FAQ
CAL to OBJ Conversion
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.
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.
