Why take negative for transformed_vertices #5

Hello!

Amazing work!

Why take negative for transformed_vertices：transformed_vertices[:, :, 1:] = -transformed_vertices[:, :, 1:]

Hey, thanks for liking SMIRK ! The flipping in these axes is needed before rendering the model so that it is in proper format for pytorch3d.
