Reader Directives

The suffixes listed are prefixed by the current <ReaderKeyword> in a mapping file. By default, the <ReaderKeyword> for the DirectX reader is DIRECTX.

TEXTURE_DIRECTORIES

This directive specifies the folders that the reader will search to find the texture image files referenced by the VRML files being read.

Required/Optional

Optional

Values

Multiple folders

Default: The folder of the file being read.

Workbench Parameter

Texture Directories

RHCS_CONVERSION

DirectX uses a left-handed coordinate system (LHCS), while FME natively uses a right-handed coordinate system (RHCS).

During import, DirectX features will be transformed to convert to a RHCS according to the option selected on the reader.

Values

  • Flip Z: FME will convert DirectX elements to RHCS by scaling all z-values by negative one (-1).
  • Swap Y and Z: FME will convert DirectX elements to RHCS by swapping the Y and Z axes.

Required/Optional

Optional

Workbench Parameter

Conversion to RHCS Method

SEARCH_ENVELOPE

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that interact with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Mapping File Syntax

<ReaderKeyword>_SEARCH_ENVELOPE <minX> <minY> <maxX> <maxY>

Note: If all four coordinates of the search envelope are specified as zero, the search envelope will be disabled.

Required/Optional

Optional

Workbench Parameter

Minimum X, Minimum Y, Maximum X, Maximum Y

SEARCH_ENVELOPE_COORDINATE_SYSTEM

This directive specifies the coordinate system of the search envelope if it is different than the coordinate system of the data.

The COORDINATE_SYSTEM directive, which specifies the coordinate system associated with the data to be read, must always be set if the SEARCH_ENVELOPE_COORDINATE_SYSTEM directive is set.

If this directive is set, the minimum and maximum points of the search envelope are reprojected from the SEARCH_ENVELOPE_COORDINATE_SYSTEM to the reader COORDINATE_SYSTEM prior to applying the envelope.

Required/Optional

Optional

Mapping File Syntax

<ReaderKeyword>_SEARCH_ENVELOPE_COORDINATE_SYSTEM <coordinate system>

Workbench Parameter

Search Envelope Coordinate System

CLIP_TO_ENVELOPE

This directive specifies whether or not FME should clip features to the envelope specified in the SEARCH_ENVELOPE directive.

Values

YES | NO (default)

Mapping File Syntax

<ReaderKeyword>_CLIP_TO_ENVELOPE [yes | no]

Workbench Parameter

Clip To Envelope
