 - 11:40 Coffee Break
11:40 - 12:30 Test Driven Development: Creation of quality code - Yordan Madzhunkov
Yordan will share his experience with Test Driven Development (TDD) - methodology for developing code where tests are written before the code itself. TDD is not a substitute for traditional testing, it’s a methodology that allows to develop effective and comprehensive Unit tests. Applied properly TDD leads to extremely high quality source, high performance, easy maintenance and with very few defects (bugs).
If you are a programmer who wants to adopt TDD, then this lecture will be definitely useful for you.
The presentation will be held in Bulgarian
12:30 - 13:40 Lunch Break
13:40 - 14:30 On the Buoyancy of the Floating Point - Martin Krustev, Chaos Group 
This talk will focus on the behavior of floating-point numbers, as described in the IEEE754 standard and supported in hardware in most contemporary CPUs and GPUs. Accent will be on error metrics in floating-point calculations and how to make full use of the information encoded in the floating-point data types.
The presentation will be held in Bulgarian
14:30 - 14:40 Coffee Break
14:40 - 15:30 Doctest: Inside the internals of a modern C++ testing framework  - Viktor Kirilov
The framework is inspired by the "unittest {}" functionality of the D programming language and Python's docstrings - the project's mantra is: tests can be considered a form of documentation and should be able to reside near the code they test. The lecture will have a brief introduction about what the library can do and how it is different from all the rest. Then the most important and interesting features will be dissected and explained - like for example the automatic test registration or the expression decomposition with templates.
The presentation will be held in Bulgarian
15:30 - 15:40 Coffee Break
15:40 - 16:30 Recognizing and comparing of 2D features - Orlin Dimitrov
The lecture is going to present a method of image processing that recognize 2D models. It will show  its strengths and weaknesses. The content will be focused on the math in the method. The model is tested in  of Windows and .NET. environment.
The presentation will be held in Bulgarian
16:30 - 16:40 Coffee Break
16:40 - 17:30 How can I boost my productivity? - Yordan Miladinov, Chaos Group
Traditionally a programmer's productivity is considered in organizational terms only, neglecting any personal factors. It's clear that productivity does not solely depend on the outside environment. It's time to discuss what are the interpersonal qualities that can boost one's productivity in the workplace and see how can we use them to our advantage.
The presentation will be held in Bulgarian
   

30 October 2016

09:30 - 10:00 Registration and Opening
10:00 - 10:50 Real-time cartoon style rendering of a 3D scene with GLSL - Hristo Lesev, DiaDraw
Everyone seems to be doing photorealistic computer graphics nowadays and there are many well known algorithms, which can approximate with a great level of accuracy how light behaves in the real world.
In this talk we will go over another branch of the computer graphics field: non-photorealistic rendering (NPR) of a 3D scene.
Our goal is to see how something so subjective as an artist’s style and process can be represented by a mathematical model and rendered on a computer screen. In the process we will explore different artistic styles such as drawing, technical illustration, and animated cartoons.
The talk will shed light on the workings of the human visual system and cognition and will demonstrate how they affect the NPR shading model. Different shading styles will be demonstrated as interactive WebGL examples.
In the end we will be able to render our 3D scene to look just like a sketch from Leonardo or a Norman Rockwell's painting.
The presentation will be held in Bulgarian
10:50 - 11:00 Coffee Break
11:00 - 11:50 GPU 101 - Vladislav Vulchev, Chaos Group 
Video cards are becoming more and more powerful. The excellent handling of multithreaded tasks gives them great application in various fields. Computer Graphics is one of them. We'll dive into a  video card, see what's inside of it and how it works.
The presentation will be held in Bulgarian
11:50 - 12:00 Coffee Break
12:00 - 12:50

12:50 - 13:40 Lunch Break
13:40 - 14:30 Using MDL to Share Physically Based Materials -  Lutz Kettner and Jan Jordan, NVIDIA
The basics of NVIDIA's Material Definition Language (MDL) will be discussed, showing how a single material can be used to define matching appearances between different renderers and rendering techniques. Users will learn how physically-based definitions can be defined while developers will learn what’s entailed in supporting MDL within their own product/renderer.
The presentation will be held in English
14:30 - 14:40 Coffee Break
14:40 - 15:30 Getting your hands dirty with GPUs - Alexander Soklev, Chaos Group

15:30 - 15:40 Coffee Break
15:40 - 16:30 Case study: Developing V-Ray Bench with Haskell - Daniel Taskoff, Chaos Group

Daniel will give answers to these questions in 40 minutes, showing real examples from the project and talking about the different problems that arised during the work on it.
