1. Do you know the anti_aliasing option in the resize function supports 3D volumes?

Yes, it is supported in 3D (and more generally in nD as long as the dtype is not boolean). If left at the default of None anti-aliasing will be applied if any dimension of the array is being downsized. The actual antialiasing applied is just a call to a separable nD Gaussian filter from CuPy. If it is desired to only smooth along with a subset of axes, the user would have to specify anti_aliasing_sigma and set the sigma value to 0 for any axes where anti-aliasing should not be applied.
