    Get PDF
    Simulating realism has become a standard for many games in the industry. While real-time rendering requires considerable rendering resources, texturing defines the physical parameters of the surfaces with a lower computer power. The objective of this thesis was to study the evolution of Texture Mapping and define a workflow for approaching a photorealism with modern instruments for video game production. All the textures were created with the usage of Agisoft Photoscan, Substance Designer & Paintrer, Abode Photoshop and Pixologic Zbrush. With the aid of both the theory and practical approaches, this thesis explores the questions of how the textures are used and which applications can help to build them for a better result. Each workflow is introduced with the main points of their purposes as the author’s suggestion, which can be used as a guideline for many companies, including Ringtail Studios OÜ. In conclusion, the thesis summarizes the outcome of the textures and their workflow. The results are successfully established by the author with attendance to introduce methods for the material production

    Thesis (S.B. in Art and Design)--Massachusetts Institute of Technology, Dept. of Architecture, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 29).The entertainment industry relies fairly heavily on computer-generated imagery to depict built environments in current films, video games, and other forms of simulated reality. These often involve highly complex geometries that take a long time to hand-model and are too difficult or costly for many productions' rendering capacities, both in computational costs as well as time. Procedural modeling and the automation of these geometries is one option to solve these problems. Many modeling programs involve a script or procedural modeling component. This thesis explores the use of CityEngine, a commercially available software that is specialized to generate geometries for buildings in urban environments. By using the CGA Shape Grammar built into CityEngine, this project seeks to generate geometries based on complex architectural precedents using a procedural modeling system based on shape grammar and computational design principles. Results are generated and discussed, as well as applications and future work.by Anisha V. Deshmane.S.B.in Art and Desig

    Hráči počítačových her mají stále vyšší a vyšší nároky na grafické zpracování herního světa a jeho detaily. Aby jim mohlo být vyhověno, grafici musí neustále upravovat svůj přístup a používané modelovací techniky. Jeden z moderních a populárních přístupů je založen na modularitě a modulárním designu. Přestože tento přístup má spoustu benefitů, přesný popis technik a znalostí spojených s tímto konceptem není stále pevně definovaný. Tato práce poskytuje náhled na různé modelovací techniky, software pro 3D modelování a detailní popis modulárního přístupu aplikovaného v aktuálních počítačových hrách. Kombinací procedurálních modelovacích technik a modulárního designu jsme v programu Houdini připravili několik assetů už pouze čekajících na reálné využití. Dále jsme v Unreal Enginu poskládali testovací scénu a tím získali hlubší přehled o výhodách a nevýhodách použitého přístupu k tvorbě grafiky počítačových her.In order to keep up with the ever-increasing player's demand for higher visual fidelity of game environments, artists are continually implementing new modelling techniques and production methods into their workflow. One popular contemporary approach that has emerged is based on the notion of modular design. Although it offers many benefits for production workflow, the particular techniques and skills associated with this concept are still not well defined. This thesis provides an overview of various modelling techniques, 3D modelling software and thorough discussion of the modular design paradigm applied in computer games. We have combined procedural modelling techniques with the concept of modular design to create several game-ready assets in Houdini. We then assembled a simple test scene in Unreal Engine in order to gain a more in-depth insight into the advantages and disadvantages of the discussed workflow

    The following thesis details the creation of a shot for an animated production titled Gear Up. The process for creating this shot was patterned after professional animated productions and included the following steps: pre-visualization, story boarding, modeling and asset creation, UV layouts, texturing and surfacing, scene assembly and camera layout, character and prop rigging, character animation, lighting, rendering, and compositing. The motivation for this project was to create a product that artistically has a darker aesthetic than many previous Clemson DPA animations, but still enjoyed high quality visuals. One of the goals was to create a large-scale scene centered in a post apocalyptic robot war. This project also served as the first opportunity for incorporating the rendering engine called Arnold into the Clemson DPA animation pipeline and artist workflow. In order to accomplish the goals set above, a series of technical and artistic problems needed to be solved. With the use of 3D preproduction prototyping, modular and procedural asset gen-eration, new content generation tools, and optimized workflows, the team was able to tackle all production challenges and create high quality content efficiently and with minimal stress to the artists. This thesis also delves into the elaborate process of scene lighting; detailing the artistic decisions and motivations that lead to the final product. The lighting is created by examining references from film and real life, lighting designs, and advanced lighting techniques. The results of the project was a 400 frame animation of a post apocalyptic city block featuring a detailed robot, armed for war, standing guard by his tank amidst piles of debris, barbed wire, and rubble. The shot was rendered entirely in Arnold apart from the FX elements, which was rendered using Houdini Mantra. It also represents a successful collaboration between several volunteer artists with various skills and time commitments

    Procedural digital twin generation for co-creating in VR focusing on vegetation

    Get PDF
    An early-stage development of a Digital Twin (DT) in Virtual Reality (VR) is presented, aiming for civic engagement in a new urban development located in an area that is a forest today. The area is presently used for recreation. For the developer, it is important both to communicate how the new development will affect the forest and allow for feedback from the citizen. High quality DT models are time-consuming to generate, especially for VR. Current model generation methods require the model developer to manually design the virtual environment. Furthermore, they are not scalable when multiple scenarios are required as a project progresses. This study aimed to create an automated, procedural workflow to generate DT models and visualize large-scale data in VR with a focus on existing green structures as a basis for participatory approaches. Two versions of the VR prototype were developed in close cooperation with the urban developer and evaluated in two user tests. A procedural workflow was developed for generating DT models and integrated into the VR application. For the green structures, efforts focused on the vegetation, such as realistic representation and placement of different types of trees and bushes. Only navigation functions were enabled in the first user test with practitioners (9 participants). Interactive functions were enabled in the second user test with pupils (age 15, 9 participants). In both tests, the researchers observed the participants and carried out short reflective interviews. The user test evaluation focussed on the perception of the vegetation, general perception of the VR environment, interaction, and navigation. The results show that the workflow is effective, and the users appreciate green structure representations in VR environments in both user tests. Based on the workflow, similar scenes can be created for any location in Sweden. Future development needs to concentrate on the refinement of buildings and information content. A challenge will be balancing the level of detail for communication with residents

