The proper way of getting C2W matrix from self.world_view_transform?

Hi,

thanks for your amazing code work, we are able to access to W2C matrix(= self.world_view_transform) here.

However, the code for the function getWorld2View2 is very tricky; The function that I'm confused with the way of getting the proper C2W matrix from self.world_view_transform.

Do I need to 1. transpose 0th and 1st dimension against self.world_view_transform and 2. apply the inverse function (just following the exact reverse step)?

Thanks, Junyeong Ahn
