3Dscène

3Dscène is a term used in computer graphics and visualization to denote a three-dimensional scene. It refers to the virtual space in which objects, light sources, cameras, and environmental effects are defined and rendered from a chosen viewpoint.

A 3Dscène comprises multiple elements: 3D models with geometry and topology; materials and textures; lighting setups; a camera or multiple cameras; and environmental parameters such as fog, atmosphere, and physical properties. These elements are organized in a scene graph or another hierarchical structure that governs spatial relations and animation through transforms.

Scenes are described and exchanged through data representations and APIs. Common interchange formats and APIs provide structures for meshes, materials, lights, cameras, animation channels, and physics properties. Real-time engines may optimize a 3Dscène with frustum culling, level of detail, and instancing to maintain performance.

Rendering pipelines convert a 3Dscène into a 2D image. Depending on the application, this may involve rasterization, ray tracing, or hybrid methods, along with shading models, shadows, reflections, and post-processing effects.

Applications of 3Dscène include film and television production, architectural visualization, product design, video games, virtual reality, and simulation. Software tools for constructing and rendering 3Dscènes range from general 3D modeling packages to game engines and specialized visualization systems.

Etymology and usage: the word scènes meaning "stages" or "scenes" in French underpins the term 3Dscène. In French-language documentation, 3Dscène is often used as a label for the concept of a managed 3D scene.
