Introduction

3D computer modeling is an innovative research field that is becoming increasingly important in the modern world. The term "3D modeling" refers to the process of creating three-dimensional objects in virtual space using computer technology. This topic has not only gained wide acceptance in the entertainment industry and graphic design, but has also become an important tool in engineering, architecture, medicine and other fields.

3D computer modeling is the process of creating three-dimensional objects using specialized programs and algorithms. This includes various techniques for describing the shape, textures and lighting of objects in order to achieve the most realistic visual representation.

The development of 3D modeling technology has significantly expanded the possibilities of visualization and creativity in various fields. In architecture, for example, 3D modeling allows architects and customers to interact with virtual models of buildings even before construction begins. In engineering, this method is used to create prototypes and optimize designs. In medicine, 3D modeling is used to visualize internal organs, train surgeons, and plan complex operations.

Since the beginning of its appearance, 3D modeling has gone a long way. Starting with simple wire models, it moved on to more complex surface and solid-state models. In the modern era, we are witnessing not only an improvement in image quality, but also the development of virtual reality, which allows you to literally immerse yourself in the created 3D models. An example of animation of a created 3D model is shown in gif format.

Principles of computer 3D modeling

Principles of building three-dimensional models:

Accuracy and scalability. Three-dimensional models are built with precision and scalability in mind. This is important to ensure the correct proportions and ratios between objects, as well as the possibility of using models at different scales.

The hierarchy of objects. The principle of object hierarchy is applied in 3D modeling. This allows you to create complex scenes where objects can be nested inside each other, making it easier to control and animate.

Modeling methods. There are several modeling methods, such as solid-state, surface and wire modeling. Each method has its advantages and is applied depending on the specific tasks.

Principles of visualization and display:

Surface display. For visualization of 3D models, it is important to correctly display their surface using textures, materials and lighting in order to achieve realism.

Rendering techniques. Rendering is a key stage of visualization. The principles of rendering include choosing the right renderer, adjusting lighting parameters, choosing materials and textures, which ultimately creates a photorealistic image.

Principles of animation and interaction:

Frames and key points. Animation in 3D modeling is based on the use of frames and key points. Setting key points allows you to determine the position of an object at a certain point in time, and then the computer interpolates between them.

Rigging and skeletal animation. The principles of rigging and skeletal animation are used to bring objects to life. This includes creating bones and joints so that objects can animate, simulating the movement of real entities.

Principles of optimization and efficient use of resources:

Polygon management. Effective management of the number of polygons in models is important to optimize performance. This includes the use of LODs (levels of detail) and optimized modeling techniques.

Optimization of textures and materials. Texture sizes and formats, as well as material settings, must be optimized to ensure fast loading and smooth operation of applications.
