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
Project the 2D point to a 3D coordinate on the cylindrical surface, and find the rotation from the last projection to this one.

- project(), getRotation()
void SbCylinderProjector::setCylinder |
( |
const SbCylinder & |
cylinderref | ) |
|
Set cylinder to project onto.
const SbCylinder & SbCylinderProjector::getCylinder |
( |
void |
| ) |
const |
Returns 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 |
| ) |
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.
