Hi!
Thanks for sharing the great work! I have a confusion that how did you implement trilinear interpolation on point clouds in the block of transition up. Because I think trilinear interpolation is a method on 3-dimensional regular grids.
Thank you!

Hi! I'm actually not the author of the paper

I was mainly interested in the "vector attention" proposed in the paper

So the author still didn't publish the original source code?😅

Thanks anyway.
