RayDream

A photorealistic raytracer and editor designed to create stunning rendered images with ease and flexibility. Featuring an intuitive interface for editing objects, importing models, and adjusting raytracer settings.

Features

• Photorealistic Rendering: High-quality raytracing for realistic lighting, shadows, and reflections.
• Acceleration Structures:
  • Bounding Volume Hierarchies (BVH): Speeds up rendering by optimizing object intersections.
  • Adaptive Supersampling: Enhances image quality by dynamically refining pixel sampling in detailed areas.
  • Multithreading: Leverages multiple CPU cores for faster rendering.
• GUI and Editing:
  • Object Editing: Modify object properties such as position, rotation, scale, and material.
  • Settings Panel: Adjust rendering parameters like resolution, recursion depth, and lighting settings.
  • Model Import: Load and integrate OBJ models, complete with support for:
    • Textures: Apply image-based materials to models.
    • Bump Mapping: Add surface detail for increased realism.

Images Rendered with RayDream

Getting Started

Prerequisites:

• Apache Maven
• Java JDK 22 or greater
• A system that supports OpenGL and the latest graphics drivers installed

Compile and Run

1. Clone the repository:

   git clone https://github.com/JacksonHoggard/raydream.git
