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.
Since:
Coin 3.0

SoSTLFileKit::SoSTLFileKit (void) Constructor.
SoSTLFileKit::~SoSTLFileKit (void) [protected, virtual] Destructor.
Member Function Documentation
static void SoSTLFileKit::initClass (void) [static] Sets up initialization
for data common to all instances of this class, like submitting
necessary information to the Coin type system.
Reimplemented from SoForeignFileKit.
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.

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.
