Virtual Reality Modeling Language (VRML) Writer Parameters

Version Settings

This parameter indicates which version of VRML to write out.

Selecting VRML 3.3 (X3D) will produce .x3dv files, and selecting VRML 2.0 (VRML97) will produce .wrl files.

Texture Settings

The folder to write texture files. The texture output folder is generally a subfolder of the output dataset, but it can be any path relative to the output dataset. All textures image files for the dataset being produced will be written to this folder.

Texture file names are based on the fme appearance name. Existing old files of the same name from another run or another dataset will be overwritten with new files of the same name.

Specifies the preferred format for associated texture files. This preference will be used as long as the specified format supports the properties of the texture raster; if not, it will be overridden.

Possible values are:

  • Auto (default) – The writer chooses the best representation based on the incoming texture raster.
  • PNG
  • JPEG
  • GIF
  • BMP

If the preferred format is ignored, a message is added to the log file. Possible reasons that the preference will be ignored include a lack of raster palette support, alpha channel support, or color depth support in the selected format.

Coordinate System

Note that the options described below are not available in all formats.

  • Yes: Coordinates of all the points in the written features will be normalized to the interval [-0.5, 0.5] on the largest side of their XYZ-bounding cube. The other dimensions will be scaled proportionally.

Additionally, the transformation matrix required to scale the model back to world coordinates will be written to a companion .fwt file. This can be used to improve precision of the written coordinates. The companion .fwt file will have the same name as the primary data file and will be written in the same folder. For folder-based formats, the file global.fwt will be written instead.

  • No: The original coordinates will be written as provided. Coordinates will not be projected; .fwt world and .prj files will not be generated.
  • Create Projection File Only: A companion .prj file containing the coordinate system and having the same name as the primary data file will be written in the same folder. For folder-based formats, the file global.prj will be written instead. Coordinates will not be projected and a world file will not be generated.
  • Transform Coordinates Only: Transforms the coordinates as in the Yes option, but companion .prj and .fwt world files will not be generated.
