[PyOpenGL-Users] getting the feedback buffer

[noema <mai...@sh...>]

This is driving me NUTTSS!!
no matter what I do I get a...

"Unknown vertex type in feedback buffer."

...when I try to switch back to glRenderMode(GL_RENDER).

Does anybody of you have a working example or can give me a hint to the 
problem...would really appreciate it!

In my draw methode I use the following code:

         glFeedbackBuffer(32768, GL_2D)
         glRenderMode(GL_FEEDBACK)

         # self._onDraw()
         glPassThrough(110)
         glBegin(GL_LINE_STRIP)
         glVertex3f(0.0, 0.0, 0.0)
         glVertex3f(1.0, 0.0, 0.0)
         glVertex3f(1.0, 1.0, 0.0)
         glVertex3f(-0.5, 1.5, 0.0)
         glVertex3f(0.0, 0.0, 0.0)
         glEnd()

         feedbackBuffer = glRenderMode(GL_RENDER)
