SoIndexedLineSet(3)

💖 NAME 💖

Bestie, this is SoIndexedLineSet, from the Coin library (that's the 3 in SoIndexedLineSet(3), iykyk ✨). The SoIndexedLineSet class is used to render and otherwise represent indexed lines. That's the whole vibe. Periodt.

---

🌸 SYNOPSIS 🌸

#include <Invertor/nodes/SoIndexedLineSet.h>

wait no, that's not it — let me not do that to you. It's literally:

#include <Inventor/nodes/SoIndexedLineSet.h>

Inherits SoIndexedShape. So it's got all the indexed-shape lore flowing through it. 🦋

💖 Detailed Description 💖

The SoIndexedLineSet class is used to render and otherwise represent indexed lines. ✨

It's the indexed counterpart of SoLineSet. Lines can be specified using indices for coordinates, normals, materials and texture coordinates.

If no normals are supplied on the stack (or in the vertexProperty field), the lines will be rendered with lighting disabled. So like, no fancy lighting if you don't give it normals, bestie.

For more information about line sets, see documentation in SoLineSet. For more information about indexed shapes, see documentation in SoIndexedShape and SoIndexedFaceSet.

📁 FILE FORMAT/DEFAULTS: 📁

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

🎀 Constructor & Destructor Documentation 🎀

SoIndexedLineSet::SoIndexedLineSet (void )

Constructor. It constructs. You know, standard constructor behavior. 💅

SoIndexedLineSet::~SoIndexedLineSet () [protected], [virtual]

Destructor. It destructs. Protected and virtual, so like, don't call it directly unless you know what you're doing. 💀

🔥 Member Function Documentation 🔥

SoType SoIndexedLineSet::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. So you can get the type ID, bestie. ✨

SoType SoIndexedLineSet::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. So like, it tells you what type you're dealing with, no cap.

Reimplemented from SoIndexedShape.

const SoFieldData ** SoIndexedLineSet::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. So like, you probably don't need to touch this. 🙈

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

const SoFieldData * SoIndexedLineSet::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. So like, it gives you the field data or NULL if there's none. Periodt.

Reimplemented from SoIndexedShape.

void SoIndexedLineSet::initClass (void ) [static]

No description provided in the original. But it's a static method, so there's that. 💅

void SoIndexedLineSet::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. So like, if you're rendering, this gets called. 🔥

Reimplemented from SoShape.

void SoIndexedLineSet::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 SoIndexedLineSet::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 SoIndexedLineSet::notify (SoNotList * l) [protected], [virtual]

Notifies all auditors for this instance when changes are made. So like, it's the gossip girl of the class, telling everyone when something changes. 💅

Reimplemented from SoVertexShape.
