Doug,

You could use pfuSaveImage in a draw callback,

man pfuSaveImage yeilds....

int    pfuSaveImage(char* name, int xorg, int yorg, int xsize, int ysize,
              int alpha);

Use it in a draw callback like this....

void DrawChannel(pfChannel *channel, void *data)
{
     char fileName[64];

    sprintf(fileName, "frame%03d.rgb", pfGetFrameCount());

    /* erase framebuffer and draw Earth-Sky model */
    channel->clear();

    /* invoke Performer draw-processing for this frame */
    pfDraw();

    pfuSaveImage(fileName, 0, 0, 1024 , 1024, 0);

    /* draw Performer throughput statistics */
    if (drawStats)
        pfDrawChanStats(channel);
}

You have to setup your channel(s) to call the callback.....

    pfChannel *achan = new pfChannel;

    achan->setTravFunc(PFTRAV_DRAW, DrawChannel);

I must warn you copy back of the framebuffer is painfully slow. The best way to
do this is send it to video and save it on a video tape. If you are just
copying a frame or two it won't be to bad. Perfly has a feature which uses
pfuSaveImage() to copyback frames when you hit a key stroke.
