SBCYLINDER(3iv)

💖 SbCylinder — the manual page, but make it make sense 💖

okay so bestie, welcome to the SbCylinder page from the 3IV manual. yes, 3IV. that's the manual section. we're in the Inventor-verse today and it's genuinely so cozy here. grab a strawberry 🍓 and let's get into it.

🌈 NAME 🌈

SbCylinder</purpose> — a whole entire class for representing a cylinder 🥫✨

like. that's it. that's the job. a cylinder. and honestly? iconic.

---

🧬 INHERITS FROM 🧬

SbCylinder

yes bestie. it inherits from SbCylinder. it's giving self-made, self-inherited, main character energy 👑. that's literally what the page says, so that's what I'm telling you. no notes. periodt.

📜 SYNOPSIS 📜

so you wanna use it? you gotta pull in the header first:

#include <Inventor/SbLinear.h>

then here's every single method hanging out in this class, in order, exactly as listed:

                    SbCylinder()
                    SbCylinder(const SbLine &a, float r)
void                setValue(const SbLine &a, float r)
void                setAxis(const SbLine &a)
void                setRadius(float r)
const SbLine &      getAxis() const
float               getRadius() const
SbBool              intersect(const SbLine &l, SbVec3f &intersection)
                         const
SbBool              intersect(const SbLine &l, SbVec3f &enter, SbVec3f
                         &exit) const

look at that little overloaded intersect duo. obsessed. 💅

🦋 DESCRIPTION 🦋

SbCylinder is a simple cylinder datatype. that's the whole vibe. it just... is a cylinder. it defines one. 🧚

and the way that the Inventor toolkit uses it?? for arguments and return values. yes bestie, it's a supporting character that carries the plot. we love a reliable sidekick 🫶

✨ METHODS ✨

the constructors 🎀

• SbCylinder()
• SbCylinder(const SbLine &a, float r)

two constructors, bestie. and here's the thing — one takes an axis and radius. that's the one with the arguments. the other one just shows up with nothing and we respect that too 💀

setValue 🌸

• void setValue(const SbLine &a, float r) — change the axis and the radius. both of them. together. matching set energy 🎀

setAxis / setRadius 💜

• void setAxis(const SbLine &a)
• void setRadius(float r)

set just the axis, or just the radius. pick one, queen, you don't have to do both.

getAxis / getRadius ⭐

• const SbLine & getAxis() const
• float getRadius() const

return the axis and the radius. the classic getter duo. no cap, they just hand you the info.

intersect 🔥

• SbBool intersect(const SbLine &l, SbVec3f &intersection) const
• SbBool intersect(const SbLine &l, SbVec3f &enter, SbVec3f &exit) const

intersect a line and a cylinder, returning TRUE if there is an intersection. that's the whole deal — one overload gives you the single intersection, the other gives you enter and exit like a little arrival-and-departure moment 🦋✨

not me being emotionally invested in a boolean return value. it's TRUE or it's nothing, bestie. high stakes.

👀 SEE ALSO 👀

go read these next, they're all in the same friend group:

• SbVec3f
• SbLine
• SbPlane
• SbSphere
• SoCylinder

that's the whole page, and yes, I read all of it. every option, every signature, every vibe. 💖

so this has been the SbCylinder page, manual section 3IV, and the footer just says SbCylinder(3IV)() — no date, no version, nothing extra, she's mysterious like that 🙈 stay hydrated, go intersect something responsibly, mwah 💅🌈⭐
