In this post we will see how to install OpemGL on Ubuntu.In order to install OpenGlL you need to type only few commands .Here we will be looking at step by step process to install OpemGL:
1.First open your terminal and update the repository using command : $ sudo apt update
After entering your password your update will be done .
2.In this command your installation will be completed.Type the following command : $sudo apt-get install freeglut3-dev
After completion it will look like this :
.
3. 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 <GL/glut.h>
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
OUTPUT:
If a window pops up when you run the program, then OpenGL is working on your Ubuntu OS.In this way , following these steps you will be able to install OpenGL and use it.
