Argyriou","doi":"10.1145/3415264.3425443","DOIUrl":"https://doi.org/10.1145/3415264.3425443","url":null,"abstract":"Leaps in technology are increasingly making the prospect of using biological structures as part of digital models and artwork a tangible reality. In this work a new method heavily inspired by natural biological processes for 3D modelling and animation is proposed. The proposed approach differentiates from the classic assembly or printing methodologies and offers a novel growth based solution for the design and modelling of 3D structures. In order to facilitate the needs of growth based modelling, new terms and graphic primitives such as stem-voxels, muscle-voxels, bone-voxels and digital-DNA are introduced. The core production rules of a novel context free grammar were implemented allowing 3D model designers to build the digital-DNA of a 3D model that the introduced parser will interpret to a full 3D structure. The obtained 3D models support animation using the muscle-voxels, they are able to observe the environment using photoreceptor-voxels and interact with a level of intelligence based on neural networks build with nerve-voxels. The proposed solution was evaluated with a variety of volumetric models demonstrating a strong potential and impact, with many applications and offering a new tool for 3D modelling systems.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128048727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little research has focused on examining backward movements. Inappropriate support of such movements could lead to dizziness and disengagement in a VR program. In this paper, we investigate the possibility of detecting forward and backward movements from three different positions of the body (i.e., head, waist, and feet) by conducting a user study. Our machine-learning model yields the detection of forward and backward movements up to 93% accuracy and shows slightly varying performances by the participants. We detail the analysis of our model through the lenses of body position, integration, and sampling rate.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121222159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main idea is to add details into a coarse 3D Morphable Model (3DMM) based model in a self-supervised way. Our observation is that most of the facial details like wrinkles are driven by expression and intrinsic facial characteristics which here we refer to as the facial attribute. To this end, we propose an expression related details recovery scheme and a facial attribute representation.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115463395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these are surfaces viewed from Earth, and we cannot understand the relative distances between celestial objects in three dimensions. Therefore, in this study, we developed a system to determine such distances by placing the stars in a virtual space. The system allows users to move freely in a large scale of space using a game engine and the Hipparcos catalog. We can intuitively perceive the relative distances of stars by understanding the three-dimensional configuration of the stars and constellations as seen from Earth.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127657349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present an end-to-end system that is designed for casual creation of real-world VR content, using a smartphone. We use an AR app to capture a linear light field of a real-world object by recording a video sweep around the object. We predict multiplane images for a subset of input viewpoints, from which we extract high-quality textured geometry that are used for real-time image-based rendering suitable for VR. The round-trip time of our system, from guided capture to interactive display, is typically 1–2 minutes per scene.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115263519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These methods can generate a realistic 3D human model from an image by focusing on the body shape. However, it may be difficult for these methods to generate a user-desired 3D character model from a character illustration. In character illustrations, each character has unique features especially in the lengths of their body parts. To reflect these unique features on 3D models, in this paper, we propose a novel interactive 3D model generation method from character illustrations. Our method modifies 3D models to match the user’s intentions interactively based on the constraints of input poses and symmetrical bone lengths. The experimental results show the effectiveness of our method.","PeriodicalId":372541,"journal":{"name":"SIGGRAPH Asia 2020 Posters","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116110651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
