In this project, I followed the instruction and gradually implemented the required function in ray tracing. The main programming language is C++, and OPENGL and GLUT are utilized to simulate the scene and object.

Shading

Generate shading effect according to the positions of lights and type of material of object.

Input	Output

Shadows

Add ray traced shadows to ray tracer system.

Input	Output

Reflection

Add reflection and refraction effect.

Input	Output

Triangular Meshes

Add plane and triangular mesh object types to the ray trace system.

Input	Output
	Rendering time:0:04:29

Space Partitioning

Add bounding volume hierarchy (BVH) support to accelerate rendering.

Input	Output
	Rendering time:0:00:04

Textures

Add textures to objects as well as background and reflection/refraction environment images

Input	Output

Antialiasing

Implement adaptive antialiasing with multiple samples per pixel. Comparing to the above output, the backgroud is not crazy now and looks smoother.

Input	Output

Depth of Field

add depth of field support

Input	Output

Soft Shadows and Glossy Surfaces

Implement soft shadows for area lights and glossy reflections and refractions.

Input	Output

Monte Carlo GI

Using Monte Carlo sampling for indirect/global illumination with a single bounce.

Input	Output

Path Tracer

Implement path tracing and gamma correction.

Input	Output

Photon Mapping

Using Monte Carlo sampling for indirect/global illumination with a single bounce.

Input	Output

Final Project

Build own scene and apply rendering on it.
