Character Rendering with FreeType and OpenGL: Bitmap Font Generation, Texture Creation, and Caching Mechanism

The article explains how to use FreeType to load and render font glyphs into bitmaps, upload those bitmaps as OpenGL textures, render them with texture coordinates, and employ a bitmap cache and fixed‑size texture atlas to efficiently manage and reuse character images in a fast double‑buffered text rendering pipeline.
