Refraction was fixed. Doesnt have the dark ring anymore. Turns out I forgot to normalize a vector somewhere.

Aight Last one for now. Has 10 bounces, Reflections, Refractions, Absorption, and an incorrect Fresnel Reflection. Ill figure this out after I finish the triangle intersections. WILL REVISIT.Processor: i7-10750H

what if EVERYTHING REFLECTED????GONNA DO REFRACTIONS NOW

AAAAHA I FIXED IT. SO MY z-BUFFER CALCULATIONS WERE OFF. I NOTICED THIS ACTUALLY WHEN WE WERE DOING SHADOWS AND I HAD TO CREATE A SEPARATE NODE TRAVERSAL AND INTERSECTION. I TRACED THE PROBLEM BACK TO THE REFLECTIONS, MAKE THE APPROPRIATE CHANGES, AND NOW IT DEFINITIVELY SELECTS THE CLOSER Z-VALUE. LETS GOOOOOOOOOOOO

Obviously somethings wrong, but I got a bounce going.Also the node traversal has been fully fixed now. It can properly traverse and transform the rays to and from object space.
