Custom point cloud edit and analysis tools in visual programming: Evaluation of heritage facades

This research project focused on the development of three custom point cloud edit and analysis tools in Grasshopper graphical algorithm editor for Rhino. Employing Volvox, point cloud editing plugin features, the proposed tools collect analyze and represent selected point cloud data to evaluate the photoset acquisition strategy, automate the creation of plane deviation maps and their quantification reports, and to perform targeted color based geometric features detection using the Delta-E CIE 2000 color difference formula. Their development aims to investigate the potential to work with point clouds and transfer common functionality of point cloud edit and analysis software in a design software and to examine if they output meaningful data for the assessment of architectural heritage facades.
