[JOGL] Rotating text using Textrenderer

Question

Hey, I'd like to display text in a 2D szenario using JOGL. But I can't figure out, how to rotate text using com.sun.opengl.util.j2d.TextRenderer. It does not have any methods concerning the rotation. So I was expecting the modelview matrix to have an effect on the rotation.

val renderer = new TextRenderer(new Font("SansSerif", Font.BOLD, 36))

[...]

renderer.beginRendering(drawable.getWidth(), drawable.getHeight())
  gl.glRotatef(90,0,0,1)
  renderer.draw(content, 0, 0)
renderer.endRendering()

Do you know any help?

Answer 1

Call glRotatef before you beginRendering() the text.

Answer 2

Make sure to glMatrixMode(GL_MODELVIEW) just before calling glRotatef. You don't know what matrix mode the beginRendering method leaves OpenGL in.
