RayTracingJS

Implementation of recursive ray tracing algorithm using p5.js library available at Ekan5h.github.io/RayTracingJS

Sample Outputs:

To create custom scenes:

• Change the eye position by changing the variable eye
• Change the window position by changing the variable screen which contains the four corners of the window.
• Lights can be positioned in the lig list while their brightness can be changed by changing intenstity
• Objects can be added to the scene in the objects list.

Currently, only sphere and floor classes are added.

To add more shapes:

• Create a class with data members: color, e (Emmisivity) and r (Reflectance) such that [e + r = 1]
• A shape should have the member functions:
  • intersect(start, dir): Return true if a ray starting at start in direction dir intersects the shape else return false.
  • getPoint(start, dir): Return the point of intersection of the ray starting at start in direction dir
