# writers.fbx

Output to the Autodesk FBX format. The pipeline requires the mesh to be built, as only mesh output is created. You must us filters.poisson or filters.greedyprojection to compute a mesh for the point cloud before outputting the FBX.

Dynamic Plugin

This stage requires a dynamic plugin to operate

## Compilation

You must download and install the Autodesk SDK and then compile the PDAL FBX plugin against it. Visit https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2019-0 to obtain a current copy of the SDK.

Example Windows CMake configuration

## Options

filename

  FBX filename to write [Required]

ascii

  Write ASCII FBX format. [Default: false]

where

  An expression that limits points passed to a writer. Points that don’t pass the expression skip the stage but are available to subsequent stages in a pipeline. [Default: no filtering]

where_merge

  A strategy for merging points skipped by a ‘where’ option when running in standard mode. If `true`, the skipped points are added to the first point view returned by the skipped filter. If `false`, skipped points are placed in their own point view. If `auto`, skipped points are merged into the returned point view provided that only one point view is returned and it has the same point count as it did when the writer was run. [Default: `auto`]
