This was a project for Graphic Computation subject and now it is online to assist other students with any doubts they may have with C language and OpenGL api.
Use the Makefile to compile the project by typing make into the command line prompt then run the file using the space executable file. Main file is space.c
To run this arguments, type as follows on the command-line prompt: ./space <args>. Instead of , choose one or more of the arguments listed below. Default values can be found on spacedef.h file.
Note: this project does not follow the Unix command-line patterns, instead the argument's name is an abbreviation of what the command does.
- -ep Displays the path of the planes.
- -ns Disables the stars.
- -dpf=<double_value> Days per frame. Higher values means faster simulation (the planets will move faster).
- -ss=<double_value> Size scale. Higher number means bigger planets.
- -ds=<double_value> Distance scale. Higher number means bigger distance between the planets.
Commands listed below, use capital letters to move faster.
- Horizontal move: w, a, s, d.
- Vertical move: e, q.
- Look around: click and drag the mouse to the direction you want to look. This feature needs improvements.
- The planets do not spin around itself.
- Gravity not implemented as was supposed to be (removed).
The star.c file was used to inspire the author of this project on how to create the moving "space dust" you see in this project.
Comments are in Portuguese-BR, some parts of the code are not commented since this code was not intented to be distributed, it was just a homework. The purpose of this repo is to assist others and not to teach how to create a solar system using C language (improvements in comments should not be expected).
