# 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:
