Detailed Description

VSG extension Class for exporting a scene graph to an STL file.

This class exports an Open Inventor scenegraph into an STL format (.stl) file.

ASCII and binary file formats are supported (see setBinaryOutput() method).

Limitations:

  • The STL format does not support color or texture information
    (and this class does not support any of the non-standard extensions for specifying color).
  • The application is responsible for checking if the specified file can be created (see SbFileHelper).

[C++] The STL module must be initialized (see SoSTLFileFormat) before using this class directly.

Member Function Documentation

◆ apply() [1/3]

virtual void SoSTLWriteAction::apply ( const SoPathList pathList,
SbBool  obeysRules = FALSE 
)
virtual

Initiates an action on the graph defined by a list of paths.

TRUE can be passed for the obeysRules flag if the given path list has the following 4 properties:

  1. All paths have the same head node.
  2. Paths are sorted in traversal order.
  3. If one path ends at node A, no other path continues through A.
  4. No two paths are the same.

These rules will be obeyed by path lists returned by picking and by searches for non-group nodes.

Reimplemented from SoAction.

◆ apply() [2/3]

virtual void SoSTLWriteAction::apply ( SoNode node)
virtual

Initiates an action on the graph defined by a node.

Warning: Most actions call ref() on the node before traversing the scene graph, then call unref() after traversal. If the node's reference count was zero (the default), the call to apply() will cause it to be destroyed.

Reimplemented from SoAction.

◆ apply() [3/3]

virtual void SoSTLWriteAction::apply ( SoPath path)
virtual

Initiates an action on the graph defined by a path.

Warning: Most actions call ref() on the path before traversing the scene graph, then call unref() after traversal. If the path's reference count was zero (the default), the call to apply() will cause it to be destroyed.

Reimplemented from SoAction.

◆ getClassTypeId()

static SoType SoSTLWriteAction::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getTypeId()

virtual SoType SoSTLWriteAction::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Reimplemented from SoCallbackAction.

◆ isBinaryOutput()

bool SoSTLWriteAction::isBinaryOutput ( ) const

Returns current state of binary flag.

◆ setBinaryOutput()

void SoSTLWriteAction::setBinaryOutput ( bool  flag)

Sets whether output should be ASCII (default) or binary.

◆ setOutputFileName()

void SoSTLWriteAction::setOutputFileName ( const SbString filename)

Set the output filename to write to.

Parameters
filenamethe output filename to write to.
