- Hackathon – A hackathon is an event where teams of developers, designers, and other professionals come together to collaborate on a project, usually over the course of a day or a weekend. The goal is to create a working prototype or solution that solves a specific problem or addresses a particular challenge. Participants often work intensively, often overnight, to brainstorm, develop, and test their ideas. Hackathons can be organized by companies, universities, or other organizations to spur innovation, encourage teamwork and problem-solving, and showcase new technologies or products. Hackathons often have a competitive aspect, with judges evaluating the projects and awarding prizes or recognition to the top teams.
- Low Polygon Count vs High Polygon Count – Low polygon count and high polygon count refer to the number of polygons used to create a 3D model or scene. Low polygon count models use fewer polygons, resulting in simpler shapes and less detail, while high polygon count models use more polygons, resulting in more complex shapes and more detail. Low polygon count models are often used in real-time applications, such as video games, where performance is critical. High polygon count models are typically used in pre-rendered content, such as movies or still images, where visual quality is the primary concern. Finding the right balance between polygon count and performance is important for creating immersive and engaging 3D experiences.
- Mozilla Hubs – Mozilla Hubs is a web-based platform that enables users to create and join virtual rooms where they can interact with others using customizable avatars and voice chat. It uses WebVR technology to allow users to access virtual rooms directly from their web browser.

- Polygon – In computer graphics, a polygon is a flat, two-dimensional shape made up of straight lines or edges that connect to form a closed shape. Polygons are used extensively in 3D modeling and animation to create surfaces, shapes, and objects. The number of edges, or sides, in a polygon can vary, but a polygon must have at least three sides to be considered a polygon. The corners, or vertices, of a polygon are points where two or more edges meet. The shape of a polygon is determined by the position of its vertices in three-dimensional space. Polygonal modeling is a key technique used in 3D graphics, and polygons are a fundamental component of most 3D models.
- Polygon Count – Polygon count, also known as poly count or triangle count, is the number of polygons used to create a 3D model or scene. The higher the polygon count, the more detailed and realistic the model or scene will appear. However, a higher polygon count also requires more processing power and memory, which can impact performance. Polygon count is a crucial consideration in 3D graphics, especially in game development and real-time applications. 3D artists and game developers need to balance polygon count with performance and visual quality to create the most immersive and engaging experiences possible. Reducing polygon count through optimization techniques can improve performance and reduce rendering times while maintaining visual fidelity.
- Room – In the context of WebXR Mozilla Hubs, a room is a virtual environment that users can join to interact with others in real-time using customizable avatars and voice chat. Rooms are created by users or organizations and can be customized with different layouts, objects, and environments to suit the purpose of the room, such as a meeting space, classroom, or social gathering. Rooms in Mozilla Hubs can be accessed directly from a web browser or virtual reality headset, and users can move around and interact with the environment using keyboard and mouse controls or VR hand controllers. Rooms can also include interactive elements such as media, 3D models, and whiteboards to facilitate collaboration and engagement.
- Scene – In computer graphics, a scene refers to a collection of objects, lights, cameras, and other elements that define a virtual environment. A scene can be a static image or an animated sequence, and it can be viewed from various perspectives or angles. Scenes can be created using 3D modeling software or game engines, and they are used in a wide range of applications, from movie and video game production to architectural visualization and product design. Creating a compelling scene involves balancing visual elements such as lighting, textures, and materials, as well as considering the desired mood or atmosphere. Scenes can vary widely in complexity and style, depending on the intended use and audience.

- X, Y and Z Axis – In three-dimensional space, the X, Y, and Z axes are used to define positions and movements of objects. The X axis is the horizontal axis, the Y axis is the vertical axis, and the Z axis is the depth axis. When referring to the orientation of an object, the X axis runs from left to right, the Y axis runs from bottom to top, and the Z axis runs from front to back. Together, these three axes allow for precise location and movement of objects in 3D space. Understanding the X, Y, and Z axes is essential in 3D modeling, animation, and game development.
- WebXR – WebXR is a technology that allows developers to create and deploy immersive and interactive virtual and augmented reality experiences on the web.
