OOGL

OOGL (Object-oriented OpenGL) is a C++ library that wraps the functionality of the OpenGL API in a more object-oriented package. It additionally includes various classes and functions for 3D math, loading models and textures and creating a window and OpenGL context.

Quick start

To start using this library, all you need is Windows or a Linux distro and a working OpenGL driver that supports at the least OpenGL 3.2. Any libraries that OOGL depends on are included in the source, so building is as simple as

git clone git://github.com/Overv/OOGL.git
cd OOGL
make

or pressing F7 after loading the project in Visual Studio on Windows. To find out how to get started, have a look at the wiki.

Sample

To get an idea of what this library is like using in practice, have a look at the simple example below.

#include <GL/OOGL.hpp>
	 
int main()
{
	GL::Window window(800, 600, "OpenGL Window", GL::WindowStyle::Close);
	GL::Context& gl = window.GetContext();

	GL::Shader vert(GL::ShaderType::Vertex, "#version 150\nin vec2 position; void main() { gl_Position = vec4(position, 0.0, 1.0); }");
	GL::Shader frag(GL::ShaderType::Fragment, "#version 150\nout vec4 outColor; void main() { outColor = vec4(1.0, 0.0, 0.0, 1.0); }");
	GL::Program program(vert, frag);

	float vertices[] = {
		-0.5f,  0.5f,
		 0.5f,  0.5f,
		 0.5f, -0.5f
	};
	GL::VertexBuffer vbo(vertices, sizeof(vertices), GL::BufferUsage::StaticDraw);
		
	GL::VertexArray vao;
	vao.BindAttribute(program.GetAttribute("position"), vbo, GL::Type::Float, 2, 0, 0);

	GL::Event ev;
	while (window.IsOpen())
	{
		while (window.GetEvent(ev));

		gl.Clear();

		gl.DrawArrays(vao, GL::Primitive::Triangles, 0, 3);

		window.Present();
	}

	return 0;
}

The sample above makes use of a lot of the abstraction OOGL offers, but it is always possible to fall back to the raw OpenGL calls.
