LoadPoint3DGrid

Advanced

Module: FoundationBasic

Loads entities from a file of one of available types as an array of points in 3D.

Name Type Description
Input value inFile File
Input value inFileFormat Point3DFileFormat
Input value inRemoveDuplicates Bool Filter will remove duplicate points in point clouds created from STL files.
Output value outPoint3DGrid Point3DGrid

Description

The operation loads an grid of points from a file in one of the standard 3D file formats. Currently the filter supports the following formats:
  • STL (*.stl),
  • PLY (*.ply).
  • PCD (*.pcd).
PLY (Polygon File Format) also known as the Stanford Triangle Format is a format for storing graphical objects described as a collection of polygons. Both ASCII and binary (big-endian and little-endian) versions are supported. Please note that only vertex coordinates can be loaded. Other elements and properties are omitted.

STL (STereoLithography) is a file format commonly used in the stereolithography CAD software. Only binary STL is supported.

PCD (Point Cloud Data) is a file format for storing point cloud data.

Remarks

Warning:All tools applied to a specific device or file should be managed within a single thread to ensure centralized tracking, traceability, and consistency throughout the process.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError Dimensions x, y and z should have 1 element.
DomainError Invalid point dimensions in the PCD file - no x, y, z coordinates.
DomainError Unknown file format in LoadPoint3DGrid.
IoError An error occurred when mapping the PCD file.
IoError An error occurred when unmapping the PCD file.
IoError Error during reading compressed binary file.
