simple raytracer in python using numpy and vectorization concept

The goal of this project is to write a simple raytracer. That is, a program that takes a 3D model and generates an image of what it looks like from a particular camera angle (this is called rendering). In this case the 3D model will be represented by a signed distance function, which makes rendering particularly easy. The purpose of this project is to vectorise the code given which is just replacing simple and few for loops with numpy functions to make it runs faster.
