Detailed Description

Methods to import and to export scene data and MDL modules.

All import and export methods use a common naming convention to identify files based on URIs as defined in [RFC3986]. Currently only the URI scheme file is supported. An empty URI scheme defaults to the file scheme. URI authorities are not supported, except for the empty URI authority, which is needed in some cases to resolve ambiguities (see below).

Within the file scheme relative and absolute URI paths are supported (see Section 4 in [RFC3986]). URI paths are mapped to filenames as follows:

On Linux and Mac OS, URI paths are treated as filenames paths without any translation.
On Windows, slashes in relative URI paths are replaced by backslashes to obtain the filename.
On Windows, absolute URI paths are mapped to filenames according to the following table.

URI path	Filename	Comment
/C:/dir1/dir2/file	C:\dir1\dir2\file	-
/C/dir1/dir2/file	C:\dir1\dir2\file	This mapping is supported in addition to the first one since a colon is a reserved character in URIs.
/dir1/dir2/file	\dir1\dir2\file	This mapping is only supported for top-level directory names not consisting of a single letter.
//share/dir1/dir2/file	\\share\dir1\dir2\file	This mapping requires an (otherwise optional) empty URI authority (`//`) since otherwise the share name is interpreted as URI authority.

Filenames containing hashes or questions marks are not supported by methods dealing with URIs.

In addition, the following variable can be used in URI paths, which are expanded by the Iray SDK.

"${shader}"
The URI path may start with the string "${shader}" followed by a slash and a relative path, in which case the relative path is resolved relative to the search path for MDL modules. If several directories for MDL modules have been configured, they are searched in turn. This variable is only supported for import methods, not for export methods.

See also: The API components mi::neuraylib::IImport_api and mi::neuraylib::IExport_api offer methods to convert between filenames and URIs. The Iray Programmer's Manual describes "Scene file formats" that the Iray SDK can import.

Enumeration Type Documentation

^◆ Impexp_priority

enum mi::neuraylib::Impexp_priority

Confidence in capabilities of an importer or exporter.

If there is more than one importer or exporter that accepts a certain file format, the importer or exporter with the highest priority is taken. Tie-breaking is unspecified.

See also: mi::neuraylib::IImpexp_base::get_priority()

Enumerator
IMPEXP_PRIORITY_OVERRIDE	The highest priority, reserved for importers and exporters from user plugins.
IMPEXP_PRIORITY_WELL_DEFINED	The highest possible priority for importers or exporters in plugins provided in the Iray SDK. Use only for importers or exporters whose test function cannot fail and whose support for the format is complete.
IMPEXP_PRIORITY_AMBIGUOUS	The test function might fail, or the format might not be fully supported.
IMPEXP_PRIORITY_GUESS	The importer or exporter does not have a good way of detecting the format or the support is very preliminary or incomplete.

Returns a concise single-line clear text description of the importer or exporter.

The description should name, besides maybe a product or brand name, the supported file format and, if applicable, the major file type version or versions that are supported. If a file format differs sufficiently from version to version, you may as well register different importers or exporters for each version.

This description may be used to support user interaction, such as in command-line help or selection boxes of graphical user interfaces. This method must return a valid string. This description is also used in the importer or exporter selection algorithm, which selects among importers and exporters of the same name and same author the one that has the highest version number.

^◆ get_options()

virtual const char * mi::neuraylib::IImport_result::get_options ( ) const

^◆ get_rootgroup()

virtual const char * mi::neuraylib::IImport_result::get_rootgroup ( ) const

pure virtual

Returns the name of the root group.

If the scene file has a scene root (like a render or root statement in a .mi file), the method returns the name of the root element. For most other files, this is the name of a group that was created by the importer and that contains the top-level scene elements. Returns NULL for .mdl files.

^◆ get_supported_extensions()

virtual const char * mi::neuraylib::IImpexp_base::get_supported_extensions ( Uint32 i ) const

pure virtual

Returns the i -th supported file name extension.

Returns: The file name extension including the separating dot, or NULL if i is out of range.

^◆ get_uri()

virtual const char * mi::neuraylib::IImpexp_state::get_uri ( ) const

pure virtual

Returns the unique identifier for the importer or exporter.

You can register only one importer or exporter for a particular UUID. If you wish to support installations with multiple versions of your importer or exporter, you have to change the UUID for each minor and major version number change.

^◆ incr_line_number()

Equivalent to clear_messages(), followed by message_push_back().

Returns

0: Success.
-1: Invalid parameters (NULL pointer).

See also: mi::neuraylib::IExport_result_ext for valid message numbers

^◆ set_message() [4/4]

virtual Sint32 mi::neuraylib::IImport_result_ext::set_message	(	Uint32	number,
		base::Message_severity	severity,
		const char *	message
	)

pure virtual

Replaces all messages by the given message number, severity, and message.

Equivalent to clear_messages(), followed by message_push_back().

Returns

0: Success.
-1: Invalid parameters (NULL pointer).

See also: mi::neuraylib::IImport_result_ext for valid message numbers

^◆ set_options()

virtual Sint32 mi::neuraylib::IImport_result_ext::set_options ( const char * options )

pure virtual

Sets the name of the options.

Returns

0: Success.
-1: Invalid parameters (NULL pointer).

^◆ set_rootgroup()

virtual Sint32 mi::neuraylib::IImport_result_ext::set_rootgroup ( const char * group )

pure virtual

Sets the name of the root group.

Returns

0: Success.
-1: Invalid parameters (NULL pointer).

^◆ test_file_type()

virtual bool mi::neuraylib::IImpexp_base::test_file_type ( const char * extension ) const

pure virtual

Indicates whether a file name extension is supported.

Returns true if the importer or exporter can handle the file type determined by the file name extension. The extension is defined as the part of the file name after and including the first dot, for example, ".mi".

See also: mi::neuraylib::IImporter::test_file_type(), mi::neuraylib::IExporter::test_file_type()
These more specific versions also pass an mi::neuraylib::IReader or mi::neuraylib::IWriter as argument, which can be used to look at lookahead data for magic file headers (readers only) or to decide if the reader or writer capabilities are sufficient to do the import or export (for example, random access capability).

Implemented in mi::neuraylib::IExporter, and mi::neuraylib::IImporter.
