Functions Implemented:

• cudaRaytraceCore() handles kernel launches and memory management;
• raycastFromCameraKernel() is a function handling camera raycasting;
• raytraceRay() is the core raytracing CUDA kernel;

• boxIntersectionTest(), which takes in a box and a ray and performs an intersection test;
• getRandomPointOnSphere(), which takes in a sphere and returns a random point on the surface of the sphere with an even probability distribution;

• getRandomDirectionInSphere(), which generates a random direction in a sphere with a uniform probability;

Features 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

• Reflection
• Interactive camera
