Tumblr for R&D of lucille renderer.

This is my tumblelog for my lucille renderer.
Scraps, notes, quotes and etc. found on the web which is valuable for renderer development(and some quantitative finance).

“Parabix (Parallel bit streams for XML - TM) demonstrates a fundamentally new way to perform high-speed parsing of XML documents. Byte-oriented character stream data is first transformed into eight parallel bit streams, each bit stream comprising one bit per character code unit. Code units may be ASCII characters or UTF-8 bytes, for example, with one parallel bit stream defined for each of bit 0 through bit 7 of each code unit. Given such a representation, the 128-bit SIMD (single-instruction multiple-data) registers of the SSE (Intel architecture SIMD technology) or Altivec (Power PC architecture) may be used to process 128 code unit positions at a time.” Parabix - Trac
