+# Fonts
+
+
+
+
+## High Level Overview
+The font loading mechanism loads all fonts at engine startup. It leverages java.awt.Font to read font data from ttf files on disk, render them to a bitmap, and then display appropriately.
+Globals has a font manager that can be leveraged to get fonts based on identification strings.
+
+
+

+## Major Usage Notes

+
+
+## Main Classes
+
+[Font.java](@ref #electrosphere.renderer.ui.font.Font) - Holds all the data about a font: the glyphs and metadata about them, as well as the material containing the actual bitmap
+
+[FontManager.java](@ref #electrosphere.renderer.ui.font.FontManager) - Keeps track of all fonts loaded into the engine.
+
+[FontUtils.java](@ref #electrosphere.renderer.ui.font.FontUtils) - Utilities to load fonts from disk
+
+[BitmapCharacter.java](@ref #electrosphere.renderer.ui.font.bitmapchar.BitmapCharacter) - The main rendering component for text. Renders a single character of text based on a given font, font size, and character.
