I am attempting to utilize a program such as Presentation 3D so the presenter can interact with the 3d model I have created. The problem seems to be Strata produces an .s3d and I am finding these presentation programs require a .3ds file. I would like to continue to use Stata for my modeling does anyone know of a Presentation program that will work with an .s3d file?
The .s3d format is the native Strata file format. It is not anything like .3ds. You are more likely to find presentation programs the will support a Collada format export out of Strata. The .3ds export out of strata is minimal.
Another route would be to look at the Strata Live 3D program. This program is designed to generate Web and PDF files that can offer 3D object interaction. You can export Strata 3D files to the .xmm format that Live 3D supports.
