Naïve Renderer

This repo contains a naïve renderer that failed in the attempt to be photo-realistic. It is the final project for the Computer Graphics course.

Features implemented (listed in order of decreasing difficulty):

• Monte-Carlo-based path tracing
• Reflection, refraction, and diffusion
• Spherical texture mapping
• Image-based lighting (with strange artefacts)
• Anti-aliasing and depth-of-field

The following are some carefully-chosen above-average pictures rendered by this renderer:

• Cornell box with mirror, glass, and textured glossy spheres:

  

• Cornell box with mirror, glass, and metallic spheres:

  

• Cornell box demonstrating depth-of-field effect:

  

• Environment lighting using image-based lighting (with obvious artefacts) that took the least rendering time but looked the most impressive:
