ApolloRaytracer

A hobby Blinn-Phong shaded ray-tracer written in C++

Features

• Octree mesh acceleration
• Basic multithreading
• JSON scene loading
• SDL2 Window output
• Keyboard controls
• Blinn-Phong shading
• Reflections
• Refractions
• Sphere geometry
• Triangle geometry
• Mesh geometry / model loading
• AABB for mesh-ray collisions
• Environment mapping
• Basic material system
• ASCII output (doesn't play well with environment mapping, works better if you decrease terminal font, can be enabled in ApolloRaytracer.cpp)
• Multiple cameras and ability to cycle through them

Controls

• WASD to move
• QE to move up and down
• arrow keys for camera rotation
• space bar to cycle through cameras in scene
