🎀 DESCRIPTION

So. It's a 2D box 📦 with planes parallel to the major axes, and you define it with two points — both specified as floating point — sitting on a diagonal. That's it, that's the whole vibe.

She's part of the standard Inventor datatype classes, and she gets used as input and output to geometry operations. Lowkey essential, highkey underrated 💅

💅 METHODS

🫶 constructors + destructor

                     SbBox2f()
                     SbBox2f(float xmin, float ymin, float xmax float ymax)
                     SbBox2f(const SbVec2f &min, const SbVec2f &max)
 void                ~SbBox2f()

Constructors and destructor for a 2D float box, periodt. xmin, ymin, xmax, and ymax are the bounds of the box. And min and max? Those are the corners of the diagonal that define the box 🦋

🔍 getMin() + getMax()

 const SbVec2f &     getMin()
 const SbVec2f &     getMax()

Returns the minimum and maximum points of the box. Short, sweet, slay 💖

🎯 getCenter()

 SbVec2f             getCenter()

Returns the center of the box. Right in the middle, where she belongs ✨

🌱 extendBy()

 void                extendBy(const SbVec2f &point)
 void                extendBy(const SbBox2f &box)

Extends this box — only if necessary, bestie — so it contains the specified point or other box. Growth mindset 🌸

💥 intersect()

 SbBool              intersect(const SbVec2f &point)
 SbBool              intersect(const SbBox2f &box)

Returns TRUE if the specified point or box intersects this box. Otherwise it's giving nothing and you get FALSE 🫶

📐 setBounds()

 void                setBounds(float xmin, float ymin, float xmax, float
                          ymax)
 void                setBounds(const SbVec2f &min, const SbVec2f &max)

Sets the corners of the box. Two ways to do it, pick your fighter 💅

📏 getBounds()

 void                getBounds(float &xmin, float &ymin, float &xmax, float
                          &ymax)
 void                getBounds(SbVec2f &min, SbVec2f &max)

Gets the corners of the box. Same energy, opposite direction 🔁

🌟 getOrigin()

 void                getOrigin(float &x0, float &y0)

Gets box origin. Where it all began 🥹

📦 getSize()

 void                getSize(float &x, float &y)

Gets box size. How much box, exactly 🎀

🦋 getAspectRatio()

 float               getAspectRatio()

Gets box aspect ratio. The proportions, the lewk 🌈

🧹 makeEmpty()

 void                makeEmpty()

Makes an empty box. Decluttering era 🧚

🕳️ isEmpty()

 SbBool              isEmpty()

Returns TRUE if the box is empty, and FALSE otherwise. No in-between 💀

📊 hasArea()

 SbBool              hasArea()

Returns TRUE if both dimensions of the box have positive size, and FALSE otherwise. Both of them. Not one. Both 👑
