This is a guide to producing and using 3D models of real objects and environments for Wikimedia projects. 3D models are now supported on Wikimedia Commons, derivatives from 3D models including those using photogrammetry are also useful captured as images or videos: to show objects from directions it is not possible to take a photograph.
In computer graphics, it is commonly used to create textures and 3D models. In video games, it is used to automatically create large amounts of content in a game. Depending on the implementation, advantages of procedural generation can include smaller file sizes, larger amounts of content, and randomness for less predictable gameplay.
The two most common sources of 3D models are those that an artist or engineer originates on the computer with some kind of 3D modeling tool, and models scanned into a computer from real-world objects (Polygonal Modeling, Patch Modeling and NURBS Modeling are some popular tools used in 3D modeling). Models can also be produced procedurally or ...
Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and textures from sets of rules that may be easily changed over time. [1] L-Systems , fractals , and generative modeling are procedural modeling techniques since they apply algorithms for producing scenes. [ 2 ]
The prior knowledge is statistically extracted from a database of 3D examples and used as a basis to represent or generate new plausible objects of that class. Its effectiveness lies in the ability to efficiently encode this prior information, enabling the solution of otherwise ill-posed problems (such as single-view 3D object reconstruction).
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 ...

Solid texturing is a process where the texture generating function is evaluated over at each visible surface point of the model so the resulting material properties (like color, shininess or normal) depends only on their 3D position, not their parametrized 2D surface position like in traditional 2D texture mapping. Consequently, solid textures ...
