  2. AutoCAD DXF - Wikipedia

    en.wikipedia.org/wiki/AutoCAD_DXF

    Contains the data that apply to nongraphical objects, used by AutoLISP, and ObjectARX applications. THUMBNAILIMAGE section Contains the preview image for the DXF file. END OF FILE. The data format of a DXF is called a "tagged data" format, which "means that each data element in the file is preceded by an integer number that is called a group code.

  3. 3D modeling - Wikipedia

    en.wikipedia.org/wiki/3D_modeling

    In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space.

  4. AutoLISP - Wikipedia

    en.wikipedia.org/wiki/AutoLISP

    The user, upon typing 'pointlabel' at the AutoCAD command line, would be prompted to pick a point, either by typing the X and Y coordinates, or clicking a location in the drawing. The function would then place a marker at that point, and create a one-line text object next to it, containing the X and Y coordinates of the point expressed relative ...

  5. 3D computer graphics - Wikipedia

    en.wikipedia.org/wiki/3D_computer_graphics

    The objects in 3D computer graphics are often referred to as 3D models. Unlike the rendered image, a model's data is contained within a graphical data file. A 3D model is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed.

  6. UV mapping - Wikipedia

    en.wikipedia.org/wiki/UV_mapping

    UV texturing is an alternative to projection mapping (e.g., using any pair of the model's X, Y, Z coordinates or any transformation of the position); it only maps into a texture space rather than into the geometric space of the object. The rendering computation uses the UV texture coordinates to determine how to paint the three-dimensional surface.

  9. STL (file format) - Wikipedia

    en.wikipedia.org/wiki/STL_(file_format)

    STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
