3Dsisältö

3Dsisältö is a Finnish term used to describe three-dimensional digital content. The term combines 3D and sisältö (content) and is used in Finnish media, education, design, and industry to refer to assets and media created in three dimensions for visualization, interaction, or simulation. 3Dsisältö encompasses assets such as 3D models, textures, materials, lighting, rigging, animation data, and entire scenes, as well as real-time assets used in games, virtual reality, augmented reality, simulations, and architectural visualization.

Types and formats: The main components include 3D models (polygonal meshes, NURBS), textures and materials, lighting setups, rigging and animation data, and scene graphs. 3D content is stored and exchanged in formats such as glTF, USD, OBJ, FBX, COLLADA (DAE), STL, and native project formats of software packages.

Creation and workflows: 3Dsisältö is produced with software tools such as Blender, Autodesk Maya, 3ds Max, Cinema 4D, and ZBrush; photogrammetry may generate models from real-world objects. Real-time content is often developed in game engines like Unity and Unreal, while pipelines may involve CAD/BIM for architecture or product design.

Delivery and use: 3D content is delivered for web via WebGL and WebXR, used in VR/AR headsets, mobile apps, and desktop applications. It is widely used in entertainment, marketing, product visualization, architecture, education, and research. Key considerations include performance optimization, level of detail, accessibility of 3D content, licensing, and interoperability through open standards.
