onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

comerciales. Rhino permite comunicar ideas en el desarrollo, investigación, manufactura, marketing y proceso de construcción de un producto o espacio, antes de ser construido y genera documentos constructivos para la elaboración de los mismos. Permite exportar los archivos a las extensiones comerciales más utilizadas en la industria como DXF, DWG, Illustrator y 3ds entre muchos otros. La gran cantidad de extensiones suplen las necesidades especificas para arquitectura, diseño de producto, calzado, joyería, ingeniería, manufactura y visualización fotorealista.
Grasshopper es una extensión de Rhino que permite el modelado paramétrico sin tener conocimientos de programación o matemáticas avanzadas, facilitando el desarrollo de modelos de alta complejidad a partir de formas simples o complejas.
