The basic factors of spatial three-dimensional modeling (1)

According to the definition of geometry, a solid plane is a trajectory of plane motion. For example: a square plane, moving along a certain direction, the trajectory can be presented as a cube or rectangular parallelepiped. The rectangular plane rotates on one side of its axis, and the other side of the rectangle (ie, the plain line) can form a trajectory on the surface of the cylinder. A circular plane, with its diameter as its axis, undergoes a rotational motion and its trajectory can be formed as a sphere surface. . . . . Wait. In addition, the superimposition of several shapes, or the digging of another shape from one shape, can form a variety of new shapes. Or, a number of small bodies gather together, and the closed space that is defended by the wire group frame, and the plane, the curved surface, the curved surface, the curved surface, the curved surface, the stretched structure, or the enclosed space, can also form a three-dimensional shape. .

First, the basic three-dimensional shape and emotional characteristics

A three-dimensional object, with length, width, and depth, is the three-dimensional space it occupies. The cube is one of the most basic forms of a three-dimensional object. It is composed of three parts: angular, ridgeline and three-dimensional surface. A cube with eight edges, twelve ridges, and six planes consisting of regular hexahedrons. In our lives, the vast majority of three-dimensional objects are not only simple positive cubes, but their images are ever-changing. The corners are sharp corners, but also have round corners, some are right angles, and some are acute or obtuse angles. Its ridges have straight lines and curves. In terms of quantity, some are composed of the most basic number of six planes, and some increase or decrease. The shape and quantity of its performance are also based on changes in the image, increasing or decreasing, and having a round circle...

To sum up, the most basic forms are the following four:

1. Plane geometry

It is a closed space formed by connecting more than four planes with their boundary lines. Or, its cubic entities can all be called planar geometric bodies. Such as: positive triangular pyramids, positive quadrangular pyramids, positive cubes, cuboids, positive pentagonal prisms, or other planar multidimensional surface. . . Wait.

The characteristics of the plane geometry: The surface of the plane is a plane, and its ridge line is a straight line. Therefore, people's psychological feeling is: concise, generous, dignified, and its strong stability. Therefore, it can symbolize a stable, serious, calm and other emotional personality. In the world's famous buildings, such as: Egypt's "pyramid" is a right quadrangular pyramid, its shape appears to be stable, high and magnificent. Into: China's great building "Wanli Great Wall", the wall shape and the middle of the construction of the "Settling" and "Beacon Tower." Their image is basically the shape of a cube. The feeling for people is extremely magnificent. Another example: the shape of the exhibition booths for the exhibition is a rectangular body composed of straight lines. Since its use is to display exhibits, the variety of colors and colors of the exhibits at the time of exhibitions are varied. The exhibition stand should not be changed too much. It should be concise and generous. In short, the plane geometry, which is mainly composed of straight lines, and acoustic planes, can have a simple, clear, straight, and stable design. Its emotional character is basically the same as the straight line in "Plane Composition". It is a symbol of a male character.

2. Geometric surface three-dimensional

It is a block or a convolution formed by geometric surfaces. The three-dimensional shape of the geometric surface is formed by a plane with a geometrically curved linear edge, which moves in a straight line direction, and the tricks are then presented back to the total geometrically curved surface cylinder. If the opposite side is a straight line, use the straight line side of this plane as the axis to perform a rotational motion. The motion trajectory of this plane is a geometrical surface.

In daily life, the common three-dimensional basic shape is a lot. Such as spheres, cylinders, cones, and other cubes or gyrators with geometric curve variations. In the vessels used in everyday life, common shapes such as lampshades, cups, pots, pots, funnels, tires, etc. The three-dimensional shape of the geometric surface, its order is strong, the surface is a geometric surface, gives the impression that the person is serious and dignified, there are changes in the curve, is the ideal design of home utensils and other designs.

3. Freeform three-dimensional

It is a three-dimensional shape composed of freeform surfaces. Including: Freeform body and freeform surface formed by the body of revolution. Such as: tea cups, wine bottles, electric irons, ashtrays and other shapes. Most of these shapes are symmetrical, and their curves give people a feeling of beauty and liveliness as well as strong order. If the surface is changed too much and the curves in all aspects are inconsistent, it is easy to lose the overall sense and appear trivial. Some shapes can also be properly combined with straight lines, which will enhance their stability and strong feeling.

4. Natural form

Mainly refers to some accidental forms naturally formed in the objective environment. Since various substances are formed under different conditions, a variety of natural shapes can be produced. There are few artificial components of this type of shape, and most of them reflect the simple natural form of the shape. Such as: natural crystal stone shows a clear and transparent material characteristics. Its shape structure is composed of a myriad of small planes, composed of cubic crystal blocks, the image of a variety of changes, is a natural beautiful decorations. Another example: Pebbles on the seashore, it is a variety of different components of the stone, washed through the sea for many years and months. The natural image formed. This is a beautiful freeform body. The surface is smooth and delicate, fully displaying the rich color of the material itself and its gorgeous texture. Therefore, it has become a common natural jewelry in people's lives. Another example: volcanic grey stones, corals in the sea, roots of old dry trees, shells, feathers of feathers, etc. All have extremely rich and gorgeous natural color and beautiful shape. Some objects can be directly used to decorate and beautify life, and some shapes can be used as a luxury decoration after a little processing. All of these can be used as materials for designers of fine arts and good references, and they can gain no enlightenment from them.
