etc.) from a specific rank (when running in parallel). Use **ArrayName** | |||

property to select the array association and array name. Use | |||

**ElementId* property to set the element number to extract the value to | |||

label with. When running on multiple ranks, use **ProcessId** property | |||

to select the rank of interest. The **Prefix** property can be used to | |||

specify a string that will be used as the prefix to the generated | |||

annotation text. | |||

== | ==Annotate Global Data== | ||

Filter for annotating with global data (designed for ExodusII reader) | |||

Annotate Global Data provides a simpler API for creating text | |||

annotations using vtkPythonAnnotationFilter. Instead of users | |||

specifying the annotation expression, this filter determines the | |||

expression based on the array selected by limiting the scope of the | |||

functionality. This filter only allows the user to annotate using | |||

"global-data" aka field data and specify the string prefix to use. If | |||

the field array chosen has as many elements as number of timesteps, | |||

the array is assumed to be "temporal" and indexed using the current | |||

timestep. | |||

the point and cell attributes of the inputs. Any inputs | |||

without the same number of points and cells as the first | |||

input are ignored. The input data sets must already be | |||

collected together, either as a result of a reader that | |||

loads multiple parts (e.g., EnSight reader) or because the | |||

Group Parts filter has been run to form a collection of | |||

data sets. | |||

==CacheKeeper== | |||

vtkPVCacheKeeper manages data cache for flip book | |||

animations. When caching is disabled, this simply acts as a pass through | |||

filter. When caching is enabled, is the current time step has been | |||

previously cached then this filter shuts the update request, otherwise | |||

propagates the update and then cache the result for later use. The | |||

current time step is set using SetCacheTime(). | |||

==Calculator== | |||

Compute new attribute arrays as function of existing arrays. | |||

The Calculator filter computes a new data array or new point | |||

coordinates as a function of existing scalar or vector arrays. If | |||

point-centered arrays are used in the computation of a new data array, | |||

the resulting array will also be point-centered. Similarly, | |||

computations using cell-centered arrays will produce a new | |||

cell-centered array. If the function is computing point coordinates, | |||

the result of the function must be a three-component vector. | |||

The Calculator interface operates similarly to a scientific | |||

calculator. In creating the function to evaluate, the standard order | |||

of operations applies. Each of the calculator functions is described | |||

below. Unless otherwise noted, enclose the operand in parentheses | |||

using the ( and ) buttons. | |||

- Clear: Erase the current function (displayed in the read-only text | |||

box above the calculator buttons). | |||

- /: Divide one scalar by another. The operands for this function are | |||

not required to be enclosed in parentheses. | |||

- *: Multiply two scalars, or multiply a vector by a scalar (scalar multiple). | |||

The operands for this function are not required to be enclosed in parentheses. | |||

- -: Negate a scalar or vector (unary minus), or subtract one scalar or vector | |||

from another. The operands for this function are not required to be enclosed | |||

in parentheses. | |||

- +: Add two scalars or two vectors. The operands for this function are not | |||

required to be enclosed in parentheses. | |||

- sin: Compute the sine of a scalar. cos: Compute the cosine of a scalar. | |||

- tan: Compute the tangent of a scalar. | |||

- asin: Compute the arcsine of a scalar. | |||

- acos: Compute the arccosine of a scalar. | |||

- atan: Compute the arctangent of a scalar. | |||

- sinh: Compute the hyperbolic sine of a scalar. | |||

- cosh: Compute the hyperbolic cosine of a scalar. | |||

- tanh: Compute the hyperbolic tangent of a scalar. | |||

- min: Compute minimum of two scalars. | |||

- max: Compute maximum of two scalars. | |||

- x^y: Raise one scalar to the power of another scalar. The operands for | |||

this function are not required to be enclosed in parentheses. | |||

- sqrt: Compute the square root of a scalar. | |||

- e^x: Raise e to the power of a scalar. | |||

- log: Compute the logarithm of a scalar (deprecated. same as log10). | |||

- log10: Compute the logarithm of a scalar to the base 10. | |||

- ln: Compute the logarithm of a scalar to the base 'e'. | |||

- ceil: Compute the ceiling of a scalar. floor: Compute the floor of a scalar. | |||

