Interface GeneralizedStripFlags

All Known Implementing Classes:

GeneralizedVertexList

interface GeneralizedStripFlags

A class which implements GeneralizedStripFlags provides the means to access the vertex replace code flags associated with each vertex of a generalized strip. This allows a flexible representation of generalized strips for various classes and makes it possible to provide a common subset of static methods which operate only on their topology.

Field Summary

Fields

Modifier and Type	Field and Description
static int	FRONTFACE_CCW This constant is used to indicate that triangles with counter-clockwise vertex winding are front facing.
static int	FRONTFACE_CW This constant is used to indicate that triangles with clockwise vertex winding are front facing.
static int	REPLACE_MIDDLE This flag indicates that the next triangle in the strip is defined by replacing the middle vertex of the previous triangle in the strip.
static int	REPLACE_OLDEST This flag indicates that the next triangle in the strip is defined by replacing the oldest vertex of the previous triangle in the strip.
static int	RESTART_CCW This flag indicates that a vertex starts a new strip with counter-clockwise winding.
static int	RESTART_CW This flag indicates that a vertex starts a new strip with clockwise winding.

Methods

Modifier and Type	Method and Description

Method Detail

getFlagCount

int getFlagCount()

Return the number of flags. This should be the same as the number of vertices in the generalized strip.

getFlag

int getFlag(int index)

Return the flag associated with the vertex at the specified index.
