title: Open GL draw static Points
body: <p>Is it posible to draw a static Point-Cloud in Open-GL</p>
  
  <pre><code>glBegin(GL_POINTS);
  
  for(float x = -1; x &lt; 1; x += 0.1) 
  {
      for(float y = -1; y &lt; 1; y += 0.1) 
      {
          for(float z = -1; z &lt; 1; z += 0.1)
          {
              float d = 1-sqrt((x * x) + (y * y) + (z * z));
              glColor3f(d, d, d);
              glVertex3f(x, y, z);
          }
      }
  }
  
  glEnd();
  </code></pre>
  
  <p>and later to e.g. rotate around this Cloud ? Without drawing it everytime again ?</p>
