Detailed Description

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

This class contains four fields for storing indices to coordinates, normals, materials and texture coordinates. It also has some convenience methods which can be used by it's subclasses.

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]
 

For internal use only.

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 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.

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.

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.

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.

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