In order to solve this problem, we propose a novel rendering framework, where the server renders RGB-D images of a 3D model with the optimally arranged rendering viewpoints, and the client HMD realizes geometric compensation of M2PL by employing depth image based rendering (DIBR). Experiments with real smart glasses show that the proposed method can display binocular images closer to the ground truth than the conventional approaches.","PeriodicalId":199099,"journal":{"name":"SIGGRAPH Asia 2021 Posters","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122941118","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}

In this study, we investigated the effect of shadows on the perception of the shape of a mid-air image by projecting shadows of different shapes onto a mid-air image that is displayed in real space. Specifically, participants viewed one oval cylinder with a shadow and one oval cylinder without a shadow individually and were forced to choose which had the greater thickness in the depth direction. As a result, we found that shadow shapes possibly changed the perception of the thickness of the mid-air image.","PeriodicalId":199099,"journal":{"name":"SIGGRAPH Asia 2021 Posters","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131557924","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}

Previous approaches synthesize the sound for fluids by physically-based simulation, but these approaches need a huge computational cost. To address this, we propose a data-driven method for synthesizing sound effects for fluids. In this paper, we focus on liquid sound. A liquid sound database which consists of a set of recorded sound clips is prepared in advance, and then the most suitable sound clip for an input liquid motion is automatically retrieved from the database. The retrieval is achieved by comparing a waveform of the sound and a history of velocity of the liquid motion computed by the simulation. The velocity history is computed for the regions where the liquid sound is expected to occur. Then, a distance between the velocity history and the waveform of each sound clip in the database is calculated, and our system chooses the clip with the minimum distance. Our method achieves fast synthesis of liquid sound for simulated liquid motion, once the database is prepared. In this paper, we use a small database containing a few sound clips and evaluate the effectiveness of our retrieval approach, as a preliminary experiment of this research.","PeriodicalId":199099,"journal":{"name":"SIGGRAPH Asia 2021 Posters","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131668007","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}

In this work, we present a wearable, lightweight and affordable embedded system aiming to provide both tactile and kinesthetic feedback in 3D applications. We created a PCB for the circuitry and used inexpensive components. The kinesthetic feedback is provided to the user’s hand through a 3D-printed exoskeleton and five servo motors placed on the back of the glove. Tactile feedback is provided to the user’s hand through fifteen coin vibration motors, placed in the inner side of the hand and vibrating at three levels.

The graphical rendering limitations prevent state-of-the-art interaction techniques from achieving segmented bare-body user input to manipulate live point cloud data. We propose BridgedReality, a toolkit that enables users to produce localized virtual effects in live scenes, without the need for an HMD nor any wearable devices or virtual controllers. Our method uses body tracking and an illusory rendering technique to achieve large scale, depth-based, real time interaction with multiple light field projection display interfaces. This toolkit circumvented time-consuming 3D object classification, and packaged multiple proximity effects in a format understandable by middle schoolers. Our work can offer a foundation for multidirectional holographic interfaces, GPU simulated interactions, teleconferencing and gaming activities, as well as live cinematic quality exhibitions.","PeriodicalId":199099,"journal":{"name":"SIGGRAPH Asia 2021 Posters","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123548725","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, we experienced an asset management problem in our previous short film production; we needed to manually create many MatCap assets to achieve variations shot by shot or even frame by frame. In this work, we identify requirements for shading systems in Japanese animation production and describe our procedural MatCap system, which satisfies the requirements. Procedural MatCap generates customizable MatCap assets fully procedurally in run time, which drastically improves the asset manageability.","PeriodicalId":199099,"journal":{"name":"SIGGRAPH Asia 2021 Posters","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114359144","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}
