Insight

Insight is lightweight, data oriented game engine and framework written in C99. The engine is designed to be fast and could be used in any project and, also, it could be easily implemented with C++. The only dependecies it needs are an GLFW and OpenGL library and stb_image and stb_image_write header files.

The engine is designed with speed in mind, and does all the work for you have to use data oriented aproach.

Features:

• Lightweight
• Use only what you need
• Written in C99
• Small codebase (~1kLOC)
• Simple and portable
• Documentation (In development)

Building

This library is written in a single header file, there is no need of buildage.

You would need to implement the headers files like this:

#define INSIGHT_WINDOW_IMPL /* Implements all the window functions */
#include "Window.h" 

Examples

Insight Init:

#define INSIGHT_INSIGHT_IMPL
#define INSIGHT_WINDOW_IMPL
#include "Insight.h"
#include "Window.h"

int main(void) {
	if (!INSIGHT_EASY_INIT()) {
		return -1;
	}
	
	Insight_Window* wnd = insight_window(1280, 720, "Hello, World!!!", INSIGHT_FALSE);
	assert(wnd);
	
	while (insight_window_running(wnd)) {
		glClear(GL_COLOR_BUFFER_BIT);
		glClearColor(1.0F, 0.0F, 0.0F, 1.0F);
	}
	
	insight_window_finalize(wnd);
	INSIGHT_EASY_TERMINATE();
	return 0;
}

Dependencies and Suggestions:

• GLFW https://www.glfw.org/
• OpenGL https://glad.dav1d.de/ or http://glew.sourceforge.net/
• stb_image https://github.com/nothings/stb/blob/master/stb_image.h
• stb_image_write https://github.com/nothings/stb/blob/master/stb_image_write.h

Compilation (With GCC)

If you are using GLAD

gcc main.c glad.c -I[path to the includes] -L[path to the linkers] -glfw -opengl32

If you are using GLEW

gcc main.c -I[path to the includes] -L[path to the linkers] -glfw -opengl32 -glew32
