Microsoft DirectX Reader Parameters

This parameter specifies the folders from which the reader will search to find the texture image files referenced by the DirectX files being read.

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.

• 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.

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 intersect with the bounding box are returned.

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

Select this parameter to remove any portions of exported features outside the area of interest.

The illustration below shows the results of the Search Envelope when Clip to Search Envelope is set to No on the left side and Yes on the right side.

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is set to Yes, a clip is also performed in addition to the intersection.
