SoIndexedShape.3coin2

NAME

SoIndexedShape -

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 it's subclasses.

SYNOPSIS

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 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]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.

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).

References coordIndex, SoMField::getNum(), and SoMFInt32::getValues().

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.

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.

SbBool SoIndexedShape::areTexCoordsIndexed (SoAction * action) [static, protected]Returns whether texture coordinates should be indexed or not.

Takes care of normal cache.

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