CPU Ray Tracer
Overview
- Period: October 2024
- Type: Personal project
- Objective: Implement a basic ray tracer that runs entirely on the CPU.
Implementation
- Implemented intersection tests for triangles, quadrilaterals, spheres, axis-aligned bounding boxes, cones, and cylinders.
- Implemented reflection, refraction, and shadow effects through ray tracing.
- Produced soft shadows by casting additional rays toward randomly sampled points around a light source.
- Loaded glTF files and rendered triangle-mesh data.
- Applied physically based rendering shading.
