E-LEARNING APPLICATION FOR A BETTER UNDERSTANDING OF SHOES 3D MODELING Authors: Ionesi Dorin, Ciobanu Luminita, Sarghie Bogdan Volume 4 | DOI: 10.12753/2066-026X-14-285 | Pages: 355-358 | Download PDF | Abstract
The paper approaches the specifics of textile E-learning problems concerning the modelling of shoes. A significant number of students have problems understanding and viewing the 3D geometry of complex shapes such as shoes. The current application is intended to simplify this understanding and to enhance their capacity of 3D modelling. The transition between the dimensions of the customers' feet and the final product dimensions require a high accuracy in the shape's definition. The paper presents a different approach to this design using the Google Sketchup application and the Google Sketchup plug-ins. The method is based on the 3D scanning, CAD modelling, analysis and modifications of the shapes in order to obtain a prototype that can be exported in different formats to be used for rapid prototyping.
The Google Sketcup application requires the definition of the 2D shapes corresponding to specific sections in the product and, using the Curviloft plug-in, to extrude them into the final 3D shape. The Curviloft plug-in is a Google SketchUp script mainly used to generate a 3D surface based on different 2D contours and/or straight or curved segments. It works with three different methods: loft by spline, loft along path and skinning. Due to the fact that there are many different methods to define the 3D geometry, the Curviloft script offers various options to define and adjust the geometrical parameters in accordance with the contours configuration and desired 3D final surface.
The designed model is used to illustrate to the students the basis of the skinning operation. The steps are recorded with explanations targeting the specifics of the 3D geometry of shoes and how to create it using a 3D drawing application. The students can watch these steps and repeat them in their own rhythm. Furthermore, this knowledge can be also used in the training of shoe specialists. | Keywords
