Open source software projects experience

  • Linderdaum Engine http://www.linderdaum.com (2004 – present) Real-time 3D rendering engine.
    • Designed and developed a 3D engine from scratch
    • Implemented many modern rendering techniques and effects
  • LinderScript Run-Time (2005 – 2007) An object-oriented scripting system and virtual machine integrated tightly into Linderdaum Engine. The goal was to create a system allowing script classes to be inherited directly from native C++ classes with absolutely no changes to a native C++ code and transparent invocation of scripted methods from the C++ code.
    • Implemented a scripting system where scripted classes can be inherited from C++ ones
    • Implemented a fast byte code virtual machine for it (comparable to Lua and Perl)
    • Got it done with only standard C++ features used (templates metaprogramming)
    • Made an ad hoc C++ code prepocessor to autogenerate all the necessary binding code

Research & development projects

Inspection of screw thread fits by virtual gauges method using data acquired from coordinate measuring machines and computer tomography systems

Funded by OPTEC – Carl Zeiss IMT GmbH grant, 12.2009-12.2010

Originator and co-researcher. The goal of the project is to find suitable simulation and feature extraction methods to implement a so called “virtual gauges” inspection method for screw threads. The project consists of two stages: the first stage is to extract screw threads’ parameters from point clouds scanned on 2D coordinate measuring machines; the second one should end up in feature extraction from 3D volume data obtained via computer tomography systems (Carl Zeiss Metrotom 1500) with possible approach to do a fit simulation of two CT-scanned threaded workpieces.
