Overview#

A ray tracing engine implemented from the ground up, using only pixel-level rendering to create realistic lighting effects. Features Phong shading, multiple geometric primitives, and mirror reflections; all built from mathematical first principles.

Key Concepts#

• Built complete ray tracer from scratch using only setPixel() function
• Implemented Phong lighting model with ambient, diffuse, and specular components
• Built ray-object intersection algorithms for spheres, circles, planes, and cylinders
• Calculated surface normals for correct lighting on each primitive
• Added mirror reflections with recursive ray casting
• Applied vector mathematics (dot products, normalization, reflection) throughout
