title: Is it possible to 'manually' create image data for OpenGL texture use?
body: <p>I'm learning about textures in the OpenGL environment. I see there's no conventional way of acquiring the actual image data before passing it to video memory.</p>
  
  <p>Out of curiosity, is it possible to create my own matrix of pixel data and fill it in with arbitrary information instead of actually reading a bitmap or an image file?</p>
