About the Image No additional
primitives have been added since assignment 2 and I didn't add any
more to build this image--all I have are spheres and triangles
(and actually this image doesn't even use spheres). The
marble is Perlin procedural texture. Texture mapping
procedural texture is so much easier than bitmaps--and it looks
good. This room would've been a lot harder, if the walls
would've been wallpaper and the floor hardwood. All the
marble is slightly reflective and has a 0.05 normal perturbation
for fuzzy reflection. The glass box is made from
5 panes of green tinted glass. I made a slight modification
to my renderer for this image so the glass won't cast shadows.
You'll note that the marble wall behind the glass is not
shadowed--but neither is the image of the Mona Lisa...which was
the biggest problem. I only have one
light source. I never added more, so I had to deal with that
limitation here. In fact, I've named my ray tracer "ulmo",
which is an acronym for "one light, many objects" in Italian.
I've updated my image since this project was due. I ran more
samples per pixel, fixed a ceiling problem, changed the color of
the floor and attempted to fix my glass box. The box still
has issues because I need more ray bounces (this used 10 bounces)
in order to get the corners to be green instead of black.
This took 46 hours to render...so I'm just going to give up at
this point.
