add point cloud for gaussian splatting initialisation

[benoitmar]

Hello,

From what I've understood, when creating gaussians splatting, it's important to have the position of the cameras but also useful to have a point cloud to start the initialization. However, I'm surprised to see that when I run a training session, there's no initialization point.
Is it possible to add one, in what format? With which command line?
I'd like to export this cloud from reality capture.
Thanks for your help.
