Displaying text in OpenGL

Hello,

As in title, I would like to display text in OpenGL, the "right" way (https://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_Text_Rendering_01).
Basically, there is one texture acting as cache for all glyphs actually displayed on screen, and we render one quad per glyph, with proper texture coordinates.

Is there any such texture atlas implementation yet atop FreeType?

Cheers,

This the approach that Cairo uses to work with OpenGL. Cairo is doing very good job at rendering fonts. Athens wraps Cairo, so maybe if you use Athens with a modern wrapper of OpenGL for Pharo this will save all the trouble of doing it from scratch. But I have not tested this in practice so I offer no promise it will be that easy.
