What Is OpenGL?

OpenGL is a Graphics rendering API which is operating system independent, window system independent and has high-quality color images composed of geometric and image primitives.

OpenGL APIs can use following …

Gl

OpenGL API implementation (http://www.opengl.org)

Glu

OpenGL Utility

Glut – GLUT (OpenGL Utility Toolkit) – Glut is portable windowing API and it is not officially part of OpenGL.

OpenGL Utility Toolkit (http://www.opengl.org/resources/libraries/glut/)

FLTK

FlashLight ToolKit (http://www.fltk.org/)

GLEW…

Now lets see How to install OpenGL on out Ubuntu OS.

Now because GLUT (OpenGL Utility Toolkit) depends upon OpenGL and a number of other related libraries, if we install GLUT then OpenGL will be automatically be installed.

Run the following commands to install OpenGL.

$ sudo apt-get update

$ sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev

Now to test if OpenGl libraries are working fine on our Linux, we will create a C++ program and test it.

So create a following C++ Program.

#include

void displayMe(void)

glClear(GL_COLOR_BUFFER_BIT);

glBegin(GL_POLYGON);

glVertex3f(0.5, 0.0, 0.5);

glVertex3f(0.5, 0.0, 0.0);

glVertex3f(0.0, 0.5, 0.0);

glVertex3f(0.0, 0.0, 0.5);

glEnd();

glFlush();

>

int main(int argc, char** argv)

glutInit(&argc, argv);

glutInitDisplayMode(GLUT_SINGLE);

glutInitWindowSize(400, 300);

glutInitWindowPosition(100, 100);

glutCreateWindow(«Hello world!»);

glutDisplayFunc(displayMe);

glutMainLoop();

return 0;

>

Now give the command below to compile your code.

$ g++ main.cpp -o firstOpenGlApp -lglut -lGLU -lGL

Now run your OpenGl program with following command

$ ./firstOpenGlApp

Installing OpenGL and SDL on Linux Mint and Ubuntu

Installing OpenGL and SDL can be a right pain if you try to do it on windows especially if you are using Code::Blocks however on Linux Mint and Ubuntu it is exceptionally easy. Generally for programming and installing Libraries for C++ or modules for Python Linux is the easier option of the 2. This is due to the package manager system which Linux employs and because they are then available for your use so long as you know how to compile programs with them or have set your IDE up to use them in the project. For this example I am going to be using Code::Blocks.

SDL and OpenGL are the two foundations to making GUI programs. These two libraries make up the basics (although they are far from basic themselves) of GUI programming. Both are very powerful and when used together there is not much that cannot be accomplished with SDL being able to read keystrokes and mouse movements and OpenGL being the backbone of drawing graphics on the screen.

I’ve discussed how easy Linux is to use before however when installing OpenGL and SDL I found that I could not get my programs to compile on Windows meaning that when I am developing using these two libraries I use my Linux machine instead (in fact it is for this very reason that my Linux machine has once again become my more commonly used machine).

How do you install OpenGL and SDL on a Linux Mint or Ubuntu machine? Well four commands should do it however it is not so simple to compile so I think that will be a topic for Saturdays post.

Installing OpenGL and SDL is incredibly easy and here is how you do it:

sudo apt-get update sudo apt-get install libglm-dev sudo apt-get install libglew-dev sudo apt-get install libsdl2-dev

So that’s it. Those are the development libraries for OpenGL and SDL2 installed. I warn you though these are not the easiest of things to get started with and I would recommend that you proceed slowly and take your time when trying to learn these libraries although they are great fun to learn.
