SbCylinderPlaneProjector(3)

💖 SbCylinderPlaneProjector 💖

okay bestie, so this is the manual page for SbCylinderPlaneProjector — that's a section 3 manpage, aka the "C++ library functions" shelf in the Coin docs, so you know it's giving developer realness 🫶. She lives in the Coin library and she is literally the class that projects 2D points to a half-cylinder and a plane. no cap.

🌸 NAME 🌸

SbCylinderPlaneProjector — the class that projects 2D points to a half-cylinder and a plane. periodt. 💅

✨ SYNOPSIS ✨

#include <Inventor/projectors/SbCylinderPlaneProjector.h>

Inherits SbCylinderSectionProjector. so yes she's part of a whole little nepo-baby dynasty of projectors, and she earned it. 👑

🦋 Detailed Description 🦋

The SbCylinderPlaneProjector class projects 2D points to a half-cylinder and a plane. yes bestie, two surfaces, she's versatile like that. 😌

This projector uses a plane along with the half-cylinder of SbCylinderSectionProjector for projections. And here's the little plot twist: if the 2D point mapping "misses" the cylinder section, the 3D point will be projected onto the plane instead. it's giving "backup plan but make it geometry" 💀

🎀 Constructor & Destructor Documentation 🎀

SbCylinderPlaneProjector::SbCylinderPlaneProjector (const float edgetol = 0.9f, const SbBool orienttoeye = TRUE)

Default constructor, the no-argument-basically one. See SbCylinderSectionProjector::SbCylinderSectionProjector(). 🫶

SbCylinderPlaneProjector::SbCylinderPlaneProjector (const SbCylinder & cyl, const float edgetol = 0.9f, const SbBool orienttoeye = TRUE)

Constructor with explicit specification of projection cylinder — so like, you tell her which cylinder to use instead of letting her pick. main character energy fr fr. 🌈

💜 Member Function Documentation 💜

SbProjector * SbCylinderPlaneProjector::copy (void ) const [virtual]

Construct and return a copy of this projector. The caller is responsible for destructing the new instance — so bestie, that returned pointer is yours to clean up, don't just leave it out there. 🫣

⚠️ Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable are using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes. no seriously, "mysterious crashes" is the exact vibe here and it is NOT cute. 💀 handle your CRT, queen.

Reimplemented from SbCylinderSectionProjector.

SbVec3f SbCylinderPlaneProjector::project (const SbVec2f & point) [virtual]

Project the 2D point from normalized viewport coordinates to a 3D point. The mapping will be done in accordance with the type of the projector. iykyk — different projector, different mapping rules. 🔥

Reimplemented from SbCylinderSectionProjector.

SbRotation SbCylinderPlaneProjector::getRotation (const SbVec3f & point1, const SbVec3f & point2) [virtual]

Returns rotation on the projection surface which reorients point1 to point2. spin spin spin ✨

Reimplemented from SbCylinderSectionProjector.

SbRotation SbCylinderPlaneProjector::getRotation (const SbVec3f & point1, const SbBool tol1, const SbVec3f & point2, const SbBool tol2) [protected]

Calculates rotation from point1 to point2, with tol1 and tol2 deciding whether or not to use the tolerance setting. two little yes/no switches for tolerance, very "do we care or do we not" 🌸
