PIFuHD

PIFuHD: Multi-Level Pixel-Aligned Implicit Function for High-Resolution 3D Human Digitization.

PIFuHD a machine learning model for generating 3D reconstructions of human bodies from a single image it was developed by researchers at Reality Labs (Meta Platforms of Facebook) and the University of Southern California. And it was published in a paper in the proceedings of the IEEE conference on Computer Vision and Pattern Recognition in 2021.

PIFuHD can be a useful tool for 3D artists in a number of ways as a machine learning model it uses a combination of neural networks and optimization techniques to reconstruct the 3D geometry and texture a process body from a single 2D image which is really interesting saving you time and effort of manually creating 3D models from scratch. and this hopefully will get even better because Meta is actively working on their metaverse. the 3D models produced by PIFuHD are relatively of high quality with detailed skin hair and clothing. this can make it easy easier for you to create high quality 3D models of people quickly and efficiently without having to spend as much time modeling and texturing individual details.

Additionally the models are produced by PIFuSD can be used as a starting point for 3D sculpting in addition to other stuff. For example you can use PIFUSD model as a base mesh and then add additional details using sculpting software such as zBrush or Blender.

Even though PIFuSD is just in the early stages and it is not being used at the Practical level yet, it can potentially speed up the overall modeling process and allow you to focus on more creative aspects of your work in the future. it also has the potential to greatly improve the efficiency and accuracy of 3D character modeling and animation particularly in fields such as VR and AR. Especially knowing that meta is currently working on their metaphors and they already have the Oculus VR headsets which means they probably have big plans when it comes to this technology.
