splines(3U)

💖 NAME 💖

OpenBSpline, S_OpenBSpline, F_OpenBSpline, SF_OpenBSpline, SFH_OpenBSpline, ClosedBSpline, S_ClosedBSpline, F_ClosedBSpline, SF_ClosedBSpline, SFH_ClosedBSpline — structured graphics classes for open and closed B-splines

okay so bestie, this is splines(3U) from the InterViews Reference Manual, and it's literally your one-stop shop for B-spline structured graphics, both the open kind and the closed kind. no cap. 🎀

✨ SYNOPSIS ✨

#include <Unidraw/Graphic/splines.h>

🌸 DESCRIPTION 🌸

So here's the tea 🍓: OpenBSpline and ClosedBSpline are Vertices subclasses, and they're abstract base classes — like, they exist to be the blueprint, not to be instantiated directly, iykyk. One is for open B-splines, one is for closed B-splines.

The predefined subclasses you actually get to play with:

• S_OpenBSpline, F_OpenBSpline, and SF_OpenBSpline — these draw stroked, filled, and stroked-filled open B-splines, respectively.
• S_ClosedBSpline, F_ClosedBSpline, and SF_ClosedBSpline — these draw stroked, filled, and stroked-filled closed B-splines, respectively.

Then we have the extra-special ones 👑: SFH_OpenBSpline and SFH_ClosedBSpline are identical to their SF_-prefixed counterparts, EXCEPT — and this is the part that eats 💅 — they can detect hits on their control points in addition to detecting hits on their visible parts. main character energy fr fr.

And the storage situation, because everything has a home 🫶:

• the stroked subclasses store a PSBrush
• the filled subclasses store a PSPattern
• the stroked-filled subclasses store one of each

🦋 OPENBSPLINE PROTECTED OPERATIONS 🦋

• OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil) — OpenBSpline's constructor is protected, and that's on purpose, bestie: it's there to prevent instantiation of the abstract base class. The parameters get passed directly to the Vertices constructor. so don't try to make one, it's not for you 🙈

💅 OPENBSPLINE SUBCLASS PUBLIC OPERATIONS 💅

• S_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• F_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• SF_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• SFH_OpenBSpline(Coord* x, Coord* y, int count, Graphic* = nil)

These are the constructors for the various predefined Rect subclasses. (yes, it says Rect, that's what the page says, we're just the messenger 💀)

🎀 CLOSEDBSPLINE PROTECTED OPERATIONS 🎀

• ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil) — same deal as its open sibling: the constructor is protected to prevent instantiation of the abstract base class, and the parameters are passed directly to the Vertices constructor. no touching, it's abstract ✋

⭐ CLOSEDBSPLINE SUBCLASS PUBLIC OPERATIONS ⭐

• S_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• F_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• SF_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)
• SFH_ClosedBSpline(Coord* x, Coord* y, int count, Graphic* = nil)

Constructors for the various predefined Rect subclasses. (again with the Rect, we know, we know 😭)

okay that's the whole page, periodt ✨ this one came from Unidraw and it's dated 2 February 1991 — vintage, retro, ahead of its time, we love a classic 🌈🦋 bye bestie, go draw some splines 💖
