Abstract
We propose a design and an implementation of a system
for interactive walkthrough of large CAD models.
The system will be interfaced with the immersive
hardware and used for applications like immersive
modeling, design evaluation, simulation and training.
Our emphasis is to develop better algorithms, software
systems and demonstrate their applications. The set of
problems include:
- Hierarchical and multiresolution representation
of models for fast display.
- Fast techniques for visibility culling.
- Use of textures for representing geometry and
radiositized meshes.
- Interactive display of large polygonal,
sculptured and solid models on current graphics systems.
- Interactive collision detection between
geometric models and collision response using
haptic interfaces.
We expect to integrate the systems with the graphics
and immersive hardware and use them for immersive
modeling and design evaluation of submarines and ship
models. The goal is to create an environment where the
user will explore a model of a submarine or a ship in
the same way as he would explore a real one -- by
walking around it. Eventually such systems
will also be useful for experiential training, crisis
management and integrated damage control training
technology.
We have been collaborating with researchers at
Electric Boat and Newport News Shipbuilding and
expect to transfer the technology to these
organizations. The complexity of the large-scaled
models used as part of this research will also
serve as a driving problem for model building
and real-time rendering research.
The algorithms and systems developed will also
have a significant impact on computer graphics,
computer-aided design, robotics and physically-based
modeling.
