Abstract
Ray tracing is a method of rendering high-quality images and video by calculating what happens to virtual light rays in a 3-dimensional scene. It is capable of creating for more realism than traditional Z-buffering methods. This paper describes the design of a hardware ray tracing system implemented on a multi-FPGA Xilinx Virtex-E prototyping system. The result is a hardware ray tracer that is capable of out-performing a 2.4GHz Pentium 4, running a well-known high performance software ray tracing algorithm, by up to a factor of thirty. When these results are projected forward into a next generation FPGA system, consisting of a single large Virtex 2 Pro FPGA, it is found that the system should be able to out perform the same Pentium 4 by up to two orders of magnitude, and the fastest known hardware implementation, the AR350, by up to a factor of three.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
