Progressive Surface Modeling Based On 3D Motion Sketch
نویسنده
چکیده
This paper presents a novel progressive surface modelling method to construct a freeform surface incrementally based on 3D motion sketches that represent the boundary and interior characteristic curves. The approach can construct a base surface model from multiple boundary curves and support incremental surface updating from interior characteristic curves which may cross the boundary curves or not. The base surface is first constructed as a regular Coons surface. Upon receiving an interior curve sketch, it is then updated. With this progressive modelling process, a final surface with multiple sub-surfaces can be obtained from a set of unorganised curves and exchanged to a commercial surface modelling software for modification in detail. The approach has been tested with examples. It is capable of dealing with unorganised design curves for surface modelling and easy to use in conceptual design. Key-Words: motion sketch, surface modeling, conceptual design, boundary curves, interior curves.

متن کاملInteractive Geometric Modeling Using Freehand Sketches
CAD software and similar modeling systems can show 3D object models created by designers, but these advanced 3D systems demand precise data about the 3D object, especially in the steps of inputting data and making freeform surfaces. Although it has become common to use CAD/CAM systems to increase the efficiency of the industrial design process, traditional sketching is often more efficient in t...
متن کاملAn evaluation of user experience with a sketch-based 3D modeling system
With the availability of pen-enabled digital hardware, sketch-based 3D modeling is becoming an increasingly attractive alternative to traditional methods in many design environments. To date, a variety of methodologies and implemented systems have been proposed that all seek to make sketching the primary interaction method for 3D geometric modeling. While many of these methods are promising, a ...
متن کاملUniversal attraction force-inspired freeform surface modeling for 3D sketching
This paper presents a novel freeform surface modeling method to construct a freeform surface from 3D sketch. The approach is inspired by Newton’s universal attraction force law to construct a surface model from rough boundary curves and unorganized interior characteristic curves which may cross the boundary curves or not. Based on these unorganized curves, an initial surface can be obtained for...
