Here's some cool stuff I rendered with my raytracer!! By taking advantage
of multi threading I was able to render these images in about 20-30 minutes
where I used around 150-300 minutes of cpu time.
This image was rendered using global illumination but since it is a rather
dark scene there is not much light to go around, however it does add the
nice effect of making the pyramid fade to black towards the top. It also
adds some interesting shafts of light inside the sphere towards the top,
they are kind of hard to see but interesting nonetheless.
This image has some interesting reflections and refractions but it also has
sharp edges especially on the triangles. Luckily those edges can be
smoothed out via anti aliasing

Virtual reality scene
Ray traced images may look nice but you can't easily interact with them
unless you move very slowly. So here's a demo of a vr scene I made using
the google cardboard api.
In the scene the user can walk around and interact with not only geometry
but also sound!! (sorry about the low quality of the audio)
I set up a scene with 8 different speakers each playing a different aspect
of a song. Once activated via the record player the user can mute speakers to play around with
which parts of the song are active. The user can also move around the
scene to hear the audio from different angles, The audio is also occluded
you'll notice in the video that when the user steps through the pathway in
the beginning the audio is much louder drawing them to the record player.
To contrast the high quality raytraced renders here's a low quality
screencast of the scene, the audio should come from both channels but the
screencast was not able to pick up on that so the video only has one audio
channel so you may only hear sound from one ear in your headphones and/or
it may be quiet on a speaker.
I got all the models for this scene from the unity store and
compiled the scene and wrote the little scripting necessary myself.
Overall it was pretty easy and fun to make. And fun to play the audial
experience is very interesting.
