The Confidentiality of Coding Video Games with Cheat Code and Bots for Cheating in a Virtual World

Video games have been around for several decades and have had many advancements from the original start of video games. Video games started as virtual games that were advertised towards children, and these virtual games created a virtual reality of a variety of genres. These genres included sports games, such as tennis, football, baseball, war games, fantasy, puzzles, etc. The start of these games was derived from a sports genre and now has a popularity in multiplayer-online-shooting games. The purpose of this paper is to investigate different types of tools available for cheating in virtual world making players have undue advantage over other players in a competition. With the advancement in technology, these video games have become more expanded in the development aspects of gaming. Video game developers have created long lines of codes to create a new look of video games. As video games have progressed, the coding, bugs, bots, and errors of video games have changed throughout the years. The coding of video games has branched out from the original video games, which have given many benefits to this virtual world, while simultaneously creating more problems such as bots. Analysis of tools available for cheating in a game has disadvantaged normal gamer in a fair contest.

Precise conversion between virtual world and real world in stereoscopic imaging

A method for precise conversion between virtual world and real world is put forward in this paper. The method aims to precisely establish the connection between the virtual coordinates and the real coordinates with OpenGL. In the virtual world, two virtual cameras are set to capture the left and right perspective planar images, and coordinates of the planar images can be calculated by the perspective projection model. With coordinates of planar images, coordinates of the stereo- scopic image synthesized in the real world can be calculated by the binocular observation model. Therefore, the corresponding connection between the two systems is established. Experimental re- suits match data from this method well. Therefore, this method can precisely realize the conversion and the interactivity, laying a solid foundation for further study.

Analyzing Virtual World Region Fidelity on Scalability and Simulation Performance

Virtual world simulation offers tremendous potential opportunities to improve, and optimize, individual and collective echelon training for the military. The US Army Research Laboratory (ARL) Military Open Simulator Enterprise Strategy (MOSES) project’s charter is to investigate simulation-based training technology for use in military specific training domains. Of particular interest are attributes of virtual worlds such as geographically distributed large-scale trainee support. We have initiated a series of experiments to determine appropriate benchmarks for simulator performance and to determine appropriate independent variables in order to create a robust predictive model that will enable virtual world training scenario designers to calculate, a priori, the number of trainees that may synchronously operate in a virtual world. The present paper’s purposes were to determine the effect that virtual world region fidelity had on server performance and determine whether this independent variable would be appropriate for inclusion into our predictive model. We found that region fidelity had a statistically significant effect on the simulator’s processor memory usage but had no significant effect on the simulator’s vertical scalability, CPU usage nor network performance. In this paper, we discourse on the purpose of this research, our experimental methodology and results, and discuss the significance of our findings.

The World Ophthalmology Congress 2020 is going virtual

Dear Colleagues,The International Council of Ophthalmology (ICO) is deeply committed to the health and safety of our communities during the COVID-19 pandemic.Unfortunately,due to escalating risks,a physical meeting of our international colleagues and partners at the World Ophthalmology Congress (WOC2020) in Cape Town 26-29 June,is no longer possible.While we are all disappointed that our face-to-face meeting is cancelled,the ICO remains devoted to bringing together the world’s ophthalmologists to learn the latest from one another,and to advance eye care during these extraordinarily challenging times.

DTN中基于虚拟货币交易的高效率路由算法

由于容迟网络的间歇性连接等特点,以及节点自身缓存、能量等资源受限,DTN中的节点往往会表现出一定的自私性。自私节点的存在可能会提高网络的开销,降低消息的成功投递率。为了促进自私节点参与合作,提出了一种基于虚拟货币交易的高效率路由算法PVCT(Efficient Routing Algorithm Based on Virtual Currency Transaction in DTN),并结合容迟网络的小世界特性,提高了路由算法的效率。该算法利用虚拟货币交易的方式,并根据节点的基本属性、位置属性、社会属性等进行定价,节点根据设计的价格函数给出对应的报价,并利用价格函数合理地分配消息副本数。在PVCT策略中,节点根据判断情况分为正常节点和自私节点,当消息的跳数小于或等于两跳时,按照概率路由的策略进行转发;反之,当消息的跳数大于两跳时,若遇到的为自私节点,则执行虚拟货币交易的路由算法。携带消息节点的出价若高于转发节点的价格,则进行交易,更新各自的收益状态;否则,进入二次价格调整阶段以协调节点双方之前的虚拟报价。仿真实验表明,PVCT路由算法在DTN中能更好地促进消息的转发,从而提升网络的整体性能。

