## Detailed Description

SoSTLFileKit is a class for using STL files with Coin.

Class for using STL files with Coin. You can use it to read and write STL files, and convert back and forth between Open Inventor scene graphs and SoSTLFileKits.

STL files are 3D models intended for 3D printers, and is a format supported by a wide variety of computer-aided design programs. STL models are, because of their intended purpose, always representations of solid objects. STL is short for Stereolithography, the process used for 3D printing.

Ordinary STL models do not contain color information. There are, however, two extensions to the binary file format for specifying color. Currently neither extension is supported. This is caused by lack of sample models using the extensions and will be added as soon as such models are found. We have the specs on the extensions, and it should be pretty straight-forwards to implement, but we want to get it right at once since we have write support (we don't want to inadvertently create a third color extension ;).

When writing STL files, certain STL model criterias are not enforced by SoSTLFileKit. These are:

- STL models should represent complete solids - it is the user's responsibility to give models of solid data to readScene(), and not readScene()'s responsibility to check the incoming data.
- STL models should have all triangles in counterclockwise order. This is not enforced either.
- STL models should reside in the positive octant of the coordinate space. This is also the user's responsibility to ensure, although adding functionality for translating the model should be easy, so it might get implemented.

Since the color extensions are not supported yet, color information is not collected either when converting Open Inventor scene graphs to SoSTLFileKits.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

  Coin 3.0

## Member Function Documentation

SoType SoSTLFileKit::getTypeId | ( | void |  | ) | const
| virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoForeignFileKit.

const SoFieldData * SoSTLFileKit::getFieldData | ( | void |  | ) | const
| protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns `NULL`.

Reimplemented from SoForeignFileKit.

const SoNodekitCatalog * SoSTLFileKit::getNodekitCatalog | ( | void |  | ) | const
| virtual

Returns the nodekit catalog which defines the layout of this class' kit.

Reimplemented from SoForeignFileKit.

void SoSTLFileKit::initClass | ( | void |  | ) |
| static

Initializes class and registers file identification functions.

SbBool SoSTLFileKit::identify | ( | const char * | filename | ) |
| static

Returns wether or not filename is identified as an STL file.

SbBool SoSTLFileKit::readFile | ( | const char * | filename | ) |
| virtual

Reads in an STL file. Both ascii and binary files are supported. For binary files, the color extensions are not implemented yet.

Returns FALSE if filename could not be opened or parsed correctly.

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::readScene | ( | SoNode * | scene | ) |
| virtual

Converts a scene graph into an SoSTLFileKit. Useful for creating STL files.

See also
  canReadScene, canWriteFile, writeFile

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::writeFile | ( | const char * | filename | ) |
| virtual

Writes the STL model to an STL file.

  binary, info, canWriteFile, canReadScene

Reimplemented from SoForeignFileKit.

SbBool SoSTLFileKit::writeScene | ( | SoNode *& | root,
|  | const char * | format = `NULL`
| ) |  |
| virtual

Converts the STL model into a native scene graph.

See also
  canWriteScene

Reimplemented from SoForeignFileKit.

void SoSTLFileKit::reset | ( | void |  | ) |
| protected

Resets the STL model so it contains nothing.

SbBool SoSTLFileKit::addFacet | ( | const SbVec3f & | v1,
|  | const SbVec3f & | v2,
|  | const SbVec3f & | v3,
|  | const SbVec3f & | n
| ) |  |
| protected

Adds one triangle to the STL model.

See also
  reset, organizeModel

void SoSTLFileKit::organizeModel | ( | void |  | ) |
| protected

Should be called after the STL model is completely set up in the SoSTLFileKit through import from a file or from a scene graph. The model will then be optimized for fast rendering.
