The 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.
|
protected |
Default constructor sets up a cylinder along the Y-axis with height 1.
|
protected |
Constructor taking an explicit cylinder projection definition.
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 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.
|
pure virtual |
Returns rotation on the projection surface which reorients point1 to point2.
Implemented in SbCylinderPlaneProjector, SbCylinderSectionProjector, and SbCylinderSheetProjector.
void SbCylinderProjector::setCylinder | ( | const SbCylinder & | cylinderref | ) |
Set cylinder to project onto.
const SbCylinder & SbCylinderProjector::getCylinder | ( | void | ) | const |
Returns projection cylinder.
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.
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.
Check if point is on the front side or the back side of the cylinder.
Sets the matrix used for converting from the projector's coordinate system to the world coordinate system.
Reimplemented from SbProjector.
|
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.
|
protected |
Flag which says whether or not we should map to the outside or inside of the cylinder surface.
|
protected |
Specification of the projection cylinder.
|
protected |
Which direction the cylindrical surface is oriented.
|
protected |
Set to TRUE
whenever the projection surface needs to be recalculated according to the setting of the SbCylinderProjector::orientToEye flag.
|
protected |
Stores the previously projected 3D point.
