SubPatch

public SubPatch(Vector3d a,
                Vector3d b,
                Vector3d c)

Constructor, creates a new SubPatch.

Parameters:

a - vertice 1

b - vertice 2

c - vertice 3

Method Detail

clearFFMap

public void clearFFMap()

Clears the form factor map.

createMesh

public MyMeshVolume createMesh()

Converts this patch into a mesh.

Returns:

Converts this patch into a mesh.

ffMapContains

public boolean ffMapContains(java.util.List<SubPatch> deprecatedPatches)

Checks whether, the list of deprecated patches contains this patch.

Parameters:

deprecatedPatches - the list of deprecated patches.

Returns:

getCenter

public Vector3d getCenter()

Return the center of this patch.

Returns:

Return the center of this patch.

getFFMap

public java.util.Map<SubPatch,FormFactor> getFFMap()

Returns the form factor map.

Returns:

Returns the form factor map.

getMaxEdgeCount

public int getMaxEdgeCount()

Description copied from interface: Mesh

Returns the maximum number of edges of a single polygon of the mesh.

Specified by:

getMaxEdgeCount in interface Mesh

Returns:

maximum number of edges

getMaxRadDifference

public float getMaxRadDifference(SubPatch other)

Returns the maximum difference of radiosity color.

Parameters:

other - another patch.

Returns:

Returns the maximum difference of radiosity color.

getNormal

public Vector3d getNormal()

Returns the normal vector of this patch.

Returns:

Returns the normal vector of this patch.

getNormal

public void getNormal(int index,
                      Tuple3d out)

Description copied from interface: Mesh

Gets the normal vector of normal index. The normal vector is not necessarily normalized.

Specified by:

getNormal in interface Mesh

Parameters:

index - normal number

out - normal vector will be placed in here

getNormalCount

public int getNormalCount()

Description copied from interface: Mesh

Returns the number of normals of the mesh.

Specified by:

getNormalCount in interface Mesh

Returns:

number of normals

getPolygon

public int getPolygon(int index,
                      int[] indicesOut,
                      int[] normalsOut)

Description copied from interface: Mesh

Writes the vertex indices of polygon index to indicesOut and the normal indices to normalsOut and returns the number of vertices of the polygon. If the mesh is closed (see Mesh.isClosed()), inside and outside are determined by the ordering of the vertices: when seen from the outside, vertices have to be oriented in a counter-clockwise manner. Then also the normal vectors have to point to the outside.

Specified by:

getPolygon in interface Mesh

Parameters:

index - polygon number

indicesOut - the vertex indices will be placed in here

normalsOut - the normal indices will be placed in here

Returns:

number of vertex indices of polygon
