Edit Question
Title
Body
There are already a number of questions about text rendering in OpenGL, such as: How to do OpenGL live text-rendering for a GUI? But mostly what is discussed is rendering textured quads using the fixed-function pipeline. Surely shaders must make a better way. I'm not really concerned about internationalization, most of my strings will be plot tick labels (date and time or purely numeric). But the plots will be re-rendered at the screen refresh rate and there could be quite a bit of text (not more than a few thousand glyphs on-screen, but enough that hardware accelerated layout would be nice). What is the recommended approach for text-rendering using modern OpenGL? (Citing existing software using the approach is good evidence that it works well) Geometry shaders that accept e.g. position and orientation and a character sequence and emit textured quads Geometry shaders that render vector fonts As above, but using tessellation shaders instead A compute shader to do font rasterization
