In this assignment, you will implement ray casting algorithm.
Follow the lecture content, write a program to generate the ray casting result.
The objects in the scene are spheres. You need to define in your program:
the light source intensity (R, G, B),
light source location (Lx, Ly, Lz),
eye location (Ex, Ey, Ez),
at least 2 spheres,
location/radius of spheres,
surface property (K value in the lighting model), view plane size/location/orientation (perpendicular to one axis)
Your result should be showing 2 shaded spheres (or more), with one sphere casting a shadow on the other
( after your program works, just change the sphere location or light location to get shadow)
ground plane is optional. Reflection and refraction are optional.
A diagram image is provided for your reference.
Write comment to explain your code.
