PeeledHuman [3DV 2020] PeeledHuman: Robust Shape Representation for Textured 3D Human Body Reconstruction AbstractWe introduce PeeledHuman – a novel shape representation of the human body that is robust to self-occlusions. PeeledHuman encodes the human body as a set of Peeled Depth and RGB maps in 2D, obtained by performing raytracing on the 3D body model and extending each ray beyond its first intersection. This formulation allows us to handle self-occlusions efficiently compared to other representations. Given a monocular RGB image, […]

pyslm PySLM is a Python library for supporting development of input files used in Additive Manufacturing or 3D Printing, in particular Selective Laser Melting (SLM), Direct Metal Laser Sintering (DMLS) platforms typically used in both academia and industry. The core capabilities aim to include slicing, hatching and support generation and providing an interface to the binary build file formats available for platforms. The library is built of core classes which may provide the basic functionality to generate the scan vectors […]

soroban-parametric-cadquery A parametric soroban written in CADQuery The purpose of this project is to demonstrate how “code CAD” can be intuitive to learn. See soroban.py for a self-contained example. See src/ files for realistic structuring of a code CAD project. Splitting up parts into their own files makes them reusable across designs and allows for easy modification. Here are a couple pictures of the soroban: How it’d look in a slicer: Follow the CADQuery installation instructions, and open the soroban.py […]

3D Multi-Object Tracker This project is developed for tracking multiple objects in 3D scene. The visualization code is from here. Features Fast: currently, the codes can achieve 700 FPS using only CPU (not include detection and data op), can perform tracking on all kitti val sequence in several seconds. Support both online and global implementation. The overall framework of design is shown below: Kitti Results Results on the Kitti tracking val seq [1,6,8,10,12,13,14,15,16,18,19] using second-iou and point-rcnn detections. We followed […]

part-based-scan-understanding Towards Part-Based Understanding of RGB-D Scans (CVPR 2021) We propose the task of part-based scene understanding of real-world 3D environments: from an RGB-D scan of a scene, we detect objects, and for each object predict its decomposition into geometric part masks, which composed together form the complete geometry of the observed object. Download Paper (.pdf) Demo samples Get started The core of this repository is a network, which takes as input preprocessed scan voxel crops and produces voxelized part […]

FreeCAD This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler. Freedom to build what you want FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history to change its parameters. Create 3D from 2D and back FreeCAD lets you to sketch geometry constrained 2D shapes and use them as a base […]
