Motivation

Our team all had an interest in computer graphics in general and wanted to use this oppoturnity to implement a project that we all like, that being the process of rendering, specificly the ray-tracing rendering process.

Thanks to the analysis with much studies through documents and a whole lot of physics, every member on the team can recognize and understand its core problems, solutions, methodologies and implemented it with small inputs and libraries together.

🧮 General Information

• GUI : Simple GUI implemented through Netbean IDE.
• Renderer : The raytracer implemented from stratch using vecmath library.

📋 Features

List the ready features here:

Field	Functions
Scene	Add light - Import mesh - Import scene - Duplicate mesh - Remove light, mesh - Save scene - Load scene
Object	Change name - Translate position - Transform scale - Change object settings (color, reflection, refraction, etc..)
Camera	Change position - Change target - Change vector up - Change field of view - Targer an object
Render	Change window height and width - Change shadow type - Antialiasing amount - Acceleration - Output image

💼 Acknowledgement

• With deep gratitude and respect, we acknowledge the professional guidance of Dr. Nguyen Van Sinh and Dr. Le Duy Tan. The constant support and knowledge provided by the course helped us achieve our goals of successfully implenting the renderer.

Future Features

• Rotation transform
• Render more complex meshes
• An easier way to move objects and the camera
• More optimization
• Real time render
