Hi I am new to OpenGl, I tried to do a simple thing. Cube with text on the right. Problem is that when I risize window, cube is resizing too, but the text stay still in pozistion ?!? I change the resize code: glViewport (0, 0, (GLsizei)(width), (GLsizei)(height)); glMatrixMode (GL_PROJECTION); glLoadIdentity (); gluPerspective (45.0f, (GLfloat)(width)/(GLfloat)(height),0.1f, 100.0f); glMatrixMode (GL_MODELVIEW); glLoadIdentity (); and add a orto matrix: glViewport(0,0,width,height); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0.0f,640,480,0.0f,-1.0f,1.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); text is resizing and moving, but cube can be display in 2D :( How to resolve this problem ?>?

From what resolution to what resolution (I see 640x480 in there)?
How are you rendering text?

EDIT: Bitmap fonts? Never really used them, but I believe it won't scale. Where's the text-rendering code?
