Projects

Stubble - Virtual hairstyling plug-in for Autodesk Maya

A software project by: Martin Bulant, Ivan Jankovič, Jan Kadlec, Petr Kadleček, Martin Kahoun, Martin Liška, Martin Šik, Aleš Tamchyna. See Stubble on GitHub.

Stubble is a plugin for Autodesk Maya 2011 providing user-friendly virtual hairstyling, i.e., creation, editing, and animation of hair or fur on 3D models. It is written in C++ and MEL scripting language using the OpenGL and Qt libraries.

The main features include: low disk space footprint of the generated data at render time; procedural hair generation and interpolation via editable guide hairs; hair dynamics via Maya NURBS curves; wide user control over the output using textures; intuitive interface with real-life like tools, e.g., scissors or brush; large variety of input devices, e.g., mouse, tablet, or a haptic device.

PigeonBot - an Unreal Tournament 2004 bot

A semestral project for Human-like artificial agents course written by: Petr Kadleček, Martin Kahoun.

PigeonBot is a bot for Unreal Tournament 2004 capable of playing Capture the Flag in teams. It is written in Java using the Pogamut 2.4 platform. It was tested on the CTF-FaceClassic map.

Its main features are: simple, yet good if-then behavioral system; leader oriented reasoning using the in-game chat communication; sniping behaviour; capability of supporting flag carriers.
