Detailed Description

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

It holds four field for storing indices to coordinates, normals, materials and texture coordinates, and also has some convenience methods which can be used by subclasses.


Constructor & Destructor Documentation

SoIndexedShape::SoIndexedShape void    [protected]
 

Constructor.

SoIndexedShape::~SoIndexedShape   [protected, virtual]
 

Destructor.


Member Function Documentation

void SoIndexedShape::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 SoVertexShape.

Reimplemented in SoIndexedFaceSet, SoIndexedLineSet, and SoIndexedTriangleStripSet.

void SoIndexedShape::computeBBox SoAction   action,
SbBox3f   box,
SbVec3f   center
[protected, virtual]
 

Overloaded to calculate bounding box of all indexed coordinates, using the coordIndex field.

Reimplemented from SoShape.

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).

void SoIndexedShape::setupIndices const int    numParts,
const int    numFaces,
const SbBool    needNormals,
const SbBool    needTexCoords
[protected]
 

Not implemented. Probably only used internally in OIV. Let us know if you need this method and we'll implement it.

const int32_t * SoIndexedShape::getNormalIndices void    [protected]
 

Not implemented. Probably only used internally in OIV. Let us know if you need this method and we'll implement it.

const int32_t * SoIndexedShape::getColorIndices void    [protected]
 

Not implemented. Probably only used internally in OIV. Let us know if you need this method and we'll implement it.

const int32_t * SoIndexedShape::getTexCoordIndices void    [protected]
 

Not implemented. Probably only used internally in OIV. Let us know if you need this method and we'll implement it.

SbBool SoIndexedShape::areTexCoordsIndexed SoAction   action [static, protected]
 

Returns whether texture coordinates should be indexed or not.

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 is not part of the OIV API.
