Not to be confused with the Wavefront OBJ format, the OBJ8 format is a separate format used in conjunction with the X-Plane 3D simulator software as a means of transferring data between X-Plane and other 3D modeling applications and tools.
The OBJ8 format, as it is known, uses the OBJ file extension and stores 3D model data represented by a list of vertices, triangles, and lines. Other data is included in the format, such as lighting, texture information, and other related data.
OBJ8 files are text-based, with each vertex stored on a single line within the file. The vertex includes its X, Y, and Z position, normal, and texture coordinates. Following the vertices is a list of face indices, which, in the case of a 3D model, represent the triangles that make up the model.
X-Plane Converter Capabilities
Our X-Plane 3D Model/Mesh tool does not support any color material data contained within OBJ files, so the converted file will not contain any color information.
The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modeling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.
STL files come in two flavors: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.
The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.
STL Converter Capabilities
Our 3D conversion tool does not support color or material information in STL files, so your file will not contain any color information.