元宇宙金融的跨界融合治理——以多元货币融合为重点

自元宇宙行业兴起以来,金融机构开始在虚拟世界提供新型金融服务,而私人加密货币和去中心化金融市场也在虚实世界的融合中得以优化发展。元宇宙金融的本质是用户享有高度自主性的虚实跨界融合,包括现实虚构、虚为实用、虚替实用,其重点在于多元货币的融合。我国将正规金融机构既有业务的“元宇宙化”与私人加密货币进行区分式治理的策略,难以应对元宇宙金融在金融工具、主体、行为等方面存在的风险挑战。对此,应在智慧规制理论的基础上、结合不同跨界融合场景对现实世界的影响程度而采用“跨界融合治理”模式。具体而言,应通过货币持有、货币流通、债务清偿三行为实现私人加密货币与法定数字货币的法律地位协调,按照前端、中端、后端三阶段构建“双重金融消费者”的适当性制度,并在市场准入、行为标准、风险防控方面确立跨界货币运营机构的准公共职能。

元宇宙诉讼的认知、障碍和建构逻辑

我国现阶段诉讼数智化发展面临着诉讼平台破碎化和数据壁垒化的双重困境,元宇宙技术的体系化和虚拟化特征高度迎合我国打造全系统一体化、全时空泛在化的人民法院信息化4.0版的司法改革需求,通过整合现有数字化技术群,元宇宙诉讼能对现有的数字化司法资源进行再分配,是突破现阶段民事智能司法发展瓶颈和内卷现状的重要契机。在看到元宇宙巨大的潜在诉讼利用价值的同时也需警惕技术至上主义,未来元宇宙诉讼的构建在技术开发上应以司法人员为主导,在设计理念上秉承以人为本的指导思想,应划清人机协同的分工界限,并明确智能司法决策的责任主体以强化对技术的法律约束。

Learning layout generation for virtual worlds

The emergence of the metaverse has ledto the rapidly increasing demand for the generation ofextensive 3D worlds. We consider that an engagingworld is built upon a rational layout of multiple landuse areas (e.g., forest, meadow, and farmland). Tothis end, we propose a generative model of landuse distribution that learns from geographic data.The model is based on a transformer architecturethat generates a 2D map of the land-use layout,which can be conditioned on spatial and semanticcontrols, depending on whether either one or bothare provided. This model enables diverse layoutgeneration with user control and layout expansion byextending borders with partial inputs. To generatehigh-quality and satisfactory layouts, we devise ageometric objective function that supervises the modelto perceive layout shapes and regularize generationsusing geometric priors. Additionally, we devise aplanning objective function that supervises the modelto perceive progressive composition demands andsuppress generations deviating from controls. Toevaluate the spatial distribution of the generations, wetrain an autoencoder to embed land-use layouts intovectors to enable comparison between the real andgenerated data using the Wasserstein metric, which isinspired by the Fr´echet inception distance.

虚拟空间的自我建构:卡夫卡的“变形”美学

随着现代信息技术的发展,网络平台应用得到普及,深刻影响了个体主观性的操作和调控,从而造就了一批新时代的“变形人”。本文运用文本细读法和归纳总结法,重读弗兰茨·卡夫卡的经典小说《变形记》,探讨卡夫卡的“变形人”在现实人生和虚拟世界交互关系中的生存策略,阐释卡夫卡的变形美学对当代网络空间自我虚拟人格建构的重要思想启示。卡夫卡把现实世界中人类反抗异化的行动融入有限生命的无穷精神诉求中,虚拟世界中个体的自我建构在一定程度上缓解了现代人的生存困境与精神危机。如今的人们面临更为复杂多元的生活形态,加上自我建构中诸多社会性和个体性因素的影响,“变形”已然成为普遍的生存状态和抗争模式。人类在现实与虚拟、自由与枷锁之间找寻着在世界中的和谐状态。

虚拟世界“涌现”下数字财产交易的双层法律关系解构

数字财产属于物权客体、债权客体、知识产权客体、新型权利客体的争论均局限于数字财产“去中心化”的特征,忽略了数字财产“去人化”的本质。虚拟世界系一独立的世界,而并非现实世界的附属空间,数字财产为虚拟世界的“物”;数字财产的财产所有人并非账号持有人,而是账号系统本身。数字财产交易是跨越“虚拟世界”和“现实世界”的交易,这一交易存在四方交易主体。在数字财产交易过程中,如果不可替代的标的属于现实的财产或服务,则其本质属于现实世界的交易,应当根据现实标的计算交易价值;如果不可替代的标的属于数字财产,则其本质属于虚拟世界的交易,应根据数字财产计算交易价值。
