Three-dimensional appearance is obtained by using Scanning Electron Microscopes (SEM).

Here are the steps:

1. The sample is prepared and placed into the SEM chamber.
2. The SEM creates a focused beam of electrons that scans back and forth across the surface of the sample.
3. As the electron beam interacts with the sample, it produces various signals (secondary electrons, backscattered electrons, etc.) that contain information about the sample's surface topography and composition.
4. These signals are detected and transformed into an image.
5. The SEM is capable of producing high-resolution, three-dimensional images because it captures information from a very small area of the sample each time it scans. This allows it to create an image with depth, which gives the appearance of three dimensions.
6. The images can then be further processed and analyzed to study the sample in detail.
