Smallpt c++
WebSmallpt is a C++ global illumination renderer written in less than 100 lines of code. Global illumination is done via unbiased Monte Carlo path tracing and there is multi-threading support via the OpenMP library. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark smallpt.
