# Scanning

{% hint style="info" %}
Tip: Different scanning types will produce different types of data, and the data formats for point clouds and models will also be different. Models are textured triangular meshes, while point clouds are simply 3D points.

**Points:** The scan is recorded in point cloud format without generating triangle meshes. It can be exported in formats such as Obj, Ply, Bin, XYZ, etc.&#x20;

**Room:** Room scanning is done using RoomPlan, and can export in USDZ format.&#x20;

**Model:** Model scanning generates a real-time triangle mesh. During the scan, the surface flatness is indicated by the color of the surface normals. It is recommended to scan the object as completely as possible according to the prompt.

### <img src="/files/WjQt04Ebuve9fPMuPaic" alt="" data-size="line">     **Distance settings:**&#x20;

The scanning range is 0.4m to 5.0m, with a default distance of 3m. You can modify the maximum scanning distance according to your needs.

### <img src="/files/PBOULKqKb1uHc5Di3kco" alt="" data-size="line"> **Scan resolution:**

Scan resolution refers to voxel size, which is the size of the smallest grid in space. The resolution range is from 5mm to 30mm. A smaller resolution means a finer level of detail, but it also requires more memory. A larger resolution means coarser details, but it is suitable for scanning large areas of data.

{% hint style="info" %}
Tip: If the resolution is set too small, such as 5mm, and the scanning distance is set very far, such as 5m, it will occupy a very large memory and may not be able to scan a large range, or even cause the App to crash.
