Hi I am new to Performer and I have a few questions concerning pfLighPoint.

1) How to specify a light point that has a 10 pixels coverage on an Indy ?
    Because I tried the following command :

         pfLPointSize(lpoint, 10.0f);

    but the LPoint still shows as if it was 1 pixel wide. I know that
    this command passes 10.0f as the argument to the pntsizef GL routine
    but according to the man pages most SGI machines cannot display
    point that have more than one or two pixels.

2) Let say there is a runway light string made of 10 lights and each of
    these lights nees to be, in sequence, turn on each 0.05 seconds and
    must stay on for 0.01 seconds. Using pfLightPoint, how should this
    kind of animation be implemented. If you have source code that does
    something like this I would like to take a look at it !

Thanks in advance !
