Class PolygonMesh

java.lang.Object
  de.grogra.imp3d.objects.PolygonsBase
      de.grogra.imp3d.objects.PolygonMesh

All Implemented Interfaces:

ContextDependent, Polygons, Polygonization, java.io.Serializable

public class PolygonMesh
extends PolygonsBase

This class encapsulates a static PolygonArray. Polygonalization is just making a copy of the stored polygon array to the output array.

Method Detail

computeMaxMin

public float[] computeMaxMin()

Computes max and min values of vertex data. Needed for BoundingBox computation.

Returns:

Array{MaxX, MinX, MaxY, MinY, MaxZ, MinZ}

computeMaxMin

public float[] computeMaxMin(Matrix4d m)

Computes max and min values of vertex data. Needed for BoundingBox computation.

Parameters:

m - Use can use m to transform all vertices to global coordinates.

Returns:

Array{MaxX, MinX, MaxY, MinY, MaxZ, MinZ}

getIndexData

public final int[] getIndexData()

getNormalData

public final float[] getNormalData()

getStamp

public int getStamp()

Overrides:

getStamp in class PolygonsBase

getTextureData

public final float[] getTextureData()

getVertexData

public final float[] getVertexData()

incrementStamp

public void incrementStamp()

multiplyMatrixWithTuple3d

public static void multiplyMatrixWithTuple3d(Matrix4d matrix,
                                             Tuple3d point)

Multiplies matrix with point and writes result into point.

Parameters:

matrix -

point -

polygonize

public void polygonize(ContextDependent source,
                       GraphState gs,
                       PolygonArray out,
                       int flags,
                       float flatness)

Description copied from interface: Polygonization

Performs the polygonization of the source into polygons. The field out.userObject is not modified.

Parameters:

source - the data source as reported by a previous invocation of Polygonizable.getPolygonizableSource(GraphState) with the same gs

gs - the current graph state

out - the polygons are written to out

flags - combination of bit masks

flatness - a parameter for the degree of flatness, a typical value is 1

setIndexData

public void setIndexData(IntList indexData)

setNormalData

public void setNormalData(float[] normalData)

setTextureData

public void setTextureData(float[] textureData)

setVertexData

public void setVertexData(FloatList vertexData)

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 PolygonsBase

Parameters:

cache - a cache entry to write the stamp

gs - the current graph state
