Maraytr is a ray-tracer written with high focus on algorithms and data structures rather than on performance. I decided to make it to get deeper understanding of theory and math behind ray-tracing. Also, ray-tracing is fun! The core was written in four days in C# without any third-party libraries. The scene is represented as Constructive Solid Geometry (CSG) and supported primitives are sphere, cube, and plane. It is possible to do basic boolean operations like union, intersection, subtraction, or xor.

Video of simulation of growth of simple trees restricted by environment created using L-systems. This animation was made to demonstrate power of my L-system framework Malsys and to have fun with L-systems. Whole simulation is one L-system with sub-L-systems for leaves and blooms.

Malsys is an L-system processing library with web interface and interactive gallery. Malsys supports advanced L-system features like context rewriting or parametric L-systems as well as some unique features like rewriting symbol as another L-system. This project was done as my bachelors thesis at Charles university in Prague

This project is relatively advanced L-system library written in Haskell. Out of the box it supports symbols with parameters, conditional rewriting, and it can evaluate expressions with binary and unary operators. There are two available L-system interpreters: text and SVG vector graphics. The code is well commented and written with extensibility in mind. It is easy to add new operators, new interpreters, or even extend the grammar. This project was my final program of Non-procedural programming class.

Wandering is a generic maze generator, solver, and game playable in a console. It supports hexagonal and rectangular mazes and two types of maze generators. Cool thing is that the maze type is independent of the solver. Every solver can solve every type of maze. It is possible to define new maze types, generators, and solvers. Another cool feature is the UI system in a console including menus, text boxes, windows, and screen manager. This was my first larger program written in C++.

Animation of growing tree made using L-systems. Animation starts as a small tree branching only to the right and then start turning left revealing beautiful structure. Basic rules of the tree are based on Pythagoras tree however resulting tree is not pure Pythagoras tree. This animation was made as homework to the computer graphics class.

Proof of concept of a bridge-builder game for Android made as part of Game Development course. The game written in Java supports building bridge struts and simulating physics with Box2D engine and uses AndEngine for rendering. A nice touch is parallax background.

Library and interface for automatic music sheet recognition. Input is image of sheet of music and output is standard MIDI file. Uses database of symbols together with dynamic recognition to do the recognition. This was my final project of High school and I won 'A little Czech head' prize for it.

Big poster (4 x 1.7 m) of 4 deep zooms into Mandelbrot set. I made this poster because I was amazed by Mandelbrot set and I had a program (Mandelbrot set explorer) to generate high quality images. My dad helped me to print this big guy and later I donated it to the institution where I was having programming courses after school as a kid. It is there till now.
