Constraint-Based Design for 3D Shapes
This paper proposes an ATMS-based geometric reasoning system for feature-based 3D solid modeling. Here, every feature is described by a set of geometric constraints such as distances between edges and angles between faces. The system has to evaluate the constraints in order to determine the attributes of all the geometric elements in the features. Therefore, the modeling process can be consider...
متن کاملLaplacian-based Design: Sketching 3D Shapes
The sketch-based shape modeling is one of the most challenging and active problems in computer graphics. In this paper, we present an interactive modeling system for generating free-form surfaces using a 2D sketch interface. Since inferring 3D shape from 2D sketches is an one to many function with no unique solution, we propose to interpret the given 2D curve to be the projection of the 3D curv...

متن کاملConstraint−based modeling of three−dimensional shapes
This paper shows that constraint−based modeling, so far perceived primarily as a graphics technique for man−machine interaction, also provides a viable method for the modeling of complex surfaces. The idea of constraint−based modeling of three−dimensional shapes is described and illustrated by examples. Difficulties related to the practical application of this idea are discussed, and methods fo...
متن کامل2D sketching for the interactive design of 3D shapes
The creation of digital content has recently been identified as one of the grand challenges in the field of Computer Graphics: many applications, from entertainment industry to simulators, require the design of complex 3D worlds including many elements of different nature, from plausible landscape and buildings to vegetation, animals and complex characters, including specific details such as cl...
