Another new tutorials is finally available at GitHub! In this part we look into using textures with shaders.
In an sub-part of the tutorial it is explained how to use textures to do font rendering in OpenGL!

Now a quick overview what to learn in the new tutorials:

Texture tutorial

• Creating textures
  • Wrapping
  • Filtering
  • Uploading the pixel data to the GPU
• Using the texture in shaders

Font tutorial

• Creating a texture atlas
  • Loading TrueType Fonts
  • Determine width and height for the texture
  • Generating the texture and draw font glyphs on it
• Rendering the text

That font rendering part is already using batch rendering, so the next tutorial will be about how to create a batch!
