3d Polygonal Modeling Services

3d polygonal modeling services. There are several types of 3D modeling: wireframe, solid, surface, generative and polygonal. A volumetric visualization using polygons is the very first kind of 3D modeling. Polygonal modeling 3d max has its own nuances and complexities, but this method is still very popular in the field of 3D-technologies.

What is 3d polygonal modeling?

Polygonal modeling is a low level simulation that allows you to visualize an object using a polygon mesh.
Polygonal meshes consist of such sub objects:
The vertex is the junction point of the edges, there can be as many as desired;
Edges – lines that act as boundaries of faces;

Faces or polygons – grid cells, areas of the plane, which are most often triangular or quadrangular. A polygonal mesh can consist of a huge number of identical cells.

To create a 3D model of an object, you must work with sub objects. You can change their scale and shape, rotate, merge and divide, as well as apply other operations that allow special computer programs.

Polygonal Modeling Is Performed In Such Programs:

3ds Max;
Maya;
Alias;
Rhino.

Polygonal meshes are a collection of polygons, from which contours are formed, the shell of the future object. It seems that they are easy to work with; they have clearly defined external and internal area, no need to make any additional parameters and calculations. However, this method requires patience and perseverance, because to create even the simplest three dimensional model, you need to make thousands of mouse clicks. The smallest mistake can reduce all the work is not “no”, since it is very difficult to remake the finished object.

Methods and Methods for Constructing Polygonal Models

There are three basic techniques for creating polygonal models, which are most often used in a combined version, but can also be used, in pure form.

With the help of primitives – when the finished geometric figures are taken (for example, a cube or a cylinder), then the desired model is constructed by drawing sub objects, dividing existing faces.

Drawing new faces from the source polygon, when each sub object appears from the previous one. Manually, without source and primitives, when all sub objects are drawn, rather than stretched. Polygonal modeling provides three basic methods for constructing visualization objects.

Modeling with the help of vertices – manipulations with vertices, their movement, removal, etc. are carried out. Modeling with the help of ribs – to give the desired shape to the object, the position of the edges, their dimensions, changes. Modeling by means of polygons – faces are used for more complex operations, for example, giving shapes to convexity or vice versa, smoothing or indenting the surface, here work is carried out with planes.

Recommendations when Creating Polygon Models

It is better to use quadrangular geometric shapes. They are easier to deform, which allows you not to waste time on unnecessary manipulation. It is recommended to use as few triangles as possible.

Do not use complex geometric shapes, with lots of corners and edges, this can lead to deformation of the texture?

When creating a polygon model, you only need to visualize the necessary elements, constructing additional structures complicates the model itself, if it’s small details, you can do them using textures.

Polygonal modeling is designed primarily to create volumetric models of objects with exact shapes and clear contours. Objects are composed of polygons – tiny faces that have a shape and color. This method today is most often used in industrial design.
