Cylinder
defines a cylindrical geometry. The cylinder is
defined by a base radius, top radius, height, slices and stacks. The two
radii define the size of the ends of the cylinder. The top radius can be
zero, creating a cone. The height defines the length of the cylinder, while
the slices and stacks determine the number of vertices that make up the
cylinder. The higher the slices and stacks, the better the quality of the
image, but framerate will suffer.

Cylinder
public Cylinder(double baseRadius,
double topRadius,
double height,
int slices,
int stacks)
- Constructor defines the attributes of the cylinder and prepares it
to be rendered via a call to
initialize
- Parameters:
baseRadius
- size of the base.topRadius
- size of the topheight
- length of the cylinder.slices
- The number of subdivisions around the z-axis.stacks
- The number of subdivisions along the z-axis.
- Throws:
MonkeyRuntimeException
- if any parameter other than top radius
is zero or less.
render
public void render()
render
handles rendering the cylinder to the view context.
- Specified by:
render
in interface Geometry
- Specified by:
render
in class Quadric
setBaseRadius
public void setBaseRadius(double baseRadius)
setBaseRadius
sets the base size of the cylinder.
- Parameters:
baseRadius
- the new base size of the cylinder.
- Throws:
MonkeyRuntimeException
- if the baseRadius is less than or equal
to zero.
setTopRadius
public void setTopRadius(double topRadius)
setTopRadius
sets the top size of the cylinder. If it is
set to zero, the cylinder is essentially a cone.
- Parameters:
topRadius
- the size of the top of the cylinder.
- Throws:
MonkeyRuntimeException
- if the top radius is less than zero.
setHeight
public void setHeight(double height)
setHeight
sets the length of the cylinder.
- Parameters:
height
- the new height of the cylinder.
- Throws:
MonkeyRuntimeException
- if the top radius is less than or
equal to zero.
setSlices
public void setSlices(int slices)
setSlices
sets the number of slices for this cylinder.
- Parameters:
slices
- the number of slices for the cylinder.
- Throws:
MonkeyRuntimeException
- if slices is less than or equal to zero.
setStacks
public void setStacks(int stacks)
setStacks
sets the number of stacks for this cylinder.
- Parameters:
stacks
- the number of stacks for the cylinder.
- Throws:
MonkeyRuntimeException
- if stacks is less than or equal to zero.
getPoints
public Vector[] getPoints()
- Description copied from interface:
Geometry
getPoints
returns an array of Vectors that represents
each point that makes up the piece of geometry.
- Returns:
- the array of vectors for the points.