    Shedding light on GIS: A 3D immersive approach to urban lightscape integration into GIS

    Get PDF
    Geographic Information Systems (GIS) have the ability to map, model, and analyze real world data and phenomena, and yet visibility and lighting conditions are rarely considered or researched in Geographic Information Science (GISci). Lighting technologies have been created and implemented to overcome the darkness of night and other issues of visibility, and in no place is that more evident than urban areas. Though not researched heavily in GIS, it is now possible to model and analyze lighting of the built environment using GIS, 3D modeling and rendering software. This thesis explores the night time urban lightscape, its spatial aspects and contribution to place as well as its incorporation into GIS and GISci. To capture lighting and its multi-dimensional properties, a 3D model was created of the built environment of Morgantown, WV, USA, including the West Virginia University (WVU) campuses and their exterior lighting. The model was completed through the coupling of ESRI\u27s CityEngine and E-on software\u27s LumenRT4 Geodesign plug-in. Lighting data was obtained through the WVU Department of Construction and Design in the form of a CAD map. After geo-referencing CAD-based exterior lighting data, a raster lighting analysis of WVU\u27s Evansdale Campus was produced to identify under-lit areas. These areas were then redesigned using a lighting design tool and incorporated 3D modeling, GIS, and procedural rule-based modeling. An original workflow was designed consisting of ArcGIS, SketchUp, CityEngine, and LumenRT 4 Geodesign. Lighting scenarios were subsequently viewed and experienced through immersive technologies

    Semi-Automated SVG Programming via Direct Manipulation

    Direct manipulation interfaces provide intuitive and interactive features to a broad range of users, but they often exhibit two limitations: the built-in features cannot possibly cover all use cases, and the internal representation of the content is not readily exposed. We believe that if direct manipulation interfaces were to (a) use general-purpose programs as the representation format, and (b) expose those programs to the user, then experts could customize these systems in powerful new ways and non-experts could enjoy some of the benefits of programmable systems. In recent work, we presented a prototype SVG editor called Sketch-n-Sketch that offered a step towards this vision. In that system, the user wrote a program in a general-purpose lambda-calculus to generate a graphic design and could then directly manipulate the output to indirectly change design parameters (i.e. constant literals) in the program in real-time during the manipulation. Unfortunately, the burden of programming the desired relationships rested entirely on the user. In this paper, we design and implement new features for Sketch-n-Sketch that assist in the programming process itself. Like typical direct manipulation systems, our extended Sketch-n-Sketch now provides GUI-based tools for drawing shapes, relating shapes to each other, and grouping shapes together. Unlike typical systems, however, each tool carries out the user's intention by transforming their general-purpose program. This novel, semi-automated programming workflow allows the user to rapidly create high-level, reusable abstractions in the program while at the same time retaining direct manipulation capabilities. In future work, our approach may be extended with more graphic design features or realized for other application domains.Comment: In 29th ACM User Interface Software and Technology Symposium (UIST 2016

    Virtual integration platform for computational fluid dynamics

    Computational Fluid Dynamics (CFD) tools used in shipbuilding industry involve multiple disciplines, such as resistance, manoeuvring, and cavitation. Traditionally, the analysis was performed separately and sequentially in each discipline, which often resulted in conflict and inconsistency of hydrodynamic prediction. In an effort to solve such problems for future CFD computations, a Virtual Integration Platform (VIP) has been developed in the University of Strathclyde within two EU FP6 projects - VIRTUE and SAFEDOR1. The VIP provides a holistic collaborative environment for designers with features such as Project/Process Management, Distributed Tools Integration, Global Optimisation, Version Management, and Knowledge Management. These features enhance collaboration among customers, ship design companies, shipyards, and consultancies not least because they bring together the best expertise and resources around the world. The platform has been tested in seven European ship design companies including consultancies. Its main functionalities along with advances are presented in this paper with two industrial applications

    An Appetite for the Tasteless: An Evaluation of Off-Color Humor in Adult Animations and Video Games, Presented Through a Proposed Interactive Narrative via a Procedurally Generated Material Library

    Get PDF
    Off-color humor has propelled adult animation into its Golden Age. The success of this genre has prompted media studios to begin developing original series for subscription video-on-demand services. The technology used for these over the top (OTT) streaming services have improved to the point that providers have begun developing cloud-based gaming. These improvements, along with developments in rendering systems, have made it possible to create interactive media across both video and gaming platforms using similar assets. This document will detail the successes of adult animation and the proposal for more interactive narrative media within this category. Accompanying the text will be a procedural material library fitting within the theme and style of adult animation. In recent years media studios have been adapting to tools for a fully procedural texture creation workflow. The focus will be on the creation and implementation of a base material library, as well as examine the benefits and capabilities of said materials across multiple entertainment industries
