The process of building a 3D model, a tutorial on 3D modeling

There are three main types of 3D model construction: Artificial software to build 3D model: this method requires operators to have rich professional knowledge, proficient in using modeling software, and the operation is complex, the cycle is long, and the 3D model of the final component is not very realistic;

3D scanners to build 3D models: This method requires expensive hardware such as 3D scanners. In addition, 3D scanners can only obtain the position information of objects, and most of the texture features on the surface of objects still require a lot of manual work to complete.

The whole process has high cost and long cycle;

Image-based 3D modeling: This method only requires a sequence of different angles of a set of objects** to automatically generate a 3D model of the object with computer assistance. The operation is simple, the degree of automation is high, the cost is low, and the sense of reality is strong.

The display of the 3D model, the user can not only browse the advertising content more clearly and intuitively, its interactivity is user-centric, any angle of all-round browsing and appreciation, and at the same time, according to the requirements of the production of users can intuitively participate in the content, the advertising effect can be imagined. Since then, advertising is not only the leader of the content, but also the participant of the user, the user can browse, can interact, and choose whether to go according to the content, ending the traditional mode of boring click to arrive, and effectively improving the conversion rate of advertising.

The widespread adoption of 3D models will bring a new pattern to the online advertising industry.

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.

The steps for modeling with 3DMAX are as follows: 1. Use various graphic commands to make a basic geometric model; 2. Use advanced modeling commands to trim model details, scale, size, etc.; 3. Set up lights and cameras;

Self-study in 3D modeling takes 15-90 days. The learning time is also based on individual circumstances, if it is just a beginner or a simple elementary modeling, it can be completed in 15 to 30 days. If you want to make a relatively complex model, you need to learn advanced modeling, which takes about 1 to 3 months, and the rest is to practice on your own.

If you want to reduce learning time and improve learning efficiency, choosing a training course is a very efficient way to contact the systematic courses and courseware, and the teacher can guide you from the side, which can save a lot of time. Especially for people who have no foundation or change careers, self-study is time-consuming, and no one can guide them, and it is easy to take detours, be impetuous, and become more and more confused.

Introduction to 3D Modeling:

"3D modeling" is the use of 3D production software to build a model with 3D data through virtual 3D space. 3D modeling can be broadly divided into two categories: NURBS and polygon meshes.

NURBS has a good application for models that require fine, elasticity and complexity, and is suitable for quantitative production purposes, while polygonal mesh modeling relies on the pull surface method, which is suitable for renderings and complex scene animation. All in all, each has its own strengths.

Let's first open the 3DMax software on our computer.

In the top view, enter 5segment.

Right-click the graphic in the perspective view, click Convert to in the pop-up window, and select Convert to Polygon.

Select the edges and pan segments, press the Ctrl key on your keyboard to select the faces of the border, click Extrude, and set the values to etc.

3D solids describe the geometry of a body only through vertices and edges. Peculiarity; The data structure is simple, the amount of information is small, the memory space occupied is small, the response speed to the operation is fast, and the three views can be quickly generated through the projection transformation, and the view and axis side view of any viewpoint and direction can be generated, and the correct projection relationship of each view can be guaranteed.

surface (surface) modeling; A 3D modeling method that can describe the various surfaces or surfaces of an object. Peculiarity; If it is prudent, the surface model increases the topological relationship of the surface and the edge, so it can be blanked, the generation of the profile, the rendering, the intersection calculation, the generation of the CNC tool trajectory, the finite element meshing, etc. However, the surface model still lacks the information of the body and the topological relationship between the body and the surface, and cannot distinguish which side of the surface is in vivo or in vitro, and the physical properties can still not be calculated and analyzed.

solid modeling; It not only describes all the geometric information of the entity, but also defines all the points. Topological information for lines, surfaces, and volumes.
