3D modelling. Abstract: We describe a free-form stroke-based modeling system where objects are primarily represented by means of variational surfaces.

Our approach uses variational implicit surfaces as a geometrical representation for free-form shapes. We have implemented new modelling operations to support ...

With the advent of sketch-based methods for shape construction, there's a new degree of power available in the rapid creation of approximate shapes.

In this paper, we discuss our preliminary efforts at using variational implicit surfaces [Turk, 2000] as a representation in a free-form modeler. We also ...

In this paper, we have presented a stroke based modeller application for 3D free form modelling using variational implicit surfaces. The different ...

This is done by projecting the 2D strokes on the sphere with the center at the eye point and then viewing them in perspective. This system's goal is different ...

Then, depth values are assigned to the resampled 2D points to form 3D contours. Variational implicit surfaces are fitted to the 3D contours to generate 3D blobs ...

May 6, 2003 · In this paper, we discuss our preliminary efforts at using variational implicit surfaces [Turk, 2000] as a representation in a free-form modeler.

A complete modeller application using variational implicit surfaces that can create and manipulate shapes using sketches on a perspective or parallel view ...
