Current status

Basic raytracing model implemented
- Ray-sphere & ray-plane collisions
- Reflection
- Refraction
- Curved image plane (allows 360+ degrees field of view)
- Basic lighting model
Custom 3D vector math library
- vec3f, vec4f operations
- mat3, mat4 operations
- sin, cos, sqrt implementations
Custom image output library
- Generates 24bit color depth bitmap images (.bmp)

End goals

Functionality
- Reflection
- Refraction
- Shadows
- BRDF materials
- Multiple basic shapes (Sphere, ellipse, rectangular prisms, pyramids, etc.)
- Space partitioning
Small binary size
- Only C library function calls
- No external vector math libraries
Fast
- Multithreaded image generation
- Optimized intersection algorithms
