Introduction

I am working on a Ray Tracer using CUDA as part of my GPU course at UPenn. This page will be used to show my progress. The goal is to render scenes using a simple ray tracer on the GPU.

I am primarily using the GeForce GT 650M card with 384 Cuda cores. Specifications can be found here.

In this project, base code has been given for:

• Loading, reading, and storing the TAKUA (a renderer created by the TA for the course) scene description format
• Example functions that can run on both the CPU and GPU for generating random numbers, spherical intersection testing, and surface point sampling on cubes
• A class for handling image operations and saving images
• Working code for CUDA-GL interop

The following features have to be implemented:

• Raycasting from a camera into a scene through a pixel grid
• Phong lighting for one point light source
• Diffuse lambertian surfaces
• Raytraced shadows
• Cube intersection testing
• Sphere surface point sampling

At least 2 of the following features also need to be implemented:

• Specular reflection
• Soft shadows and area lights
• Texture mapping
• Bump mapping
• Depth of field
• Supersampled antialiasing
• Refraction, i.e. glass
• OBJ Mesh loading and rendering
• Interactive camera
