Detailed Description

Shape generator that generates a sphere.

Constructor & Destructor Documentation

GLUsphereProducer::GLUsphereProducer	(	GLdouble	radius,
		GLint	slices,
		GLint	stacks
	)

Construct a new sphere shape generator

Parameters:

	radius	Specifies the radius of the sphere.
	slices	Specifies the number of subdivisions around the z-axis. These subdivisions are analogous to the slices of an orange. These also match longitude lines on the globe.
	stacks	Specifies the number of subdivisions along the z-axis. These match the latitude lines on the globe.

Member Function Documentation

unsigned GLUsphereProducer::element_count

(

void

)

const [virtual]

Get the number of elements used to draw primitives for the shape

This can be used in the constructor for derived classes, for example, to determine how much storage to allocate for element data.

Implements GLUshapeProducer.

void GLUsphereProducer::generate

(

GLUshapeConsumer *

consumer

)

const [virtual]

Generate the primitive

Causes the data for the primitive to be generated. This will result in the vertex, begin_primitive, index, and end_primitive methods of consumer being invoked with the data as it is generated.

Implements GLUshapeProducer.

unsigned GLUsphereProducer::primitive_count

(

void

)

const [virtual]

Get the number of primitves used to draw the shape

This can be used in the constructor for derived classes, for example, to determine the primitive count for a call to glMultiDrawElements or to determine how much padding to allocate for restart values used with primitive restart.

Implements GLUshapeProducer.

unsigned GLUsphereProducer::vertex_count

(

void

)

const [virtual]

Get the number of vertices in the shape

This can be used in the constructor for derived classes, for example, to determine how much storage to allocate for vertex data.

Implements GLUshapeProducer.
