Help With graphics

SDL Development

Hello all,

I am trying to make a sort of a graph with SDL

What i wanted to ask was if there is a pixel pointing mechanism in SDL to
use.I had thought of putting values in the equation and then simply plotting
the pixel to generate a graph.

Also if you could tell me if there is another method to draw curves besides
the above.

I have another thing to ask which is that the graphics move in SDL very
slowly.Is that normal or can I change the output to smooth graphics??

Thanks…

Several years ago, I wrote a polynomial graphing program for my students. If
you think it would be useful for what you want to do, let me know and I’ll
send you the tar.gz file (C++ source, 57KB).
