The STL file format is used for storing 3D models and is a common format for distributing 3D printable models. STL files emerged in the 1980s as a format for storing a 3D mesh as a simple list of triangles. Due to its age and simplistic format, it has gained widespread support within 3D modeling and CAD applications.
As a result of the simple file format and its widespread support amongst 3D editors, the STL format has found itself as the format of choice for the distribution of 3D printable objects. There are many websites that offer 3D printing downloads in the STL format.
Mesh Geometry
As mentioned, STL files make use of a simple structure for containing the 3D mesh data. The 3D model is stored as a continuous list of triangles, with each triangle containing three vertices specifying the location in 3D space of the triangle, which, along with a single vector normal, is all that is required to render the model contained within the STL file. There are two formats of STL files: plain text and binary. When used with large and complex 3D models, the text format leads to very large file sizes and should be avoided, with the binary format offering more efficient storage of the mesh data.
STL Converter Capabilities
As materials containing color information is supported by the STL format, our tool will do its best to include this in the converted file.

A VID file is a video file format native to the ZX Spectrum Next. It stores uncompressed video as a sequence of images along with 8-bit audio. The only currently supported resolution of the video is 320x240 in 256 colors at around 16.6 FPS. For additional technical information, please see the Spectrum Next developer portal.
The VID format supports additional resolutions and framerates, which may or may not include a separate palette per frame. The conversion currently supported is for 320x256 resolution only, with a palette per frame.
