A Systematic Approach to Evaluate Three Dimensional File Compatibility and Conversion Tools in Virtual Environments



As part of my for ESM4714 Scientific Visualization and Multimedia, I wanted to explore the correct techniques of bringing 3D-studio files into the CAVE, a 10x10 virtual reality projection system located at the VT-CAVE in Blacksburg Va.

The reason I chose to evaluate the conversion process of bringing 3D-studio models into the CAVE was because this is a modeling package that is being widely used in the animation and architectural profession. The problem that has been run into at bringing models into the CAVE via 3D-studio is the problem of the available conversion programs for the CAVE. The one that is widely used when bringing models into the CAVE is the 3dsToIv. The problem with this converter is that it does not support the UVW mapping that 3d-Studio produces. So textures in the model are stretched across the surface. The textures on a model are the most important attribute to creating a realistic effect. The other problem in using the stabndard converter for translating lighting attributes is that the lights are lost in the translation. All these issues and the proper way for developing a model for the CAVE is part of my project for this semester.

The following area's are examined in my Project. I will look into Model Development techniques for VE's, Texture Conversion, Light attributes.
