WHAT IS POLYGONAL MODELING

There are several types of 3D modeling: wireframe, solid, surface, generative and polygonal. A volumetric visualization using polygons is the very first version 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 polygonal modeling?

Polygonal modeling – low-level modeling, which allows you to visualize an object using a polygon mesh.

Polygonal meshes consist of such subobjects:

The vertex is the junction point of the edges, there can be as many as desired;

Edges – lines that protrude by the boundaries of faces;

Faces or polygons – grid cells, sections 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 subobjects. 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 IMPLEMENTED 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, there is no need to do any additional parameters and calculations. However, this method requires patience and perseverance, because to create even the most simple 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.

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 (for example, a cube or a cylinder) are taken as a basis, then the desired model is constructed by drawing subobjects, dividing existing faces.

Drawing new faces from the source polygon, when each subobject appears from the previous one.

Manually, without source and primitives, when all subobjects are drawn, rather than stretched.

Polygonal modeling provides three basic methods for constructing visualization objects.

Simulation with vertices – manipulations with vertices, their movement, removal, etc. are carried out.

Modeling with the help of edges – 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 FOR THE CREATION OF POLYGONAL 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, building 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 precise 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.
