does anyone know how to use multiple layers with an alpha colour set so that I can place text on top of the OpenGL rendered graphics?
also does anyone know if it is possible to only let OpenGL render to a part of the screen and use the other parts from another layer? (like a sub-window rendered in GL and other sub-windows using pygame)

Note: I can't use screen.blit(source,rect) since an OpenGL enabled screen can't be blited... instead I use pygame.display.flip()

here is the basic code I use:
---------------------------
import OpenGL, pygame
from pygame.locals import * # used for variables
from pygame.display import flip # put the GL buffer to screen
from OpenGL.GL import *
from OpenGL.GLU import *

pygame.init() # init pygame

win_size =(640,480)
flags=OPENGL|DOUBLEBUF
screen = pygame.display.set_mode(win_size, flags) # set up for OpenGL

glEnable(GL_DEPTH_TEST) #GL related functions, nothing to do with pygame
glMatrixMode(GL_PROJECTION)
gluPerspective(45.0,float(win_size[0])/win_size[1],0.1,100.0)
glClearColor(1.0,0.0,0.0,0.0) # set background as red

while 1: #THE FOLLOWING MUST BE INDENTED,THE BOARD DOEST SHOW SPACES
pygame.event.poll() # clear the input buffer, stops it from overloading
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT) # set buffer to red
flip() # switch buffers... or blit buffer to screen

I haven't played with surfarray myself so I don't know how well it works with text.

PS> You can use tabs and spaces in your code by putting your source code in

[ code ] [ / code ] UBB code tags (remove spaces) def foo(bar): print bar foo() #As you can see, spaces are not removed

I got text semi-working in PyOpenGL and PyGame.....

turns out that there is no documentation for this and that the only way to draw text on the screen is to render an image from text and then place this image as texture on an object in OpenGL

if anyone wants the code, just ask
