Towards implementing ray tracing on FPGA at 2014.
While Imagination released a GPU IP with dedicated raytracing logic, still it would be meaningful to implement our own ray tracing on FPGA.
Here’s notes on ray tracing on FPGA nowdays(2014).
ARM + FPGA logic.
Zynq-based FPGA dev board can be purchased from $200 for example ZYBO http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,719,1197&Prod=ZYBO

– Robust Ray-Bounding Volume Hierarchy Traversal with
Reduced Precision Integer Arithmetic
Integer is saving its area by 6x than floating point .
