A 2D image will not provide as complete a representation of an object as a 3D model. That is why three-dimensional modeling is effectively and successfully used in production and in advertising. Three-dimensional modeling can be used for a more effective representation of the battlefield, taking into account the relief of real terrain, and 3D modeling is also successfully used in design projects when creating various models. And they apply for such work on the island in proven services, such as 3d visualization services by 3Nitro.
The use of simulation allows optimization of various technological processes. Three-dimensional modeling can easily replace natural prototyping, for example, it will allow you to create a 3D model of a node communication or element of the communication system.
3D modeling gives you access to a fast process design, engineering analysis, and preparation of production of products of any purpose and complexity.
A three-dimensional image on a plane, in contrast to a two-dimensional one, includes the construction of a geometric projection of a volumetric model onto a plane using specialized programs. 3D graphics active are used in television, cinema, printed materials, computer games, science, industry, design automation systems (CAD), in architectural and medical visualization.
The main functions and capabilities of 3D programs:
-simulation of three-dimensional graphics;
-creation of a three-dimensional model of the scene and 3D objects in it;
-rendering (visualization);
-building a projection of the model;
-processing and editing images;
– output of the received image to the output device – printer, display.
3D graphics – a type of computer graphics, visual display of a three-dimensional scene or object on the screen of a monitor or some other device. The 3D imaging process can be divided into three sequential stages. At the first stage, the object is transformed into a model divided into many polygons (polygons). The next step involves geometric transformations with polygons and lighting settings. The final stage is rendering, in which a two-dimensional image is created from the polygons obtained in the previous stages. The final image is obtained from rendering (rendering) a pre-modeled 3D scene.
Typically, each scene is a collection of the following elements:
-a set of different objects with different properties;
-a set of light sources;
-set of textures for objects;
– at least one camera or several cameras.
Each scene in 3D graphics consists of objects. Each object can consist of:
– tops;
– a set of edges (edge – 2 vertices forming a straight line);
– a set of polygons (polygon – at least 3 vertices forming a plane.
Typically, a polygon consists of 3 or 4 vertices, but in some 3D modeling programs polygons can consist of more vertices).
An object can have different properties and behavior (properties of its material – for example, such as transparency, specularity, texture reflection features, etc.); the behavior of an object is determined by its location in space (displacement, rotation axis, rotation angle, scaling factor, etc.)
Each light source in the scene is set with the following parameters:
– the position of the light source in space;
-orientation (the point to which this source is directed);
-type (background / directional / non-directional);
– color scheme (usually RGB).
All 3D graphics editors have their own set of light sources and various features for managing them.
Textures in the scene represent a two-dimensional image of various formats, which is projected onto a three-dimensional model.
The camera in a three-dimensional scene is used to determine the area of the scene needed for rendering.
Each camera is set with the following basic parameters:
-position in space;
-direction (more precisely, the point to which this camera is directed);
-vision angle;
