💅 SoLinearProfile(3) 💅

okay bestie, so this is the manual page for SoLinearProfile(3) from Coin, and it is long, so we're doing it in parts. Part 1 is right here. Buckle up 🎀

🌸 NAME 🌸

SoLinearProfile — the class that's literally just here to specify linear profile curves. that's it. that's the job. she's straightforward and she knows it ✨

✨ SYNOPSIS ✨

first things first, you gotta pull her in:

#include <Inventor/nodes/SoLinearProfile.h>

and she Inherits SoProfile, so everything SoProfile can do, she can do too. nepotism? no, inheritance. iconic 💅

🌟 Detailed Description 🌟

okay so the whole point: SoLinearProfile is a node for specifying linear profile curves. periodt.

use nodes of this type if you want to set up profiles that are simply straight lines connected by control points. no curves, no drama, just lines doing their little line thing 🫶

FILE FORMAT/DEFAULTS:

LinearProfile {
    index 0
    linkage START_FIRST
}

and that's part 1 bestie, we are NOT done yet — more parts coming 💖

🎀 Constructor & Destructor Documentation 🎀

SoLinearProfile::SoLinearProfile (void )

Bestie, this is the constructor. It does the thing where it makes a brand new SoLinearProfile for you. That's it, that's the whole vibe. ✨

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

And this one is the destructor 💅. It's protected and virtual, so it's lowkey exclusive — you don't just call it yourself, it handles its business when the object's time is up. RIP to your node, iconic while it lasted 🦋.

🔥 Member Function Documentation 🔥

SoType SoLinearProfile::getClassTypeId (void ) [static]

Okay so this static method is the one that hands you back the SoType object that's tied to objects of this class. It's giving "class ID card, but make it runtime" 💖.

SoType SoLinearProfile::getTypeId (void ) const [virtual]

This is the type identification of an object derived from a class inheriting SoBase, and no cap, it's used for runtime type checking and for "downward" casting 👑. So like, when you need to know what something actually is at runtime and then cast it down? That's this. It's doing the detective work fr fr.

Reimplemented from SoProfile.

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

Heads up, bestie: this API member is considered internal to the library, since it's not likely to be of interest to the application programmer. So like… not for you, unless you're deep in the guts. 🙈

It returns the SoFieldData class which holds information about fields in this node. That's the tea.

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

This one gives you back a pointer to the class-wide field data storage object for this instance 🍓. And important detail: if there are no fields present, it returns NULL. So check before you dereference, okay? 😭

Reimplemented from SoProfile.

void SoLinearProfile::getTrimCurve (SoState * state, int32_t & numpoints, float *& points, int & floatspervec, int32_t & numknots, float *& knotvector) [virtual]

Return points and knotvector of the state ✨. It takes SoState * state, then fills in int32_t & numpoints, float *& points, int & floatspervec, int32_t & numknots, and float *& knotvector. All the outputs, all at once, very main character energy.

Implements SoProfile.

void SoLinearProfile::getVertices (SoState * state, int32_t & numvertices, SbVec2f *& vertices) [virtual]

Return vertex set of state 🌈. You hand it SoState * state, and it gives you back int32_t & numvertices and SbVec2f *& vertices. Vertices acquired, slay.

Implements SoProfile.
