💅 DETAILED DESCRIPTION 💅

Okay bestie, here's the whole vibe: the SoLineSet class is the one that renders and organizes non-indexed polylines. Iconic behavior, honestly.

Polylines get specified using the numVertices field. Coordinates, normals, materials and texture coordinates are all fetched in order from the current state, or from the vertexProperty node if it's set. So like, say numVertices is set to [3, 4, 2] — that means this node would specify a line through coordinates 0, 1 and 2, then a line through coordinates 3, 4, 5 and 6, and finally a single line segment between coordinates 7 and 8. Math girl summer. 📐

Here's a very simple usage example, no notes:

#Inventor V2.1 ascii

Separator {
   Coordinate3 {
      point [ 0 0 0, 1 1 1, 2 1 1, 2 2 1, 2 2 2, 2 2 3, 2 3 2, 2 3 3, 3 3 3 ]
   }

   LineSet {
      numVertices [ 3, 4, 2 ]
   }
}

Binding PER_VERTEX, PER_FACE, PER_PART or OVERALL can be set for material, and normals. The default material binding is OVERALL. The default normal binding is PER_VERTEX. And if no normals are set, the line set will be rendered with lighting disabled. (So if your lines look flat, that's literally why, don't @ me. 😭)

The width of the rendered lines can be controlled through the insertion of an SoDrawStyle node in front of SoLineSet node(s) in the scene graph. Put it in front, bestie, order matters. 💅

FILE FORMAT/DEFAULTS:

LineSet {
    vertexProperty NULL
    startIndex 0
    numVertices -1
}

👑 SoType SoLineSet::getClassTypeId (void ) [static] 👑

This static method returns the SoType object associated with objects of this class. It's giving what even are you energy, but for classes.

🔍 SoType SoLineSet::getTypeId (void ) const [virtual] 🔍

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Reimplemented from SoNonIndexedShape.

🗂️ const SoFieldData ** SoLineSet::getFieldDataPtr (void ) [static], [protected] 🗂️

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

Returns the SoFieldData class which holds information about fields in this node.

📚 const SoFieldData * SoLineSet::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 SoNonIndexedShape.

🛠️ void SoLineSet::initClass (void ) [static] 🛠️

(no description given — it just does its little class-init thing)

🌈 void SoLineSet::GLRender (SoGLRenderAction * action) [virtual] 🌈

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way, or that want to throw geometry primitives at OpenGL, override this method.

Reimplemented from SoShape.

📏 void SoLineSet::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 calculate their bounding box also override this method to change the relevant state variables.

Reimplemented from SoShape.

🔢 void SoLineSet::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 calculate their primitive count also override this method to change the relevant state variables.

Reimplemented from SoShape.

🧬 void SoLineSet::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(). Read it again, bestie. 🙈)

The subclass implementations use 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.

Implements SoShape.

🎁 void SoLineSet::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(). Again, just don't. 😤)

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.

🧸 Member Data Documentation 🧸

🍭 SoMFInt32 SoLineSet::numVertices 🍭

Used to specify polylines. Each entry specifies the number of coordinates in a line. The coordinates are taken in order from the state or from the vertexProperty node.
