Forest scene from Big Buck Bunny, showing light rays through the canopy. Volumetric lighting requires two components: a light space shadow map , and a depth buffer . Starting at the near clip plane of the camera, the whole scene is traced and sampling values are accumulated into the input buffer.

In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. [1] If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction. [2]
Small scripts or programs for generating complex 3D shapes or scenes procedurally; Description of how object and camera locations and other information change over time, for rendering an animation; Many file formats exist for storing individual 3D objects or "models". These can be imported into a larger scene, or loaded on-demand by rendering ...
Basically, a 3D model is formed from points called vertices that define the shape and form polygons. A polygon is an area formed from at least three vertices (a triangle). A polygon of n points is an n-gon. [10] The overall integrity of the model and its suitability to use in animation depend on the structure of the polygons.
It's is the one responsible for the transformation of the prepared 3D scene into a 2D image or animation. 3D render engines can be based on different methods, such as ray-tracing, rasterization, path-tracing, also depending on the speed and the outcome expected, it comes in different types – real-time and non real-time, which was described above

The 3D model can be physically created using 3D printing devices that form 2D layers of the model with three-dimensional material, one layer at a time. Without a 3D model, a 3D print is not possible. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling ...
