FAQ

BRE to CAL Conversion

What are BRE files?

BRE BRE (Breuckmann) is a raw 3D data file format associated with Optocat, a 3D image processing software developed by Breuckmann. This proprietary format contains point clouds, triangulation, and texture data captured via structured light scanners. It is widely used in industrial metrology, art conservation, and reverse engineering. Because of its closed nature and lack of compatibility with modern CAD or 3D modeling programs, BRE files are typically treated as intermediate project files and should be converted to universal formats like STL or OBJ for final distribution and production.

What are CAL files?

A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
