My
design choices were simple. I’m still choosing to have a one-file program to make
it easier for me to understand and to make it easier to transport between
different systems. I followed the structure/architecture suggested in the
notes. I choose two places to optimize the code. First, I used the box
intersection code to check the bounding box for the height field (hf) and
second, within the hf intersection I checked if the discriminate was zero
before marching on. For numerical precision, I chose to only consider
intersections were t > than .00001, it seemed to give the best results for
the hf. My creative image is an abstract image that includes Winter Olympic
symbols. This project took me over 50 hours, which was long, but again, I am
learning more than just the ray tracing concepts. I am learning to code in c++
using all of the benefits of the language. So far the three projects have
helped me to learn more than most classes in general. I am presently working on
a geo hf for extra credit, if I get it finished before midnight it will be
here:
