3D Scanning
A technology that captures the physical world in three dimensions, converting real-world objects or environments into digital representations. It involves the use of specialized scanners to capture the surface details and geometry, enabling the creation of accurate and detailed 3D models. This versatile technology finds applications in fields such as manufacturing, design, archaeology, healthcare, and virtual reality, facilitating precise digital replication of physical objects for various purposes.

Data Acquisition
Use a 3D scanner to capture data points from the object's surface. The scanner emits light or lasers and measures the reflections to create a point cloud, a collection of 3D coordinates.
Data Processing
Algorithms are applied to process and clean the point cloud data. This step involves removing noise, filling gaps, and refining the data to enhance accuracy.
Texture Mapping
If color information is desired, texture mapping can be applied to the 3D model. This involves projecting the colors from the scanned object onto the corresponding points in the mesh.
Point Cloud Generation
The collected data is processed to create a point cloud, which is a dense set of points representing the object's surface geometry. This point cloud serves as the foundation for the 3D model.
Mesh Generation
The point cloud is then converted into a 3D mesh, where the points are connected to form a surface. This mesh defines the geometry of the scanned object.
Post-Processing
The final 3D model may undergo additional post-processing steps, such as smoothing the surface, optimizing the geometry, or preparing it for specific applications.
