CPE 473 Spring 2013 Final Project and Images

By Ray Go

Geometric Transforms and Reflection

This image shows the application of geometric transforms to create a heart.
This image also shows reflection and shadowing.

Basic Shading with Shadows and Camera Transforms

This image shows the application of camera transforms and shadowing with
different types of geometry.

Refraction

This image shows refraction of planes and a sphere.

Bounding Volume Hierarchy

This image demonstrates my implementation of a Bounding Volume Hierarchy.
There are 36905 spheres in this scene, and it takes about

Depth of Field

For my final project, I decided to implement depth of field. The images
below show different focal length, which will bring into focus one of the
three sphere in the scene.

Focal length: 7.0

Focal length: 9.5

Focal length: 12.0

Global Illumination

I implemented Monte-Carlo path tracing to get global illumination. My current
project only handles diffused objects, but I plan to implement refractions in
future work.
