raytracer1

This project was one of my graphical projects from my first year at EPITECH (2016-2017)

The goal of a raytracer is to draw 3D objects using raytracing.

This is a very basic raytracer, but I made later (in a group of 4 people) a more advanced version, available here.

Language: C

Group size: 1

Project duration: ~45 days (06/02/2017 - 19/03/2017)

Compilation: on GNU/Linux via Makefile

Required library: CSFML graphic library

To install it:

• on Debian / Ubuntu: sudo apt-get install libcsfml-dev
• on Arch Linux: sudo pacman -S csfml
• on other distributions, download it here

Usage:

./raytracer1 'scene.txt'

scene file:

The scene configuration file is composed of one or more objects.

Object values:

• obj: 1 (sphere), 2 (cylinder) or 3 (cone)
• trans: tanslation (X, Y and Z)
• rot: rotation (X, Y and Z)
• var: object size

All the elements (values and value names) must be separated by a newline.

All the objects must be separated by ******

Scene file example:

obj:
1
trans:
0
-220
-150
var:
60
******
obj:
2
trans:
0
200
0
rot:

0
0
var:
25
