Pixel Coordinates for Ray Tracer 1

• Questions?
• Ray tracer 1.0
  • Setting up rays?
    
  • Turning ray(s) into image?
    

    for r = 1 : # rows
        for c = 1 : # columns
            create ray RR for pixel (r,c) (eqn f/ today)
            if RR intersects triangle (eqn f/ Wed)
                img(r,c,:) = triangle color
            else
                img(r,c,:) = background color

    • This is roughly my “snap” function
    • Except my “trace” function = “ray RR intersects triangle + if” part
  • Write more of the code
• Next
  • Transforming “canonical” objects
