OK, my first problem, but it is probably because I am an OpenGL noob.
;) I thought it would be neat to display the FPS on my samples but no
matter what I do I can't seem to get it to appear. It seems that if I
do not wire up my "on_resize" function that sets up my OpenGL viewport
and perspective, the FPS display shows up (but my geometry - a simple
spinning triangle - doesn't appear). But if I hook up my on_resize
function to my window so I can see my geometry, the FPS display is
never rendered.
Here is my on_resize() function:
def on_resize(width, height):
if height == 0:
height = 1
glViewport(0, 0, width, height) # reset the viewport to new dimensions
glMatrixMode(GL_PROJECTION) # set projection matrix current matrix
glLoadIdentity() # reset projection matrix
# calculate aspect ratio of window
gluPerspective(52.0, width/height, 1.0, 1000.0)
glMatrixMode(GL_MODELVIEW) # set modelview matrix
glLoadIdentity() # reset modelview matrix
Sorry if this is obvious to everyone else and I just need to go and
learn more about perspective and projection matrices. If you can't
tell, I'm an OpenGL noob...
Thanks,
M.
