The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 [update] SDF format version SDF3 (based on SQLite3 ) uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file.
The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the ...
Well-known binary (WKB) – Binary version of well-known text, used in many spatial databases; SOSI – a spatial data format used for all public exchange of spatial data in Norway; AutoCAD DXF – data transfer format for AutoCAD data (by Autodesk) Geographic Data Files (GDF) — An interchange file format for geographic data
This mismatch was not possible when the census TIGER files were available in ASCII format that was topological unlike shapefiles. The Census Bureau has made the data available through WMS servers. [4] The data forms a base for OpenStreetMap in the US, and also was used for the initial import of US map data into the Waze navigation system.
There is also a binary version of the format, usually with an .X_B extension, which is somewhat more compact. Both .X_T and .X_B are used for parts files. Both .X_T and .X_B are used for parts files. To use Parasolid effectively, software developers need knowledge of CAD in general, computational geometry , and topology .
ObjectARX modules use the file extensions .arx and .dbx instead of the more common .dll. ObjectARX is the most powerful of the various AutoCAD APIs, and the most difficult to master. The typical audience for the ObjectARX SDK includes professional programmers working either as commercial application developers or as in-house developers at ...
The 3DXML file is a zip archive file that contains a BOM file and one or more 3D representation files. Renaming the file from .3dxml to .zip allows a program like WinZip to open the archive. The 3DXML file can contain 3D representation files stored in either XML or binary format and they can contain either surface data, as a mesh that can be ...
These APIs for 3D computer graphics are particularly popular: ANGLE, web browsers graphics engine, a cross-platform translator of OpenGL ES calls to DirectX, OpenGL, or Vulkan API calls. Direct3D (a subset of DirectX) Glide a defunct 3D graphics API developed by 3dfx Interactive. Mantle developed by AMD. Metal developed by Apple.
