- Detailed Description
- 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 float r)Construct and initialize an SbCylinder instance with the given axis a and radius r.
- Member Function Documentation
- void SbCylinder::setValue (const SbLine & a, const float r)Set the axis and radius of the cylinder.
- void SbCylinder::setAxis (const SbLine & a)Set the center axis of the cylinder.
- void SbCylinder::setRadius (const float r)Set the radius of the cylinder.
- const SbLine & SbCylinder::getAxis (void) constReturn the line which is the center axis of the cylinder.
- float SbCylinder::getRadius (void) constReturn radius of cylinder.
- SbBool SbCylinder::intersect (const SbLine & l, SbVec3f & intersection) constFinds the intersection point of the ray l on the cylinder where the ray enters, and return this point in intersection.
- SbBool SbCylinder::intersect (const SbLine & l, SbVec3f & enter, SbVec3f & exit) constFind 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.
- void SbCylinder::print (FILE * fp) constDump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.

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.

SbBool SbCylinder::intersect (const SbLine & l, SbVec3f & intersection) constFinds the intersection point of the ray l on the cylinder where the ray enters, and return this point in intersection.
