I was searching to find a suitable method for rendering text in DX11.
http://rastertek.com/dx11tut12.html was best way but it has some limitations and extra works:
1-Creating Font atlas for an artist is a hard work.
2-This sample did not used some Dx11 ability such as Geometry Shader witch is very suitable to rendering font.
3-This sample implements text in screen space not in world space.
also I do not recommend that you use this method :
This lib create an extra device 9 or 10 to create DirectDraw thus it is a 2D font system and you can not use some debugging tools such as PIX and VS 2012 Diagnostics.
