🌈 Detailed Description 🌈

The SbCylinderProjector class is the abstract base class for mapping to cylindrical surfaces. she's the blueprint, not the final boss πŸ’…

The cylinder projectors map 2D points to various surface types based on cylindrical shapes. that's literally the whole vibe check.

🧚 Constructor & Destructor Documentation 🧚

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

Default constructor, and it sets up a cylinder along the Y axis with height 1. iconic starting position fr fr ✨

SbCylinderProjector::SbCylinderProjector (const SbCylinder & cylinder, const SbBool orienttoeye) [protected]

Constructor taking an explicit cylinder projection definition. you bring your own cylinder, she brings the projection πŸŽ€


πŸ‘‘ Member Function Documentation πŸ‘‘

virtual SbVec3f SbCylinderProjector::project (const SbVec2f & point) [pure 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. no cap, that's the whole job.

Implements SbProjector.

Implemented in SbCylinderPlaneProjector, SbCylinderSectionProjector, and SbCylinderSheetProjector.

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

Project the 2D point to a 3D coordinate on the cylindrical surface, and find the rotation from the last projection to this one. two birds, one glamorous stone πŸ¦‹

  • project(), getRotation()

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

Returns rotation on the projection surface which re-orients point1 to point2. like a glow-up for points.

Implemented in SbCylinderPlaneProjector, SbCylinderSectionProjector, and SbCylinderSheetProjector.

void SbCylinderProjector::setCylinder (const SbCylinder & cylinderref)

Set cylinder to project onto. that's the one, bestie.

const SbCylinder & SbCylinderProjector::getCylinder (void ) const

Returns projection cylinder. she's right there πŸ’–

void SbCylinderProjector::setOrientToEye (const SbBool orienttoeye)

Sets whether or not the projection surface should be oriented towards the eye of the viewer. main character energy for the surface, honestly.

SbBool SbCylinderProjector::isOrientToEye (void ) const

Returns the state of the cylinder orientation flag.

void SbCylinderProjector::setFront (const SbBool infront)

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

SbBool SbCylinderProjector::isFront (void ) const

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

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

Check if point is on the frontside or the backside of the cylinder.

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

Sets the matrix used for converting from the projector's coordinate system to the world coordinate system.

Reimplemented from SbProjector.

SbBool SbCylinderProjector::intersectCylinderFront (const SbLine & line, SbVec3f & result) [protected]

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

Returns TRUE if line actually hits the cylinder, FALSE if it doesn't intersect with it. πŸ’€ either she hits or she doesn't.


πŸ“ Member Data Documentation πŸ“

SbBool SbCylinderProjector::intersectFront [protected]

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

SbCylinder SbCylinderProjector::cylinder [protected]

Specification of the projection cylinder. the blueprint of the blueprint πŸ’…

SbBool SbCylinderProjector::orientToEye [protected]

Which direction the cylindrical surface is oriented.

SbBool SbCylinderProjector::needSetup [protected]

Set to TRUE whenever the projection surface needs to be recalculated according to the setting of the SbCylinderProjector::orientToEye flag. she's got a lil "recalculate me" sticky note on her forehead.

SbVec3f SbCylinderProjector::lastPoint [protected]

Stores the previously projected 3D point. the memory of the last serve, lowkey.
