# eVision > eVision 26.10.0-beta.2.dev documentation 2026, Euresys ## Pages in this subsection - [Easy3D](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](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](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](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](randomdecimation.html.md): The code reduce the size of a cloud by removing points randomly. - [Reducing the Size of a Cloud with Grid Decimation](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](photometricstereo.html.md): The code shows how to use Photometric Stereo from calibration to retrieve the results. - [Using Flat Images to Improve Photometric Stereo](photometricstereousingflat.html.md): The code shows how to use flat images to improve photometric stereo's results. - [Performing Plane Leveling on Point Clouds](pointcloudplaneleveling.html.md): The code shows how to perform plane leveling on point clouds. - [Performing ZMap Leveling](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](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](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](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](retrieveattributefromcloud.html.md): The code shows how to retrieve an attribute from a cloud. ## Optional - [Top-level llms.txt](../../../../llms.txt): Complete documentation index.
