πŸ’– SbSphereProjector(3) πŸ’–

okay bestie, welcome to the Library Functions Manual ✨ this is the page for SbSphereProjector(3), and no cap, it's kind of a big deal β€” it's the abstract base class energy of the whole spherical projector situation. grab a strawberry drink πŸ“ and let's get into it.


✨ NAME ✨

SbSphereProjector β€” the SbSphereProjector class is the abstract base class for mapping to spherical surfaces. πŸ’«

πŸ”₯ Detailed Description πŸ”₯

The SbSphereProjector class is the abstract base class for mapping to spherical surfaces.

The sphere projectors map 2D points to various surface types based on spherical shapes.

See also SbCylinderProjector β€” yeah, its cousin, the cylinder one, go say hi πŸ‘‹


🌟 Constructor & Destructor Documentation 🌟

SbSphereProjector::SbSphereProjector (const SbBool orienttoeye) [protected]

Default constructor sets up a sphere at the origin with radius 1. ⭐ tiny lil unit sphere, she's starting fresh.

SbSphereProjector::SbSphereProjector (const SbSphere & s, const SbBool orienttoeye) [protected]

Constructor taking an explicit sphere projection definition. you bring your own sphere, bestie 🫢


πŸ’… Member Function Documentation πŸ’…

SbVec3f SbSphereProjector::projectAndGetRotation (const SbVec2f & point, SbRotation & rot)

Project the 2D point to a 3D coordinate on the spherical surface, and find the rotation from the last projection to this one. the glow-up from "old point" to "new point", measured in rotation ✨

See also project(), getRotation()

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

Returns rotation on the projection surface which re-orients point1 to point2. it's giving "spin her around, she's a different girl now" πŸ’«

Implemented in SbSpherePlaneProjector, SbSphereSectionProjector, and SbSphereSheetProjector.

void SbSphereProjector::setSphere (const SbSphere & sph)

Set sphere to project onto. 🎯

const SbSphere & SbSphereProjector::getSphere (void ) const

Returns projection sphere.

void SbSphereProjector::setOrientToEye (const SbBool orienttoeye)

Sets whether or not the projection surface should be oriented towards the eye of the viewer. Default is TRUE. πŸ‘οΈ main character energy: always facing the camera.

SbBool SbSphereProjector::isOrientToEye (void ) const

Returns the state of the sphere orientation flag.

void SbSphereProjector::setFront (const SbBool infront)

Set whether to intersect with the outside of the sphere (infront equal to TRUE), or the inside.

SbBool SbSphereProjector::isFront (void ) const

Returns value of the flag which decides whether to intersect with the outside or inside of the sphere.

SbBool SbSphereProjector::isPointInFront (const SbVec3f & point) const

Check if point is on the frontside or the backside of the cylinder. (yes bestie, it says cylinder. we are simply quoting the source, no notes πŸ™ˆ)

void SbSphereProjector::setWorkingSpace (const SbMatrix & space) [virtual]

Sets the matrix used for converting from the projector's coordinate system to the world coordinate system. 🌍 coordinate passport, get her one.

Reimplemented from SbProjector.

SbBool SbSphereProjector::intersectSphereFront (const SbLine & l, SbVec3f & result) [protected]

Intersect line with the SbSphereProjector::sphere and place the intersection point (if any) in result. Considers setFront() settings.

Returns TRUE if line actually hits the sphere, FALSE if it doesn't intersect with it. πŸ”₯ she either ate or she didn't.


πŸŽ€ Member Data Documentation πŸŽ€

SbBool SbSphereProjector::intersectFront [protected]

Flag which says whether or not we should map to the outside or inside of the sphere surface.

SbSphere SbSphereProjector::sphere [protected]

Projection sphere. 🟣

SbBool SbSphereProjector::orientToEye [protected]

Which direction the spherical surface is oriented.

SbBool SbSphereProjector::needSetup [protected]

Set to TRUE whenever the projection surface needs to be recalculated according to the setting of the SbSphereProjector::orientToEye flag. 🚨 girl needs a refresh, respect it.

SbVec3f SbSphereProjector::lastPoint [protected]

Stores the previously projected 3D point. πŸ“Œ the receipts, kept.

okay that's the whole page, you're officially caught up bestie 🫢 go project something gorgeous πŸ’–βœ¨
