I want to study 3D majors! Get started with 3D modeling

If you want to learn systematically, you can consider signing up for a live online class, and recommend CGWANG's online class. The teacher speaks carefully, you can watch it back after the class, and there are also the same type of recorded classes that you can learn for free (give away lifelong VIP).

Among the training institutions in the field of "3D modeling", [Wang's Education] is the leader in China, and it does not join the branches, but is a chain campus directly operated by the headquarters. Different from many other large institutions of the same type: each campus of Wang's Education is physically face-to-face, the teachers are hand-in-hand, and there are special class teachers from morning to night, and the liver-bursting learning mode will improve quickly, especially suitable for students with poor foundation.

I'm coming to you. There are several ways to learn three-dimensional, if you are still a student, you don't need to participate in the training course, because that is too expensive, and the training course will not teach you anything else except for handing you in, one is the technical reservation, the other is that the teachers of many training institutions themselves have no practical work experience, just with a mouth to fool people, your advantage is time, you can find some practical tutorials to study carefully, if you have strong art skills, you will focus on models and materials, outstanding performance talent, focus on animation, neither of them, Focus on special effects. Don't expect to be proficient in everything, because many companies nowadays work in modules, and you won't be very useful if you know everything, so you might as well be proficient.

After graduation, find a company (regardless of salary) for a three-month internship, and you will officially enter the industry.

If you are now in the stage of looking for a job, time is pressing, then you can consider looking for a training course to get started, at this time don't think about the problem of money, to find the kind of training course that can have an actual job position for you to intern after the training, remember, the actual project internship is the most important, listening to the teacher's lecture is just the basic entry, but be wary of the deception of the training institution, to confirm whether there is a real internship opportunity, if you can't find this kind of training institution, there are two options, one is to find a cheaper crash course, three to six monthsAfter graduation, you should study carefully, do some works and find a unit for an internship for three months (regardless of salary), and learn the key points during the internship; The second is to go to IDMT, study for a year, the best training institution in China, it is best to go to Shenzhen headquarters to study, and then find a job after completing the study, so that the tuition is expensive, but the teaching quality there is the best, they are combined with actual production and teaching in one. You can go to their official website to take a look, as for Mars and crystal stones, don't waste money, they rely on brands to make money.

How you choose depends on your actual situation.

It depends on which direction you want to develop: architecture, interior, games, film and television post, CG, characters or scenes.

When you first started studying, you bought a good book by yourself, and you learned most of the basic things than doing it all over again. After that, it depends on which aspect of your network develops.

Nowadays, the game industry is more popular, and you can try to make game character models or game scenes.

If you want to sign up for a class.

In order to get a good job, it is recommended that you go to the training institutions of game companies, such as: Perfect, Kingsoft and so on. They all have their own training institutions.

If you do film and television post-production.

You'll have to go to a better training facility.

It is recommended that you do your own research.

It's okay to sign up for an intensive class for 1-3 months.

The Introductory 3D Modeling tutorial is a three-step tutorial:

First, CAD 3D modeling should first be familiar with the relationship between the world coordinate system and 3D space; The second is to master the CAD user coordinate system and the use of multiple views, and must be familiar with the operation of the area and polylines; As for the basic three-dimensional drawing exercises, it is all about repeated training to master the characteristics of each one.

Remember: every CAD command has its own tricks, explore and master them.

Second, the world coordinate system is a Cartesian coordinate system used to determine the position of the plane or space point when CAD is drawing, the forward direction of each coordinate and the rotation direction of the other two coordinates must conform to the right-hand rule, and the three-dimensional world coordinate system symbol symbol of CAD in the plane drawing has a "W" in the coordinate symbol diagram.

Generally, the x-y plane is understood as the horizontal plane, and the z-axis direction represents the height distance, that is, the "z" value is equivalent to the elevation command "elev" used to determine the height of the x-y horizontal plane.

Note: No matter how complex your 3D modeling design is, there must be a basic coordinate system that cannot be changed during the drawing process, otherwise, the disorder of the drawing direction will make you in trouble!

3. How to flexibly use 3D coordinates, in the process of 3D solid modeling, the coordinate system should be changed frequently, so as to facilitate the drawing. The world coordinate system of CAD is unchanging, mainly the transformation of the user's coordinate system, and its command is "UCS", which can complete the functions of translation, new coordinate direction, rotation and so on.

3D model composition:

1. Grid. A mesh is made up of a number of point clouds of an object, which are used to form a 3D model mesh that includes 3D coordinates (XYZ), laser reflection intensity (intensity), and color information (RGB), and is finally drawn into a mesh, which is usually composed of triangles, quadrilaterals, or other simple convex polygons, which can simplify the rendering process. However, meshes can also include objects made up of ordinary polygons with holes.

2. Texture. Texture includes not only the texture of the surface of the object in the usual sense, even if the surface of the object is uneven, but also includes the color pattern on the smooth surface of the object, also known as the texture of the stool, which can make the object look more realistic when the texture is mapped to the surface of the object in a specific way.

the technique of texture mapping mesh to impart image data; After processing the image obtained from the shooting of the object, the texture mapping on each mesh is finally formed into a 3D model.
