📖 Detailed Description

okay so the SoIndexedFaceSet class is the girl for handling generic indexed facesets 💖

Faces get specified through the coordIndex field. Every single face has to be terminated by a negative (-1) index, like closing the door on it 🚪✨ Coordinates, normals, materials and texture coordinates can all be pulled from the current state (or from the vertexProperty node if it's been set), and indexed to build triangles, quads or polygons.

Here's a usage example of just about the simplest possible use of this node, to show a single polygon face:

#Inventor V2.1 ascii

Separator {
   Coordinate3 {
      point [ 0 0 0, 1 0 0, 1 1 0 ]
   }
   IndexedFaceSet {
      coordIndex [ 0, 1, 2, -1 ]
   }
}

Binding PER_VERTEX_INDEXED, PER_VERTEX, PER_FACE_INDEXED, PER_FACE or OVERALL can be set for material, and normals. The default material binding is OVERALL. The default normal binding is PER_VERTEX_INDEXED. When PER_VERTEX_INDEXED binding is used and the corresponding materialIndex, normalIndex, texCoordIndex field is empty, the coordIndex field will be used to index material, normal or texture coordinate. If you do specify indices for material, normals or texture coordinates for PER_VERTEX_INDEXED binding, make sure your index array matches the coordIndex array: there should be a -1 wherever there is a -1 in the coordIndex field. This is done to make this node more easily readable for humans 👀 (yes, for us, the lil guys).

A fairly common request when rendering facesets is how to display a set of faces with different colors on the backside versus the frontside. There is not direct support for this in the API, but it can easily be implemented by duplicating all faces in both the SoShapeHints::COUNTERCLOCKWISE and the SoShapeHints::CLOCKWISE order. Here is a simple usage example, showing the technique for a single polygon, using two SoFaceSet nodes for rendering the same polygon from both sides:

#Inventor V2.1 ascii

Separator {
   Coordinate3 { point [ 0 0 0, 1 0 0, 1 1 0 ] }

   Separator {
      Material { diffuseColor [ 1 1 0 ] }
      ShapeHints {
         vertexOrdering COUNTERCLOCKWISE
         shapeType SOLID
      }
      FaceSet { numVertices [ 3 ] }
   }

   Separator {
      Material { diffuseColor [ 1 0 0 ] }
      ShapeHints {
         vertexOrdering CLOCKWISE
         shapeType SOLID
      }
      FaceSet { numVertices [ 3 ] }
   }
}

The same effect can also be done in the following manner, using an SoIndexedFaceSet to explicitly render the polygon coordinates in both directions (clockwise and counterclockwise):

#Inventor V2.1 ascii

Separator {
   Coordinate3 { point [ 0 0 0, 1 0 0, 1 1 0 ] }

   Material { diffuseColor [ 1 0 0, 1 1 0 ] }
   MaterialBinding { value PER_FACE_INDEXED }

   ShapeHints {
      vertexOrdering COUNTERCLOCKWISE
      shapeType SOLID
   }

   IndexedFaceSet {
      coordIndex [ 0, 1, 2, -1, 2, 1, 0, -1 ]
      materialIndex [ 0, 1 ]
   }
}

Another rather rare issue that might be interesting to know about is that to render polygons with concave borders, you should set up an SoShapeHints node with SoShapeHints::faceType set to SoShapeHints::UNKNOWN_FACE_TYPE in the scene graph before the SoIndexedFaceSet (or SoFaceSet) node. This needs to be done to force the rendering code to tessellate the polygons properly to triangles before sending it off to OpenGL. Without it, the polygons will be sent as-is to OpenGL, and the OpenGL implementation's tessellator is often not able to tessellate properly 🫠 Here is an example which usually fails without the SoShapeHints node (try commenting it out, and see what happens):

#Inventor V2.1 ascii

ShapeHints { faceType UNKNOWN_FACE_TYPE }

Coordinate3
{
        point [ 2 0 0,
                1 0 0,
                1 1 0,
                0 1 0,
                0 2 0,
                1 2 0,
                2 2 0,
                2 1 0 ]
}

FaceSet {}

FILE FORMAT/DEFAULTS:

IndexedFaceSet {
    vertexProperty NULL
    coordIndex 0
    materialIndex -1
    normalIndex -1
    textureCoordIndex -1
}

✨ Member Function Documentation ✨

`SoType SoIndexedFaceSet::getTypeId (void ) const [virtual]`

Okay bestie, this one returns the type identification of an object derived from a class inheriting SoBase. It's giving run-time type checking and "downward" casting energy. 💅

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
  else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
    SoGroup * group = (SoGroup *)node;  // safe downward cast, knows the type
  }
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

**`const SoFieldData * SoIndexedFaceSet::getFieldData (void ) const [protected], [virtual]`**

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. 🫶

Reimplemented from SoIndexedShape.

References SoIndexedFaceSet().

**`void SoIndexedFaceSet::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 SoShape.

References SoIndexedShape::coordIndex, SoShape::finishVertexArray(), SoGLRenderAction::getCacheContext(), SoNode::getNodeType(), SoAction::getState(), SoIndexedShape::getVertexData(), SoState::pop(), SoState::push(), SoVertexShape::readUnlockNormalCache(), SoVertexShape::shouldGLRender(), SoShape::startVertexArray(), SoVertexShape::vertexProperty, and SoNode::VRML1.

**`void SoIndexedFaceSet::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]`**

Action method for the SoGetPrimitiveCountAction. It 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 SoShape.

References SoGetPrimitiveCountAction::addNumTriangles(), SoGetPrimitiveCountAction::canApproximateCount(), SoIndexedShape::coordIndex, and SoShape::shouldPrimitiveCount().

**`SbBool SoIndexedFaceSet::generateDefaultNormals (SoState * state, SoNormalBundle * bundle) [virtual]`**

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

Subclasses should override this method to generate default normals using the SoNormalBundle class. TRUE should be returned if normals were generated, FALSE otherwise.

Default method returns FALSE.

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

Reimplemented from SoVertexShape.

**`SbBool SoIndexedFaceSet::generateDefaultNormals (SoState * state, SoNormalCache * cache) [virtual]`**

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

Subclasses should override this method to generate default normals using the SoNormalCache class. This is more effective than using SoNormalGenerator. Return TRUE if normals were generated, FALSE otherwise.

Default method just returns FALSE.

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

Reimplemented from SoVertexShape.

References SoIndexedShape::coordIndex, and SoNode::VRML1.

**`void SoIndexedFaceSet::generatePrimitives (SoAction * action) [protected], [virtual]`**

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

The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.
