BLooP vs. JavaScript vs. Kray vs. Scheme Comparison Chart

Welcome to the Dictionary of Programming Languages, a compendium of computer coding methods assembled to provide information and aid your appreciation for computer science history. BLooP was a very simple recursive block structured language invented by Douglas Hofstadter for his book Godel, Escher, Bach. It features simple subroutine structure, very simple number and boolean handling, and recursion. The interesting aspect of BLooP was that it offered only bounded loop constructs, and was therefore incapable of expressing certain general recursive computations.

Kray is a state of the art global illumination renderer that allows very fast and accurate rendering of scenes where indirect light plays important role. It includes the most advanced modern algorithms and optimizations to allow it to render full global illumination, reflections, refractions and caustics quickly on standard computers. Fast global illumination: light/photon mapping – biased, but very fast and not much dependent on number of ray recursions, path tracing – unbiased with serval sampling optimizations, irradiance caching – for fast, view independent, reusable GI solution storage, caustics. Light models: point/directional, line lights, area lights, background light, HDR image based lighting, lights pre sampling. Instancing: allows repeated re-use of the same geometry in multiply locations in the rendered scene with very low memory consumption, instanced geometry can be also instances, even self cloning is possible with user defined number of recursions.
