My 10th project at 42 Network's Hive Helsinki 🐝

Simulating rays of light to render beautiful interactive scenes

eve_wallpaper.rt	inside_cylinder.rt
multicolored_lights_01.rt	Texture mapping example

This project's about raytracing, with the following base features:

• Parsing a scene (*.rt) file
• Scene validation
  • Has to have:
    • One point light
    • One ambient light
    • One camera
  • Can have:
    • Spheres
    • Planes
    • Cylinders
• Rendering a scene
  • Phong ambient & diffuse lighing model
  • Shadows cast by objects

We also wanted to create additional features for our own satisfaction and further learning:

• Optional project bonuses
  • Multicolored lights
  • Multiple point lights in the same scene
  • Extra 2nd-degree object (cone)
  • Specular highlights
  • Checkerboard pattern
• Additional extras
  • User inputs
    • Changing the viewpoint and object transforms (position, orientation, scale, FOV) live within the loaded scene
    • Toggling caps for cylinders and cones
    • Camera and object position and orientation upon manipulation
    • Resetting of camera and object transforms
    • Taking a screenshot of the current view
    • Window resizing with adaptive render region size
  • Extra patterns
  • Extra triangle object
  • Texture mapping onto objects and skybox
  • Multithreading for rendering optimization
  • Gradual rendering for faster viewport response
  • Scene file comments
  • Isolated testing for single objects

Dependencies:

• glfw

Run make or make optimized inside the repository root folder. The optimized rule uses several optimization flags.

In settings.h it is possible to set/control:

• Initial window resolution
• Input mappings
• Camera and object tranformation speeds
• Thread count
• Initial rendering precision
• Maximum rendering distance

./miniRT <path/to/scene_file.rt>

Example scene files can be found in the folder scenes inside the root repository folder. Refer to the example scenes for possible scene file entries (additionnal patterns, textures, parameters).

Recommended scenes:

• eve_wallpaper.rt
• incantation.rt
• stargate.rt
• crysis.rt
• triangles.rt

• Eve Keinan
• Johnny Varila
• 360 textures: PolyHaven
