Interactive Image-Guided Modeling of Extruded Shapes

Interactive Face-Replacements for Modeling Detailed Shapes

In this paper, we present a method that allows novice users to interactively create partially self-similar manifold surfaces without relying on shape grammars or fractal methods. Moreover, the surfaces created using our method are connected. The modelers that are based on traditional fractal methods or shape grammars usually create disconnected surfaces and restrict the creative freedom of user...

Safety of Interactive Image-Guided Surgery

Interactive Visualization for Image Guided Medialization Laryngoplasty

Surgical procedures require the physician to use preoperative and intra-operative information for deciding the optimal course of action to be taken on the patient. Medical visualization techniques are used to ‘guide’ the surgeon during the procedure to improve accuracy. We are presenting a visualization approach for image guided medialization laryngoplasty. A brief background is provided to des...

Modeling Shapes in an Image Database System

Due to the complex modeling requirement of data handled by image and spatial databases, they are most often built on top of object-oriented or object-relational databases. In the DISIMA image database, an image is composed of salient objects and a salient object has a shape which is a geometric object. The object-oriented modeling of shapes potentially conflicts with the mathematical definition...

Interactive Modeling of Support-free Shapes for Fabrication

We introduce an interactive sculpting approach that enables modeling of support-free objects: objects which do not require any support structures during 3D printing. We propose three operators – trim, preserve, grow – to maintain the support-free property during interactive modeling. These operators let us define brushes that perform either in an unconstrained manner (adapting the shape to the ...
