4.1.3. Combining textures in a texture atlas

To assist with the process of combining triangles, you can combine multiple textures together into a texture atlas. This is a single texture image that contains textures from components of different objects.

If you are drawing text on screen you use the same technique. Combine all the drawing calls into a single call and use a font atlas to provide the font images. This is an efficient technique because it enables you to draw all the text in a single draw call.

Note

Texture atlas based techniques typically do not work with repeating textures.
