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 float r)

Construct and initialize an SbCylinder instance with the given axis a and radius r.

void SbCylinder::setValue (const SbLine & a, const float r)

Set the axis and radius of the cylinder.

See also

void SbCylinder::setAxis (const SbLine & a)

Set the center axis of the cylinder.

See also

void SbCylinder::setRadius (const float r)

Set the radius of the cylinder.

See also

const SbLine & SbCylinder::getAxis (void ) const

Return the line which is the center axis of the cylinder.

See also

float SbCylinder::getRadius (void ) const

Return radius of cylinder.

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 fp file stream. Only works in debug version of library, method does nothing in an optimized build.
