Detailed Description

The SoIndexedShape class is the superclass for all indexed vertex shapes.

This is an abstract class which contains storage for four fields for indices to coordinates, normals, materials and texture coordinates for its subclasses.

Constructor & Destructor Documentation

◆ SoIndexedShape()

SoIndexedShape::SoIndexedShape ( void )
protected

Constructor.

◆ ~SoIndexedShape()

SoIndexedShape::~SoIndexedShape ( )
protectedvirtual

Destructor.

Member Function Documentation

◆ areTexCoordsIndexed()

SbBool SoIndexedShape::areTexCoordsIndexed ( SoAction * action)
staticprotected

Returns whether texture coordinates should be indexed or not.

See also
SoTextureCoordinateBinding

◆ computeBBox()

void SoIndexedShape::computeBBox ( SoAction * action,
SbBox3f & box,
SbVec3f & center )
protectedvirtual

Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.

◆ getClassTypeId()

SoType SoIndexedShape::getClassTypeId ( void )
static

This static method returns the SoType object associated with objects of this class.

◆ getColorIndices()

const int32_t * SoIndexedShape::getColorIndices ( void )
protected

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

◆ getFieldData()

const SoFieldData * SoIndexedShape::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 SoVertexShape.

Reimplemented in SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, and SoIndexedTriangleStripSet.

◆ getFieldDataPtr()

const SoFieldData ** SoIndexedShape::getFieldDataPtr ( void )
staticprotected

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the SoFieldData class which holds information about fields in this node.

◆ getNormalIndices()

const int32_t * SoIndexedShape::getNormalIndices ( void )
protected

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

◆ getNumVerts()

int SoIndexedShape::getNumVerts ( const int startCoord)
protected

Starting at index position startCoord, returns the number of indices until either the end of index array or a separator index (-1).

◆ getTexCoordIndices()

const int32_t * SoIndexedShape::getTexCoordIndices ( void )
protected

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.

◆ getTypeId()

SoType SoIndexedShape::getTypeId ( void ) const
virtual

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

Reimplemented from SoVertexShape.

Reimplemented in SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, and SoIndexedTriangleStripSet.

◆ getVertexData()

SbBool SoIndexedShape::getVertexData ( SoState * state,
const SoCoordinateElement *& coords,
const SbVec3f *& normals,
const int32_t *& cindices,
const int32_t *& nindices,
const int32_t *& tindices,
const int32_t *& mindices,
int & numcindices,
const SbBool needNormals,
SbBool & normalCacheUsed )
protected

Convenience method that will fetch data needed for rendering or generating primitives. Takes care of normal cache.

This method was not part of the original SGI Open Inventor API, and is an extension specific for Coin.

◆ initClass()

void SoIndexedShape::initClass ( void )
static

◆ setupIndices()

void SoIndexedShape::setupIndices ( const int numParts,
const int numFaces,
const SbBool needNormals,
const SbBool needTexCoords )
protected

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private.

Let us know if you need this method for any code you are porting and we'll look into implement it properly.
