This repository contains the official implementation for the paper: TightCap: 3D Human Shape Capture with Clothing Tightness Field (SIGGRAPH 2022). Our work is capable of capturing both the human shape and dressed garments accurately with only a single 3D human scan.

Abstract

In this paper, we present TightCap, a data-driven scheme to capture both the human shape and dressed garments accurately with only a single 3D human scan, which enables numerous applications such as virtual try-on, biometrics, and body evaluation. We propose a new clothing tightness dataset (CTD) of human scans with a large variety of clothing styles, poses, and corresponding ground-truth human shapes to stimulate further research. Extensive experiments demonstrate the effectiveness of our TightCap to achieve the high-quality human shape and dressed garments reconstruction, as well as the further applications for clothing segmentation, retargeting, and animation.

The CTD Dataset

TightCap proposes a new clothing tightness dataset (CTD) of human scans with a large variety of clothing styles, poses, and corresponding ground-truth human shapes to stimulate further research.

Download

You can download the CTD dataset (version 1.0) with the static/dynamic part from the OneDrive links. Please unzip each part with all downloaded volumes.

CTD_Static_part (20GB, 228 different garments) The static meshes, various clothed humans with segmented top/down clothing/shoes and carved bodies.
CTD_Dynamic_part (15GB, 652 annotated meshes from dynamic 3D human sequences, 13 sequences in total) The dynamic meshes, per-frame clothed humans with segmented top/down clothing/shoes and carved bodies.

Annotation

The CTD dataset contains various and rich annotations for different 2D/3D vision and graphics tasks, like human generation, body estimation, pose retargeting, clothing segmentation, virtual try-on, neural rendering and so on. The high quality textures support re-rendering multi-view virtual input images for algorithm verification and quantitative experiments.

For the static part, each folder (named with the mesh code, see below) includes naked, top, bottom, shoes and original textured mesh. We visualize all meshes for preview and provide the mesh part annotation in meshcode_labelsV.txt.

f: female, m: male
c: coat, d: dress, t: t-shirt, p: pants

For the dynamic part, each sequence also includes naked, top/bottom, and original textured mesh. These annotated frames are selected from original dynamic clip under 30 FPS. We also visualize these meshes. Moreover, we will release these dynamic sequences soon, and you can refer to Multi-view Neural Human Rendering (NHR) for more dynamic mesh sequences and the code for neural human rendering.

Tools - DomeViewer

DomeViewer is designed to support CTD dataset based on Unity3D engine, which can play 4D free-viewpoint video with dynamic mesh sequences. You can freely pause, play and fast forward the model after loading, and unlike traditional videos, you can control the rotation of the viewpoint with the right mouse button to experience 4D video clip.

Tools - Dataset

The tools folder includes the index lists for mesh details.
