title: Best way to convert OpenGL immediate mode rendering utility methods to using VBOs?
body: <p>I've written for myself a small utility class containing useful methods for rendering lines, quads, cubes, etc. quickly and easily in OpenGL.  Up until now, I've been using almost entirely immediate mode, so I could focus on learning other aspects of OpenGL.  It seems prudent to switch over to using VBOs. However, I want to keep much of the same functionality I've been using, for instance my utility class.  Is there a good method of converting these simple immediate mode calls to a versatile VBO system?</p>
  
  <p>I am using LWJGL.</p>
