Member Enumeration Documentation

enum SoShape::TriangleShapeThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Constructor & Destructor Documentation

SoShape::SoShape (void) [protected]Constructor.

SoShape::~SoShape () [protected, virtual]Destructor.

Member Function Documentation

void SoShape::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 SoNode.

Reimplemented in SoAsciiText, SoCone, SoCube, SoCylinder, SoFaceSet, SoImage, SoIndexedFaceSet, SoIndexedLineSet, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoIndexedShape, SoIndexedTriangleStripSet, SoLineSet, SoMarkerSet, SoNonIndexedShape, SoNurbsCurve, SoNurbsSurface, SoPointSet, SoQuadMesh, SoSphere, SoText2, SoText3, SoTriangleStripSet, and SoVertexShape.

SbBool SoShape::affectsState (void) const [virtual]Returns TRUE if the node could have any effect on the state during traversal.

If it returns FALSE, no data in the traversal-state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.

The default method returns TRUE, on a 'better safe than sorry' philosophy.

Reimplemented from SoNode.

void SoShape::notify (SoNotList * l) [virtual]Notifies all auditors for this instance when changes are made.

Reimplemented from SoNode.

Reimplemented in SoAsciiText, SoImage, SoText3, and SoVertexShape.

References SoNode::notify().

Referenced by SoVertexShape::notify(), SoText3::notify(), SoImage::notify(), and SoAsciiText::notify().

void SoShape::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]Action method for the SoGetBoundingBoxAction.

Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.

Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

Reimplemented in SoIndexedLineSet, SoIndexedNurbsCurve, SoLineSet, SoNurbsCurve, and SoPointSet.

References SoGetBoundingBoxAction::extendBy(), SbBox3f::isEmpty(), and SoGetBoundingBoxAction::setCenter().

Referenced by SoPointSet::getBoundingBox(), SoNurbsCurve::getBoundingBox(), SoLineSet::getBoundingBox(), SoIndexedNurbsCurve::getBoundingBox(), and SoIndexedLineSet::getBoundingBox().

void SoShape::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoNode.

Reimplemented in SoAsciiText, SoCone, SoCube, SoCylinder, SoFaceSet, SoImage, SoIndexedFaceSet, SoIndexedLineSet, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoIndexedTriangleStripSet, SoLineSet, SoMarkerSet, SoNurbsCurve, SoNurbsSurface, SoPointSet, SoQuadMesh, SoSphere, SoText2, SoText3, and SoTriangleStripSet.

References SoVertexProperty::doAction(), generatePrimitives(), SoNode::getClassTypeId(), SoAction::getState(), SoBase::isOfType(), SoState::pop(), SoState::push(), and shouldGLRender().

void SoShape::rayPick (SoRayPickAction * action) [virtual]Calculates picked point based on primitives generated by subclasses.

Reimplemented from SoNode.

Reimplemented in SoCone, SoCube, SoCylinder, SoImage, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoNurbsCurve, SoNurbsSurface, SoSphere, and SoText2.

References computeObjectSpaceRay(), generatePrimitives(), SoAction::getState(), and shouldRayPick().

void SoShape::callback (SoCallbackAction * action) [virtual]Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

References generatePrimitives(), and SoCallbackAction::shouldGeneratePrimitives().

void SoShape::computeBBox (SoAction * action, SbBox3f & box, SbVec3f & center) [pure 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.

Implemented in SoAsciiText, SoCone, SoCube, SoCylinder, SoFaceSet, SoImage, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoIndexedShape, SoLineSet, SoNurbsCurve, SoNurbsSurface, SoPointSet, SoQuadMesh, SoSphere, SoText2, SoText3, and SoTriangleStripSet.

void SoShape::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

Reimplemented in SoAsciiText, SoCone, SoCube, SoCylinder, SoFaceSet, SoImage, SoIndexedFaceSet, SoIndexedLineSet, SoIndexedNurbsCurve, SoIndexedNurbsSurface, SoIndexedTriangleStripSet, SoLineSet, SoMarkerSet, SoNurbsCurve, SoNurbsSurface, SoPointSet, SoQuadMesh, SoSphere, SoText2, SoText3, and SoTriangleStripSet.

Referenced by SoLevelOfDetail::doAction(), and getComplexityValue().

float SoShape::getDecimatedComplexity (SoState * state, float complexity) [static]Not implemented in Coin. Should probably have been private in TGS Inventor API.

const SoBoundingBoxCache * SoShape::getBoundingBoxCache (void) constReturn the bounding box cache for this shape. It might return NULL if no bounding box cache has been created. If not NULL, the caller must check if the cache is valid before using it. This can be done using SoCache::isValid().

This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

This method returns NULL in Open Inventor, and subclasses will need to override this method to create details for a SoPickedPoint.

This is not necessary with Coin. Of course, if you choose to override it, it will work in the same way as Open Inventor.

For this to work, you must supply a face or line detail when generating primitives. If you supply NULL for the detail argument in SoShape::beginShape(), you'll have to override this method.

void SoShape::beginShape (SoAction *const action, const TriangleShape shapetype, SoDetail *const detail = NULL) [protected]This method is used to generate primitives for a shape. It's typically called from a node's generatePrimitives() method. If you have your own shape and want to write a generatePrimitives() method for that shape, it's probably a good idea to take a peek in the generatePrimitives() method for a similar shape in Coin.

generatePrimitives() can contain several beginShape()/endShape() sequences. shapeVertex() is used for each vertex between beginShape() and endShape(). For instance, to generate primitives for a triangle you'd do something like this:

 
   SoPrimitiveVertex vertex;
 
   this->beginShape(action, SoShape::POLYGON);
   vertex.setPoint(SbVec3f(0.0f, 0.0f, 0.0f));
   this->shapeVertex(&vertex);
   vertex.setPoint(SbVec3f(1.0f, 0.0f, 0.0f));
   this->shapeVertex(&vertex);
   vertex.setPoint(SbVec3f(1.0f, 1.0f, 0.0f));
   this->shapeVertex(&vertex);
   this->endShape();
   .fi
 
 
 Note that the SoPrimitiveVertex instance can simply be placed on the stack and not allocated. SoShape will copy the needed information when you call shapeVertex().
 
 Before calling shapeVertex(), you can set extra information for the SoPrimitiveVertex, including normal, material index, and texture coordinates.
 
 This method is slightly different from its counterpart from the original Open Inventor library, as this method has an SoDetail as the last argument, and not an SoFaceDetail. This is because we accept more TriangleShape types, and the detail might be a SoFaceDetail or a SoLineDetail. There is no use sending in a SoPointDetail, as nothing will be done with it.
