# SbCylinder(3iv)

class for representing a cylinder

## NAME

SbCylinder — class for representing a cylinder

## INHERITS FROM

SbCylinder

## SYNOPSIS

**#include \<Inventor/SbLinear.h\>**

Methods from class SbCylinder:

	**SbCylinder()**\
 	**SbCylinder(const SbLine &a, float r)**\
 **void**	**setValue(const SbLine &a, float r)**\
 **void**	**setAxis(const SbLine &a)**\
 **void**	**setRadius(float r)**\
 **const SbLine &**	**getAxis() const**\
 **float**	**getRadius() const**\
 **SbBool**	**intersect(const SbLine &l, SbVec3f &intersection) const**\
 **SbBool**	**intersect(const SbLine &l, SbVec3f &enter, SbVec3f &exit) const**

## DESCRIPTION

**This class defines a simple cylinder datatype. It is used by the Inventor toolkit for arguments or return values.**

## METHODS

	**SbCylinder()**\
 	**SbCylinder(const SbLine &a, float r)**\
 Constructors. One takes an axis and radius.

**void**	**setValue(const SbLine &a, float r)**\
 Change the axis and radius.

**void**	**setAxis(const SbLine &a)**\
 **void**	**setRadius(float r)**\
 Set just the axis or radius.

**const SbLine &**	**getAxis() const**\
 **float**	**getRadius() const**\
 Return the axis and radius.

**SbBool**	**intersect(const SbLine &l, SbVec3f &intersection) const**\
 **SbBool**	**intersect(const SbLine &l, SbVec3f &enter, SbVec3f &exit) const**\
 Intersect line and cylinder, returning **TRUE** if there is an intersection.
