3D modeling has firmly entered our lives, partially or completely rebuilding some types of business. In each industry in which 3D modeling has brought its changes, there are both its own specific standards and unspoken rules. But even within the same industry, the number of software packages can be so many that it can be very difficult for a beginner to figure out and navigate where to start. Therefore, for starters, let’s look at what types of 3D-modeling are and where they are used.
We can distinguish 3 large industries that today are impossible to imagine without the use of three-dimensional models. It:
With the first we come across almost every day. These are films, animation and 90% of computer games. All virtual worlds and characters are created using the same principle – polygonal modeling.
Polygons are called these triangles and quadrangles.
The more polygons per model area, the more accurate the model. However, this does not mean that if the model contains few polygons (low poly), then this is a bad model, and a person’s hands are not from there. The same thing, it cannot be said that if the model Over999999 has polygons (High poly), then this is cool. It all depends on the destination. If, for example, we are talking about massively multiplayer games, then imagine what it will be like for your computer when you need to process 200 characters around, if all of them are high poly?
Polygonal modeling occurs by manipulating polygons in space. Pulling, rotating, moving, etc.
The pioneer in this industry is Autodesk (known to many for its AutoCAD product, but more about it later).
Autodesk 3Ds Max, and Autodesk Maya, have become the de facto industry standard. And I began my acquaintance with 3D models as a 15-year-old teenager with 3Ds Max.
What do we get when we make such a model? We get a visual IMAGE. Gamers sometimes say, “I fell through the textures” in the game. In fact, you fall through the polygons on which these textures are superimposed. And the fall into infinity occurs precisely because there is nothing behind the image. Basically, the resulting images are used for RENDER (final image rendering), in the game / in the movie / for pictures on the desktop.
Actually, I at one time tried to “blind” something to make a cool render (then it was much more difficult).
Speaking of modeling. There is such a direction as 3D-sculpting. In fact, the same polygonal modeling, but aimed at creating basically complex biological organisms. It uses other polygon manipulation tools. The process itself is more like minting than 3D modeling.
If the polygonal model is made in the form of an enclosed volume, such as the same sculptures, then thanks to modern 3D printing technology (which resides in almost any shape), they can be realized.
