Descriptive: Interactive 3D Shape Modeling from A Single Descriptive Sketch

Constructing 3D Objects from a Single Sketch

The goal of this term project is to explore approaches for constructing a three-dimensional object from a two-dimensional sketch. In this report, the background knowledge is introduced followed by a survey of previous methods. The method of surface mesh generation is analyzed in morphology. Based on the analysis, algorithms are constructed to implement the mesh generation and the developed inte...

3d Modeling of Trees from Freehand Sketch

We present an interface for quickly and easily modeling 3D trees from freehand sketch. The system generates a 3D geometry from 2D sketch on the basis of our observation that trees spread their branches uniformly. Our system also supports several interfaces for editing the 3D tree by drawing additional strokes. These editing operations include adding a branch, cutting a branch and erasing a bran...

Demonstrating the Transferability and the Descriptive Power of Sketch-Map.

Increasingly, it is recognized that new automated forms of analysis are required to understand the high-dimensional output obtained from atomistic simulations. Recently, we introduced a new dimensionality reduction algorithm, sketch-map, that was designed specifically to work with data from molecular dynamics trajectories. In what follows, we provide more details on how this algorithm works and...

Reconstruction of a 3D Object From a Single Freehand Sketch

Extended Abstract This presentation proposes a new approach for reconstructing a three-dimensional object from a single two-dimensional freehand line drawing, as means for a CAD user interface. Reconstruction is the inverse projection of the sketched geometry from two dimensions back into three dimensions. While humans can do this reverse-projection remarkably easily and almost without being aw...
