Method Summary

Modifier and Type	Method	Description
(package private) void	build(List<NvEdgeInfo> edgeInfos, List<NvFaceInfo> faceInfos)	Builds a strip forward as far as we can go, then builds backwards, and joins the two lists

 int experimentId)

Method Details

isExperiment

final boolean isExperiment()

Returns:

true if the experiment id is >= 0

IsInStrip

final boolean IsInStrip(NvFaceInfo faceInfo)

Parameters:

faceInfo - the face info

Returns:

true if it's in the strip

sharesEdge

boolean sharesEdge(NvFaceInfo faceInfo,
 List<NvEdgeInfo> edgeInfos)

Parameters:

faceInfo - the face info

edgeInfos - the edge infos

Returns:

true if the input face and the current strip share an edge

combine

void combine(List<NvFaceInfo> forward,
 List<NvFaceInfo> backward)

take the given forward and backward strips and combine them together

Parameters:

forward - the forward strips

backward - the backward strips

unique

boolean unique(List<NvFaceInfo> faceVec,
 NvFaceInfo face)

Parameters:

faceVec - the face list

face - the face

Returns:

true if the face is "unique", i.e. has a vertex which doesn't exist in the faceVec

isMarked

boolean isMarked(NvFaceInfo faceInfo)

If either the faceInfo has a real strip index because it is already assign to a committed strip OR it is assigned in an experiment and the experiment index is the one we are building for, then it is marked and unavailable

Parameters:

faceInfo - the face info

Returns:

true if the face is marked

markTriangle

void markTriangle(NvFaceInfo faceInfo)

Marks the face with the current strip ID

Parameters:

faceInfo - the face info

build

void build(List<NvEdgeInfo> edgeInfos,
 List<NvFaceInfo> faceInfos)

Builds a strip forward as far as we can go, then builds backwards, and joins the two lists

Parameters:

edgeInfos - the edge infos

faceInfos - the face infos
