We have tested this approach over two semesters in an introductory level graduate rendering & shading class at Texas A&M University. The students in the class each chose an artist's style to mimic, and then easily created rendered images strongly resembling that style (see Figures 1). The method provides shader developers an intuitive process, giving them a high level of visual control in the creation of stylized depictions.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128179133","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}

{"title":"Increasing realism of animated grass in real-time game environments","authors":"Benjamin Knowles, O. Fryazinov","doi":"10.1145/2787626.2787660","DOIUrl":"https://doi.org/10.1145/2787626.2787660","url":null,"abstract":"With the increasing quality of real-time graphics it is vital to make sure assets move in a convincing manner otherwise the players immersion can be broken. Grass is an important area as it can move substantially and often takes up a large portion of screen space in games. Animation of grass is a subject to academic research [Fernando 2004; Perbet and Cani 2001] as well as a technology which is implemented in a number of video games. The list includes, but is not limited to, games such as Far Cry 4, Battlefield 4, Dear Esther and Unigine Valley. Comparing video games assets with reality, it can be seen that the current methods have a number of problems which decrease the realism of the resulting grass animation. These problems include: 1) the visible planar nature of grass geometry and 2) problems with the grass movement which include over-connectivity of grass blades in respect to their neighbours, no obvious wind direction and exaggerated swaying motions. In this paper we propose to increase realism of the grass by focusing on its movement. The main contributions of this work are: 1) Distinguishing ambient and directional components of the wind and 2) The method for calculating directional wind by using a grayscale map and wind vector. The grass was implemented with vertex shaders in line with the majority of methods described in academic literature (e.g. [Fernando 2004]) and implemented in modern games.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274530","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}

Several hollow needles are percutaneously inserted in the target area under image guidance and a gas (usually argon) is then decompressed inside the needles. Based on the Thompson-Joule principle, the temperature drops drown and a ball of ice crystals forms around the tip of each needle. Radiologists rely on the geometry of this iceball (273 K), visible on computer tomographic (CT) or magnetic resonance (MR) images, to assess the status of the ablation. However, cellular death only occurs when the temperature falls below 233 K. The complexity of the procedure therefore resides in planning the optimal number, position and orientation of the needles required to treat the tumor, while avoiding any damage to the surrounding healthy tissues.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114699358","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}

Color as such is a compelling cue to elicit emotional responses and thus can enhance the emotional quality of an image. Tools and methods have been developed to automatize the color selection process, and a noticeable progress has been achieved to extract perceptually dominant colors of an image. However, little attention has been paid to the emotional characteristics of selected colors, and it has been highly relying on the color designers' manual judgments. In this study, we propose a computational method that creates a color that enhances both aesthetic and affective quality of an image, and call it a theme color.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131026776","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}

When used for treatment planning these segmentations need to not only be accurate but also produced quickly to avoid health risks. Automatic segmentation methods are becoming more reliable but many experts in the scientific community still rely on time consuming manual segmentation.","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131256121","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, there has been little research on generating illustrations of trees [Yu-Sheng et al. 2012]. One of the ways to generate them is to render their 3D models. However, it is difficult to obtain the characteristic flat representation of illustrations because of the concentration of foliage in the central part of the tree. We present a system to generate a wide variety of tree illustrations by controlling the density of branches, the shape of canopy, and the overlap of flowers and leaves (Fig. 1).","PeriodicalId":269034,"journal":{"name":"ACM SIGGRAPH 2015 Posters","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132012337","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}
