Generally Open Inventor classes that need to open a named file will search for the file in each of these directories in order. maintains a list of directories (initially empty). When EOF is reached, the stack is popped. When reading, skips over Open Inventor comments (from '#' to end of line) and can stack input files. See class for more information about defining and loading new readersįor Open Inventor format files, users can also register additional valid file headers. Input readers are defined as new classes inheriting from the class. can also be extended with custom file format readers.

These formats also require redistributing the corresponding plugin library (fei_inventor_io_cad) with the application. See .CAD.SoCADInputReader for the current list. Open Inventor also supports many standard CAD file formats. These formats require redistributing the corresponding plugin library with the application.ĭXF : fei_inventor_io_dxf (e.g. X3D Classic VRML format (.x3dv) See VRML_LIMITATIONS for details.Īdditional input readers are provided as plugins for: In fact the initial bytes of the file are checked when the file is opened to automatically determine if it is compressed or not. The file extension 'ivz' is recognized for compressed Open Inventor files, but is not mandatory. Since Open Inventor 8.1, both the ASCII and binary formats can be compressed using the gz format (e.g. supports ASCII (default) and binary Open Inventor formats.

To check if a file exists, get file properties, etc see. Calling (), or methods like () and (), with a default object will make the application appear to "hang" because it is waiting for data on standard input. If the call fails, the object itself is still valid and remains in the default state. NOTE: Applications should always check the result of calling the (System.String, System.Boolean, System.Boolean) method. There is an example code fragment on the page. is typically used with (, or () to load data and create a scene graph.

can report progress during the input operation (see updateReadPercent). can search for a file in a list of directories (see addDirectoryFirst etc). The input source can be the standard input stream (default), a file (see openFile) or a buffer in memory (see setBuffer). This class is used by the reading routines when reading Open Inventor (.iv) format data or various geometry data formats that can be converted into an Open Inventor scene graph.
