FAQ
CALS to OBJ Conversion
What are CALS files?
The CALS image format includes a compressed raster/bitmap file. Though considered rare by mainstream users, CALS files are used by many document-handling, DTP and image processing applications employed by the US government. The format itself was created by the Department of Defense as a standard for storing an interchanging graphics data. CALS stands for "Computer Aided Acquisitions and Logistics Support", which is an office inside the Department of Defense.
What are OBJ files?
OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
