In order to create a simpler model, usually part of the environment or some other object, modelers are using low polygon modeling(low poly). Previous generation AAA titles, that are created for PS3 or Xbox 360, usually, characters are created with 5000-7000 polygons. For example, in a legendary Half-Life 2, developers have used 2500-5000 triangles per character. Also, if there is a possible situation that there would be a lot of objects in one scene, you should lower the number of polygons per object. The creators of the Unity platform are recommending to use from 300 to 1500 polygons per mesh(object) for a mobile device app, and from 1500 to 4000 for a desktop software. However, there are exceptions, for example when developing for HTC Vive, modelers can create much more detailed 3D models with up to 400 – 600 thousands polygons per scene. Most of the time, he can use up to 70 000 polygons per scene. When a 3D modeler is creating a model for a mobile app, or AR/VR software, his main goal is to achieve a high-quality look using the minimal possible number of polygons.

The polygon consists of vertexes connected by edges. More complex shapes can be broken down into a collection of triangles, this process is called triangulation. The most primitive polygon is basically a single triangle.

Polygon – this is a basic component of any 3D model.

This element has two sets of vertex coordinates and one set of coordinates of itself, that is the sum of vertex coordinates.

Edge – the line that is defined by two vertexes or a connection between two vertexes.

It possesses a set of attributes, such as three-dimensional (x,y,z) and two-dimensional (U, V) coordinates

Vertex – this is the highest point of a dimensional shape.

Modelingįirst of all, let’s define the basic elements that form a 3D model: In this case, a designer is considering the interactivity and stability of the model, the visual aspect is moved to a second place.įor a better understanding, let’s review the process of creating a 3D model. On the other hand, when designing a 3D model for a VR app or a game, the designer is restricted by the game engine, limits of the console or a mobile platform. After all, in cinema all you care about is how realistic your model is, that’s why there are difficult and detailed models used. Creating a model for videos or movies is drastically different from creating a model for a VR app or a mobile game. A lot depends on this factor, for instance, what rules and limits you should look out for designing the model.

When you are creating a 3D model you need to know where it will be used. How to create a 3D model – before you start
