Research Area

Laboratory

　"Interactive High-Performance Terrain Visualization for Fukushima Prefecture" project In collaboration with Prof. S. Sedukhin, The University of Aizu, Japan. Supported by the Fukushima Prefectural Foundation for Advancement of Science and Education.

　"CIS project": Java implementation of Turtle graphics for 3D geometric modeling, visualization, and painting

Research Projects

The heart of my work is hybrid volume modeling, which includes mathematical models, numerical methods, software algorithms and programming realization. Highly detailed complex objects can be produced and we are able to apply set-theoretic operations, transform objects, and control deformations according to the given constraints or main topological features of the shapes, by producing more complex ones.

Some examples of this approach are on the Web site: http://www.k.hosei.ac.jp/~vsavchen/Pictures.htm

Ongoing projects

  • "Growing shapes: Reconstructing missing parts of geometric objects". Potential application areas include shape modification and 3D animation
  • "Volume modeling: Evolutionary optimization of functionally defined shapes". Potential application areas include lens design.
  • "Interactive deformation of a virtual object with the help of CyberGlove". Potential application is a puppet animation
  • "3D haptic sculpting of geometric shapes". Potential application areas include shape design in car and other industries, computer art, medicine, in particular, prosthetic design.

Typical/proposed master projects

  • Converting Elevation Contours to a Grid: Hypsographic (elevation) data can be represented in various formats, including contour lines. The goal of the project is to develop software interface for converting data from the contour format to an array, or grid, of elevations
  • Java and VRML Execution Model for Animation

The networking programming language Java and the 3D graphics standard for the Internet, the Virtual Reality Modeling Language (VRML) are two tools that allow us to build rich, interactive 3D scenes - scenes that and where

People can navigate through and can interact with
VRML provides the essential 3D building blocks for constructing your own cyberworlds
Java is the glue that animates the worlds and links them to the World Wide Web

Goal of the project

  • To give students a grounding in the mechanisms supported by VRML 2.0
  • To show how to use Java to build animated 3D worlds
  • To develop an application whereby objects can be animated.

Shape transformations with constraints for animation applications

Shape transformation is one of basic operations in computer graphics. Examples of applications can be found in such fields as animation and computer-aided design (CAD). In CAD, shape transformation methods become important because they allow customized objects to be generated according to some measurement data. The problem concerns transformation of a given geometric shape into another in a continuous manner. The goal of the project is to develop a software tool for animation where

  • Geometric models are based on measured data
  • A space-mapping technique based on compactly supported radial-based functions provides constraints for collision avoidance and the function mapping defines metamorphosis between two implicitly defined shapes.

2D Warping and Sample-Based Approximation for Flame Animation

Visualization of different natural phenomena has three main problems:

  • Sfficient quality to display high-resolution images
  • Motion simulation
  • Calculation speed

The goal of the project is to develop a software algorithm for flame animation to obtain visually smooth images in a reasonable time.
