What are the good methods and software for 3D data analysis?
By building modules, each module has many ready-made development packages to choose from. For example, in the UI module, there are MFC, QT, My GUI (the UI uses MyGUI(Magic3D), and so on. In terms of data processing algorithms, the common ones are Geometry++, CGAL, OpenMesh, PCL, etc.

Commonly used 3D modeling softwares include SketchUp, Blender, 3dsMax, etc. SketchUp is easy to learn and use, and it is a common tool in architectural design, interior design and other fields. In the field of surveying and mapping, three-dimensional modeling of real scenes can be realized in many ways.

Photoshop: application of basic control interface and common tools. Include image mode and difference rate; Creation and application of layers, application of channels and masks; China's calligraphy processing, the application of filters; Make special achievements, etc. AutoCAD: The application and skills of drawing commands, three-dimensional computer drawing, architectural drawing, structural drawing and circuit diagram.

CATIA:CATIA is a three-dimensional engineering design software, which is widely used in aviation, automobile, machinery and other fields. It has powerful modeling and analysis functions, which can help engineers to carry out complex design and analysis.

R is a complete software system for data processing, calculation and drawing. It can provide some integrated statistical tools, but more importantly, it provides various functions of mathematical calculation and statistical calculation, allowing users to flexibly analyze data and even create new statistical calculation methods that meet the needs.
