Detailed DescriptionThe SbCylinderProjector class is the abstract base class for mapping to cylindrical surfaces. The cylinder projectors map 2D points to various surface types based on cylindrical shapes. See also SbSphereProjector
Constructor & Destructor Documentation
SbCylinderProjector::SbCylinderProjector (const SbBool orienttoeye) [protected]Default constructor sets up a cylinder along the Y axis with height 1.
SbCylinderProjector::SbCylinderProjector (const SbCylinder & cylinder, const SbBool orienttoeye) [protected]Constructor taking an explicit cylinder projection definition.
Member Function Documentation
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. Implements SbProjector. Implemented in SbCylinderSheetProjector, SbCylinderSectionProjector, and SbCylinderPlaneProjector.
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. See also project(), getRotation()
SbRotation SbCylinderProjector::getRotation (const SbVec3f & point1, const SbVec3f & point2) [pure virtual]Returns rotation on the projection surface which re-orients point1 to point2. Implemented in SbCylinderSheetProjector, SbCylinderSectionProjector, and SbCylinderPlaneProjector.
void SbCylinderProjector::setCylinder (const SbCylinder & cylinderref)Set cylinder to project onto.
const SbCylinder & SbCylinderProjector::getCylinder (void) constReturns projection cylinder.
void SbCylinderProjector::setOrientToEye (const SbBool orienttoeye)Sets whether or not the projection surface should be oriented towards the eye of the viewer.
SbBool SbCylinderProjector::isOrientToEye (void) constReturns 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) constReturns value of the flag which decides whether to intersect with the outside or inside of the cylinder.
SbBool SbCylinderProjector::isPointInFront (const SbVec3f & point) constCheck 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.
Member Data Documentation
SbCylinderProjector::intersectFront [protected]Flag which says whether or not we should map to the outside or inside of the cylinder surface.
SbCylinderProjector::cylinder [protected]Specification of the projection cylinder.
SbCylinderProjector::orientToEye [protected]Which direction the cylindrical surface is oriented.
SbCylinderProjector::needSetup [protected]Set to TRUE whenever the projection surface needs to be recalculated according to the setting of the SbCylinderProjector::orientToEye flag.
SbCylinderProjector::lastPoint [protected]Stores the previously projected 3D point.
