Method Detail

dependsOnContext

public boolean dependsOnContext()

Description copied from interface: ContextDependent

Determines whether this object actually depends on context.

Specified by:

dependsOnContext in interface ContextDependent

Returns:

true iff this object depends on context

getDimension

public int getDimension(GraphState gs)

Specified by:

getDimension in interface VertexSet

getKnot

public float getKnot(int dim,
                     int index,
                     GraphState gs)

Specified by:

getKnot in interface KnotVector

getProfile

public BSplineCurve getProfile()

getTrajectory

public BSplineCurve getTrajectory()

getUDegree

public int getUDegree(GraphState gs)

Specified by:

getUDegree in interface BSplineSurface

getUSize

public int getUSize(GraphState gs)

Specified by:

getUSize in interface VertexGrid

getVDegree

public int getVDegree(GraphState gs)

Specified by:

getVDegree in interface BSplineSurface

getVertexIndex

public int getVertexIndex(int u,
                          int v,
                          GraphState gs)

Specified by:

setProfile

public void setProfile(BSplineCurve value)

setTrajectory

public void setTrajectory(BSplineCurve value)

writeStamp

public void writeStamp(Cache.Entry cache,
                       GraphState gs)

Description copied from interface: ContextDependent

Writes a stamp of the context into cache. Based on this stamp, a cache detects whether the context of this object has changed or not.

Specified by:

writeStamp in interface ContextDependent

Overrides:

writeStamp in class ContextDependentBase

Parameters:

cache - a cache entry to write the stamp

gs - the current graph state
