Note the dir vectors must be normalized. If trace_high_res is true, High res mesh info are traced using rays with given org and dir, typically on the Low res mesh, and, if opts.myPixelSamples also is 1, the input org and dir are so modified by the results with dir being the surface normal. tanu and tanv are tangent vectors on Low res mesh that correspond to each pixel. They are used to jitter the org. Both vectors can be passed null if opts.myPixelSamples is 1.
