Projection and animation of arbitrary number of objects given in obj format using a computer graphics technique called "Ray casting" to make them look realistic.

Refer the documentation for more details https://ksskreddy.github.io/RayTracing-on-Triangle-Meshes/

Input : Set of objects(in obj format), respective centers, scaling factors, colors, position of light and camera

Output: The scene as seen from the camera in a 500×500 PPM image

• The objects are assumed to be in a 500×500×500 room centered at (250,250,−250)
• So, the centers of the objects and their scaling factors must be chosen accordingly so that the objects don't go outside the room.
• The specifications like room size, output image dimensions can be changed by changing the macro WALL_SIDE in the tracer.h file.
• To turn off the effect of shadow of one object on another, the variable CrossShadows can be set to false.
