What Is Reverse Engineering Malware?

Reverse engineering, some people also call reverse engineering, English is reverse engineering, the main idea is to derive specific implementation methods through analysis based on existing things and results.

Reverse engineering software

For example, you see that an exe program written by someone else can make some beautiful animation effects.

Imageware
Imageware, produced by the American EDS company, is the most famous reverse engineering software, and is being widely used in the design and manufacturing fields of automotive, aerospace, aerospace, consumer appliances, molds, computer parts and other fields. The software has a large user base. There are well-known international large companies such as BMW, Boeing, GM, Chrysler, Ford, raytheon, Toyota, etc., while domestic companies include Shanghai Volkswagen, Shanghai Jiaotong University, Shanghai DELPHI, Chengdu Aircraft Manufacturing Company and other large enterprises.
In the past, the software was mainly used in the aerospace and automotive industries, because these two fields have high aerodynamic performance requirements, and aerodynamics must be carefully considered at the beginning of product development. The conventional design process first designs the structure according to the needs of industrial modeling. After making the sludge model, it is sent to the wind tunnel laboratory to measure the aerodynamic performance, and then the model is repeatedly modified according to the experimental results until satisfactory results are obtained. The resulting sludge model is the model that meets the needs. How to accurately input the shape of the sludge model into a computer into an electronic model requires reverse engineering software. First, use a coordinate measuring instrument to measure the dot matrix data of the model surface, and then use reverse engineering software (for example: Imageware surfacer) to process the class 1 surface.
With the advancement of science and technology and the continuous improvement of consumption levels, many other industries have also begun to adopt reverse engineering software for product design. Take the mouse produced by Microsoft as an example. As far as its function is concerned, only three buttons are needed to meet the needs of use. However, how to make the mouse feel the best, and it is not easy to produce fatigue after long-term use. Issues that manufacturers need to seriously consider. Therefore, Microsoft first produced several models based on ergonomics and submitted them to the user for evaluation. Then, the model was directly modified according to the evaluation opinions until everyone was satisfied. Finally, the model data was generated using the reverse engineering software Imageware to generate CAD data. When the product was launched to the market, it quickly gained widespread recognition from users due to its novel appearance, smooth curves, and good hand feel, in line with ergonomic principles, and the market share of the product increased significantly.
The main products of Imageware reverse engineering software are:

Imageware uses NURB technology, and the software is powerful and easy to apply. Imageware has low hardware requirements and can run on various platforms: UNIX workstations and PCs. The operating system can be UNIX, NT, Windows95 and other platforms.
Imageware has advanced technology in reverse engineering. Once the product is launched, it has captured a large market share. Software revenue is growing rapidly at an annual rate of 47%.
Imageware's process of processing data follows the principle of point-curve-surface. The process is simple and clear, and the software is easy to use. The process is as follows: 1. Dot process reads dot matrix data.
Imageware can receive almost all three-dimensional measurement data, in addition to other formats, such as: STL, VDA, etc.
Align the separated dots together (if needed).
Sometimes due to the complex shape of the part, not all data can be obtained in one scan, or the part cannot be scanned in one scan. This requires moving or rotating the part, which will result in a lot of separate lattices. Imageware can use special point information such as cylindrical surface, spherical surface and plane to accurately align the dot matrix.
Judge the dot matrix to remove noise points (that is, measurement error points).
Due to the limitation of measurement tools and measurement methods, some noise points sometimes appear. Imageware has many tools to judge the dot matrix and remove the noise points to ensure the accuracy of the results.
Plan how to create surfaces by visualizing dot matrix observations and judgments.
A part is composed of many individual curved surfaces. For each curved surface, it can be judged in what way to construct according to the characteristics. For example, if the surface can be directly generated from a grid of points, you can consider directly using this point matrix; if the surface requires multi-segment curve skinning, you can consider the segmentation of intercept points. Planning ahead can avoid detours in the future.
Create a grid of points or segments of points as needed.
Imageware can provide a variety of point mesh and point segmentation tools. These tools are flexible and convenient to use, and can also generate multiple point segments at one time.
2. The curve creation process judges and decides what type of curve to generate.
The curve can be exactly through the lattice, it can also be very smooth (capturing the main shape of the curve represented by the lattice), or somewhere in between.
Create a curve.
Create curves as needed and change the number of control points to adjust the curve. Increasing the number of control points results in a good shape fit, while decreasing the number of control points results in a smoother curve.
Diagnose and modify curves.
The smoothness of the curve can be judged by the curvature of the curve, the consistency between the curve and the lattice can be checked, and the continuity of the curve and other curves (connection, tangency, and curvature continuous) can be changed. Imageware provides many tools to adjust and modify curves.
3. The surface creation process decides what kind of surface to generate.
Like the curve, you can consider generating a more accurate surface, a smoother surface (such as a class 1 surface), or both, which can be determined according to the product design needs. .
Create surfaces.
There are many ways to create a surface. You can use a dot matrix to directly generate a surface (Fit free form). You can use curves to generate a surface through skinning, sweeping, and four boundary lines. You can also combine the information of the dot matrix and the curve to create a surface . Surfaces can also be generated from other angles such as rounded corners, bridge surfaces, etc.
Diagnose and modify surfaces.
Compare the degree of fit between the surface and the dot matrix, check the smoothness of the surface and the continuity with other surfaces, and modify it at the same time. For example, you can align the surface with the dot matrix. Reconstruct the surface.
It is precisely because Imageware has unparalleled power in other software in terms of computer-aided surface inspection, surface modeling, and rapid prototyping that makes it a leader in reverse engineering.

RapidformXO Redesign allows engineers to capture the design intent and design parameters of actual objects that may lose their defining features or have no CAD models at all during the manufacturing process. Three-dimensional scanning technology and RapidformXO Redesign provide manufacturers with the freedom and flexibility to extract design parameters of actual objects, including prismatic features and freeform surfaces. Because the CAD model generated in RapidformXO Redesign is fully parameterized, designers and engineers can modify the design parameters of actual objects in RapidformXO Redesign or another downstream CAD system, thereby perfecting this model and enabling it to be mass-produced.

RapidformXO Redesign is an innovative software solution that can help engineers create parametric CAD stereograms using 3D scanned data and polygon data. XOR uses standard stereo and graphic modeling workflows and a user interface familiar to engineers, so this software solution requires little training, and can reduce the time required to process 3D scan data.
