Soft

Simple 2D Real-Time Graphics Library

Introduction

This project was created purely for learning purposes. It allows me to get the deeper knowledge of how to graphics programming work under the hood. The big source of information was raylib, a simple and easy-to-use library to enjoy videogames programming. All of the external sources I've used are mentioned as the coude blocks in the soft.c implementation file. My main inspirations were:

• "olive.c" by Tsoding.
• "Programming a first person shooter from scratch like it's 1995" by Jdh.

Example

#include "soft.h"

int main(int argc, char** argv) {
    softInit(1024, 768, softTextFormat("Soft %s", SOFT_VERSION));

    while(!softWindowShoulClose()) {
        softClearBufferColor(WHITE);
        softDrawCircle((Circle) { softGetWindowCenter(), 100 }, RED);

        softBlit();
    }

    softClose();

    return 0;
}
