how does poser treat first frame

i have been working on an animation editor that i plan to release soon, after i have ironed out a few rough spots. one that i have not resolved yet is how to treat the first frame which SL uses as a baseline, but does not display.

i do not have a copy of poser, so i would appreciate it if someone would tell me how poser handles this. the way i see it, i could approach this in several ways:


1. always assume that the first frame is not to be shown, and skip over it when playing the animation, but have a menu item that allows the user to override this.

2. assume that a first frame will be added by the user when saving the bvh file. (let me explain: my program deals with *projects*, and doesn't actually save a bvh file until you tell it too. it always saves all your work in a project file in any case). also assume that the user will, if necessary, delete the first frame when loading a bvh file.

3. automatically add a first frame whenever a bvh file is saved, and delete it whenever a bvh file is loaded, or popup a dialog box asking the user for input in these cases.

how do poser users handle this?

thanks,

1st frame is just reference, nothing more..so leave as default SL avie, not moved.

So when i start a new animation I move to frame 2 and start my animation, don't even look at frame 1.

ahhh, thanks alot. thats exactly what i couldnt understand. thanks man.
