I tried using the font tutorials(lesson 17)to display some text with my 3d program. Basically,I wanted to display a 3d coordinate sistem and some simple 3d functions in it,and then to display content rotation and translation matrix (using less 17 source code),dut when I tried to draw something it doesn''t show up...I noticed that it shows up when I disable loadin textures,but without them I can''t display fonts,and also need textures fo matrix borders. I tried adding code to lesson17 source,but still same thing happens. Any idea what I should do,I would be thankful.
