Getting Started

The Voxel Cloud Generator (VCG) is a tool with four main functionalities, one per tab:

Print File Generator: generate print files for printing on the CERES system according to the required Print File Format
Voxelizer: convert STL files to CERES print files via Exaddon’s cloud service
Log Viewer: load CERES print log files for display and analysis
Iontip Calibrator: obtain the pressure - voxel diameter relation for an iontip from print log files

General remarks

The VCG is written in Mathworks MATLAB.
The VCG is designed to complement the CERES operating software (CAPA).
The primary function of the VCG is to generate print files in .csv format that can be loaded into CAPA.
The VCG also generates a .mat file with metadata for each (.csv) print file. CAPA requires both the .mat and .csv to be present.
CAPA generates print log data that can be moved to and visualized in the Log Viewer tab.
Complete log data access and further analysis tools are available through MATLAB itself.

A supported version of Mathworks MATLAB is installed (R2021b through R2026a; R2026a recommended for VCG 2.6). Other MATLAB versions may not work. Check README.md for the exact supported list.
To fetch print log files created by CAPA, the VCG uses the <BaseExportDirectory> value of CAPA defined in the settings file located in %localAppData%/Exaddon/CAPA/settings.xml.
It is strongly recommended to use the Windows operator account at all times while printing. The <BaseExportDirectory> should be set accordingly.

Start MATLAB and set the Current Folder to the folder chosen at installation that contains VCG.p.
In the MATLAB command window, type VCG and hit enter.
