3D geometric metamorphosis based on harmonic map
Recently, animations with deforming objects are frequently used in various Computer Graphics applications. Metamorphosis (or morphing) of three dimensional objects is one of techn...

Modeling generalized cylinders using direction map representation
For generalized cylinders (GC) defined by contours of discrete curves, we propose two algorithms to generate GC surfaces (1) in polygonal meshes and (2) in cylindrical type of dev...

3D Region of Interest X-Ray CT for Geometric Magnification from Multiresolution Acquisitions
We present an algorithm which allows us to reconstruct a RegionOf-Interest (ROI) from transaxial truncated cone-beam projections. While sometimes it is possible to reconstruct goo...

Natural neighbor interpolation based grid DEM construction using a GPU
With modern LiDAR technology the amount of topographic data, in the form of massive point clouds, has increased dramatically. One of the most fundamental GIS tasks is to construct...
