    Automated Generation of Map Pieces for Snappable Meshes
    (ACM, 2023-04-12) Andrade, Diogo de; Fachada, Nuno
    Snappable Meshes is an algorithm that procedurally generates 3D environments by iteratively selecting and linking pre-built map pieces. These pieces are triangular meshes annotated by designers with connectors marking potential links, and bounding volumes indicating where overlaps should be avoided. In this article, we present a method for automatically generating connectors and bounding volumes from generic non-manifold triangular meshes for use with the Snappable Meshes algorithm, minimizing artist/designer work, while encouraging iteration of map piece design, an essential part of successful environment generation.

    Fun Maths for All Game Development Students
    (ACM, 2020-06) Andrade, Diogo de; Fachada, Nuno; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    We present an approach for teaching maths to game development undergraduates from a wide variety of backgrounds. We discuss the concepts behind an introductory maths course, its assessment and put forward some preliminary results on a practical implementation.

    Procedural game level generation by joining geometry with hand-placed connectors
    (SPCV, 2020) Silva, Rafael Castro e; Fachada, Nuno; Códices, Nélio; Andrade, Diogo de; Faculdade de Engenharia
    We present a method for procedural generation of 3D levels based on a system of connectors with pins and human-made pieces of geometry. The method avoids size limitations and layout constraints, while offering the level designer a high degree of control over the generated maps. The proposed approach was originally developed for and tested on a multiplayer shooter game, nonetheless being sufficiently general to be useful for other types of game, as demonstrated by a number of additional experiments. The method can be used as both a level design and level creation tool, opening the door for quality map creation in a fraction of the time of a fully human-based approach.

    Procedural generation of 3D maps with snappable meshes
    (IEEE, 2022-04-20) Silva, Rafael Castro e; Fachada, Nuno; Andrade, Diogo de; Códices, Nélio; Faculdade de Engenharia
    In this paper we present a technique for procedurally generating 3D maps using a set of premade meshes which snap together based on designer-specified visual constraints. The proposed approach avoids size and layout limitations, offering the designer control over the look and feel of the generated maps, as well as immediate feedback on a given map’s navigability. A prototype implementation of the method, developed in the Unity game engine, is discussed, and a number of case studies are analyzed. These include a multiplayer game where the method was used, together with a number of illustrative examples which highlight various parameterizations and piece selection methods. The technique can be used as a designer-centric map composition method and/or as a prototyping system in 3D level design, opening the door for quality map and level creation in a fraction of the time of a fully human-based approach. INDEX TERMS : 3D maps, computer games, designer-centric methods, layout, procedural content generation (PCG).

    PyXYZ: an educational 3D wireframe engine in Python
    (ACM, 2021-06-26) Andrade, Diogo de; Fachada, Nuno; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    In this paper we introduce PyXYZ, a 3D wireframe software rendering framework for educational purposes. The main goal of this framework is to provide a simple-to-understand tool that students can use to build a more sophisticated engine, while learning mathematics and acquiring a deeper knowledge of the complexity of a modern 3D engine. PyXYZ can be used as a teaching aid in course work and/or as a template for multi-goal project assignments, allowing students with diverse capabilities and interests to have different levels of commitment. The engine has been used with positive results in a mathematics course unit of a computer games BA and can be easily adapted to various teaching scenarios.

    Unity Snappable Meshes
    (Elsevier B.V., 2022-08-01) Fachada, Nuno; Silva, Rafael Castro e; Andrade, Diogo de; Códices, Nélio; Faculdade de Engenharia
    The Snappable Meshes algorithm procedurally generates 3D maps for computer games by iteratively selecting and linking pre-built map pieces via designer-specified connectors. In this paper we present an implementation of this algorithm in the Unity game engine, describing its architecture and discussing core implementational solutions. A number of examples illustrate the potential of the algorithm and the capabilities of the software. We assess the application’s impact on past and ongoing research, and how it can be improved to support future research questions.
