Dear All,
I have a big problem with speed efficiency. I must display the dots on the
screen. However, monitor is 170Hz, and the best I can get, according to
VisionEgg is 160 frames per second. I changed the DotArea2D function to have as
few computation as possible, but I am still getting stuck on the following:
gl.glBegin(gl.GL_POINTS)
for i in xrange(len(xs)):
gl.glVertex3f(xs[i],ys[i],zs[i])
gl.glEnd()
especially when the dot arrays are big it takes long time for the frame to be
drawn. Is there a way I could somehow speed it up? As the dots I am displaying
do not move I thought I could have the frame somehow always drawn in the back
buffer and then just show it or not, is it possible??
I will appreciate any help,
thanks a lot,
Maria
