## Pages in this subsection

- [Easy3D Code Snippets](index.html.md): Browse code snippets demonstrating Easy3D usage in C++, C#, and Python for eVision machine vision applications.
- [Using EFilters to Remove the Noise on a ZMap Based on the Standard Deviation Code Snippet](efilters1.html.md): The code below removes pixels with a standard deviation higher than a defined threshold in a ZMap.
- [Using EFilters to Remove the Noise on a ZMap Based on the Derivation from Neighborhood Code Snippet](efilters2.html.md): This code snippet applies a low-pass filter to a ZMap, then removes pixels deviating from their neighborhood beyond a set threshold.
- [Aligning Point Clouds Code Snippet](aligningpointclouds.html.md): This code snippet shows how to align two 3D point clouds using feature-based registration.
- [Reducing the Size of a Cloud with Random Decimation Code Snippet](randomdecimation.html.md): The code reduce the size of a cloud by removing points randomly.
- [Reducing the Size of a Cloud with Grid Decimation Code Snippet](griddecimation.html.md): The code reduce the size of a cloud by removing points to keep at most one per cell of a regular grid.
- [Using Photometric Stereo Code Snippet](photometricstereo.html.md): The code shows how to use Photometric Stereo from calibration to retrieve the results.
- [Using Flat Images to Improve Photometric Stereo Code Snippet](photometricstereousingflat.html.md): The code shows how to use flat images to improve photometric stereo's results.
- [Performing Plane Leveling on Point Clouds Code Snippet](pointcloudplaneleveling.html.md): The code shows how to perform plane leveling on point clouds.
- [Performing ZMap Leveling Code Snippet](zmapleveling.html.md): The code shows how to perform ZMap leveling either by specifying a Region or using EPlaneFinder.
- [Using an ERegion to Crop a ZMap Code Snippet](zmapcropping.html.md): This code snippet shows how to crop a ZMap to keep only the pixels inside a polygonal region of interest.
- [Add an Attribute to an EPointCloud with Initial Data Code Snippets](addattributetocloud1.html.md): The code shows how to add an attribute to a cloud when you already have the data.
- [Add an Attribute to an EPointCloud without Initial Data Code Snippet](addattributetocloud2.html.md): The code shows how to add an attribute to a cloud when you don't have the data.
- [Retrieve an Attribute from an EPointCloud Code Snippet](retrieveattributefromcloud.html.md): The code shows how to retrieve an attribute from a cloud.

## Optional
