Extending IL (proprietary functional scripting language)

This is the current incarnation of the language that previously was named Intercol. More information here: http://www.kees.cc/il/

Latest achievements:

• Integration with Oculus, both graphics and sound.
• Implementing an original sound synthesis engine, with both recording and real time performance capabilities. Emphasis on complex analytical signal processing.
• Making the language multi-threaded, also separating main interpreter, and OpenGL working thread.
• Implementing complex mesh manipulating library, including ‘organically’ growing capacity through strictly local vertex operations.
• Extending type system with (geometric algebraic) multi-vectors, dual numbers and dual quaternions.
• Integration with OpenGL 4.x and OpenSceneGraph.
• Automatic differentiation of multidimensional functional maps.

Sr. Software Engineer I

Spore prototyping

• Started in prototyping team of 3 engineers (+ Will Wright, who is chief designer of Spore, and before that of 'The Sims' and 'SimCity')
• creature editor for articulated bodies
• Genetic algorithm for development of nervous systems for these, optimizing locomotion efficiency. Used technologies: OpenGL, ODE and my own language IL ( http://www.kees.cc/il/ )
• Artificial evolution of body plans based on L-Systems with linear genetic code and network based development stages

Spore production

• Procedural animation systems based on high-level scripting language
• Walking algorithm for creatures with any number of legs, in random configuration.
• Some of this work is reflected in the Siggraph 2008 paper: "Real-time motion retargeting to highly varied user-created morphologies"
• Unified two level animation/behavior system:
  • body parts in creatures
  • creatures in group
• Used technologies: LUA and Havok.
• This was basically the creature animation as demonstrated by Will at GDC in 2005.

• Texture atlas generation for dynamic content by implementing LSCM (least squares conformal mapping).

San Francisco, CA

Technology Founder, Principal System Architect

• Responsible for basic research and technical design and implementation.
• Designed a very large system for 3-D modeling, animation and rendering (3DGO).
• Designed and implemented the language 'Intercol' as basis for this system.
• Designed and implemented the original system (modeling, surface texturing, transformation, lights, camera, etc.) in this language.
• Also integrated a very advanced procedural texture mapping and shading language into Intercol.
• Designed TIFF extensions for post processing and compositing of synthetic images. (pixel info on depth, surface normal, lighting, texture coordinates, etc.)
• Designed and implemented a (2nd) new programming language IL with the following characteristics:
• unification of image processing, (2-D and 3-D) modeling, texturing, animation and sound, based on intensional logic.
• generic user-interface coupling,
• object oriented linking of C-functionality to interpreter
• Designed and implemented a new texture editor for 3DGO.
• Conceptual design of an authoring system for 'virtual sets' for the San Francisco office. In 1996 appointed head of research there.
