NAME¶
SbCylinder - The SbCylinder class is a representation of a cylinder. This class is used within other classes in Coin. It contains data to represent a cylinder by an axis and a radius. The cylinder has no length/height value, which means it is treated as of infinite length.SYNOPSIS¶
Public Member Functions¶
SbCylinder (void)
Detailed Description¶
The SbCylinder class is a representation of a cylinder. This class is used within other classes in Coin. It contains data to represent a cylinder by an axis and a radius. The cylinder has no length/height value, which means it is treated as of infinite length. See also:SbLine, SbSphere
Constructor & Destructor Documentation¶
SbCylinder::SbCylinder (void)¶
The default constructor will make a cylinder of radius 1, center axis going through origo in the parallel direction of the positive y-axis.SbCylinder::SbCylinder (const SbLine &a, const floatr)¶
Construct and initialize an SbCylinder instance with the given axis a and radius r.Member Function Documentation¶
void SbCylinder::setValue (const SbLine &a, const floatr)¶
Set the axis and radius of the cylinder. See also:getAxis(), getRadius().
void SbCylinder::setAxis (const SbLine &a)¶
Set the center axis of the cylinder. See also:setRadius(), getAxis().
void SbCylinder::setRadius (const floatr)¶
Set the radius of the cylinder. See also:setAxis(), getRadius().
const SbLine & SbCylinder::getAxis (void) const¶
Return the line which is the center axis of the cylinder. See also:setAxis(), getRadius().
float SbCylinder::getRadius (void) const¶
Return radius of cylinder. See also:setRadius(), getAxis().
SbBool SbCylinder::intersect (const SbLine &l, SbVec3f &intersection) const¶
Finds the intersection point of the ray l on the cylinder where the ray enters, and return this point in intersection. If the ray does not intersect the cylinder, FALSE is returned, otherwise we will return TRUE.SbBool SbCylinder::intersect (const SbLine &l, SbVec3f &enter, SbVec3f &exit) const¶
Find the intersection points of the ray l on the cylinder and return these in enter and exit. If the ray just 'grazes' the cylinder, the enter and exit points have equal values. If the ray does not intersect the cylinder, FALSE is returned, otherwise we will return TRUE.void SbCylinder::print (FILE *fp) const¶
Dump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.Author¶
