This presentation describes 3d modeling and its types and methods.

1. 3D MODELING - TYPES AND
METHODS OF APPLICATION

2. 3D MODELING. MAIN PURPOSE
• Even if you are not working in the 3D modeling industry, you need to
understand the types of 3D modeling. The reason is simple - you
want the ordered images to look as good as possible, so you need to
know which type is best for your projects.
• Here are just a few of the many uses of CGI (computer-generated
imagery, computer-generated images) that require certain types of
3D modeling.
• To familiarize yourself with many of the terms that will be mentioned
later, read the brief list of 3D modeling terms - this way you will not
only learn something new but also greatly simplify communication

3. 3D MODELING IN ADVERTISING AND
PROMOTION
• This is the most common and easy way to use 3D models. If the
marketing department needs images for catalogs or any other
promotional materials, this is where they need a 3D visualization of the
product.
• These images, despite the fact that they are mostly infallible (since
there are only a few rules that a 3D modeler must follow), take a long
time to become great. Of all the types of 3D modeling, there are several
that are used for this sphere.
• Depending on the expected quality of 3D models, you can use polygon
modeling, spline (NURBS) or 3D modeling. The first one is faster and
cheaper, but its level of detail is limited by the number of polygons
(more polygons — smaller details).
• NURBS is simpler than polygonal modeling, but it is limited in terms of
the types of things that can be created with it, specializes in basic

EXAMPLE

5. SIMULATION FOR VR AND AR
• Thanks to VR (virtual reality) and AR (augmented reality) technologies that
revolutionize marketing, there is a high demand for the production of 3D
models compatible with virtual reality and augmented reality programs.
• Currently, of all types of 3D modeling, this is considered one of the most
difficult - 3D models must be flexible and not have “blind zones”.
• You can also use polygon modeling here, but it should be more subtle. Here
are NURMS, or surface modeling units. This is the same as the good old PM,
but each polygon is subdivided (hence the name) into smaller surfaces,
making objects smoother, making them more realistic and flexible - just
what developers need to fill their VR programs and AR.
• What about 3D sculptures? These three-dimensional models take up much
more storage space and require more processing power, which makes them
unsuitable for interactive use.

architects/ you can find more information about AR for architects.

7. MODELING FOR 3D
PRINTING
• As mentioned earlier, there are many uses for 3D models, and they
are not limited to visualization only.
• 3D printing is a relatively recent industry that already promises much
more than insignificant paraphernal production. Electronic devices,
entire buildings, and even functional organs — this amazing
invention revolutionized manufacturing as a whole.
• Thus, it can actually be used to optimize production and, most
importantly, for cheap prototyping. 3D printers cannot create without
any drawings, so they need 3D models in order to “know” what to do.
• The types of three-dimensional modeling that are most common in
this exercise are polygonal modeling for simpler objects and three-
dimensional modeling for more complex ones.