- abs: Compute the absolute value of a scalar. | |||

- v1.v2: Compute the dot product of two vectors. The operands for this | |||

function are not required to be enclosed in parentheses. | |||

- cross: Compute cross product of two vectors. | |||

- mag: Compute the magnitude of a vector. | |||

- norm: Normalize a vector. | |||

The operands are described below. The digits 0 - 9 and the decimal | |||

point are used to enter constant scalar values. **iHat**, **jHat**, | |||

and **kHat** are vector constants representing unit vectors in the X, | |||

Y, and Z directions, respectively. The scalars menu lists the names of | |||

the scalar arrays and the components of the vector arrays of either | |||

the point-centered or cell-centered data. The vectors menu lists the | |||

names of the point-centered or cell-centered vector arrays. The | |||

function will be computed for each point (or cell) using the scalar or | |||

vector value of the array at that point (or cell). The filter operates | |||

on any type of data set, but the input data set must have at least one | |||

scalar or vector array. The arrays can be either point-centered or | |||

cell-centered. The Calculator filter's output is of the same data set | |||

type as the input. | |||

== | ==Cell Centers== | ||

Create a point (no geometry) at the center of each input cell.The Cell Centers | |||

filter places a point at the center of each cell in the | |||

input data set. The center computed is the parametric | |||

center of the cell, not necessarily the geometric or | |||

bounding box center. The cell attributes of the input will | |||

be associated with these newly created points of the | |||

output. You have the option of creating a vertex cell per | |||

point in the outpuut. This is useful because vertex cells | |||

are rendered, but points are not. The points themselves | |||

could be used for placing glyphs (using the Glyph filter). | |||

components, is discussed in section 7.4. If an implicit | |||

function is selected, the clip filter returns that portion | |||

of the input data set that lies inside the function. If | |||

Scalars is selected, then the user must specify a scalar | |||

array to clip according to. The clip filter will return | |||

the portions of the data set whose value in the selected | |||

Scalars array is larger than the Clip value. Regardless of | |||

the selection from the Clip Function menu, if the Inside | |||

Out option is checked, the opposite portions of the data | |||

set will be returned. This filter operates on all types of | |||

data sets, and it returns unstructured grid data on | |||

Add button, or press Enter. To instead add several evenly | |||

spaced contours, use the controls in the Generate range of | |||

values section. Select the number of contour values to | |||

generate using the Number of Values slider. The Range | |||

slider controls the interval in which to generate the | |||

contour values. Once the number of values and range have | |||

been selected, click the Generate button. The new values | |||

will be added to the Contour Values list. To delete a | |||

value from the Contour Values list, select the value and | |||

click the Delete button. (If no value is selected, the | |||

last value in the list will be removed.) Clicking the | |||

Delete All button removes all the values in the list. If | |||

no values are in the Contour Values list when Accept is | |||

pressed, the current value of the New Value slider will be | |||

used. In addition to selecting contour values, you can | |||

also select additional computations to perform. If any of | |||

Compute Normals, Compute Gradients, or Compute Scalars is | |||

== | ==Delaunay 2D== | ||

Create 2D Delaunay triangulation of input points. It expects a vtkPointSet as input and produces vtkPolyData as output. The points are expected to be in a mostly planar distribution. | |||

Delaunay2D is a filter that constructs a 2D Delaunay | |||

triangulation from a list of input points. These points | |||

may be represented by any dataset of type vtkPointSet and | |||

subclasses. The output of the filter is a polygonal | |||

dataset containing a triangle mesh. The 2D Delaunay | |||

triangulation is defined as the triangulation that | |||

satisfies the Delaunay criterion for n-dimensional | |||

simplexes (in this case n=2 and the simplexes are | |||

triangles). This criterion states that a circumsphere of | |||

each simplex in a triangulation contains only the n+1 | |||

defining points of the simplex. In two dimensions, this | |||

translates into an optimal triangulation. That is, the | |||

maximum interior angle of any triangle is less than or | |||

equal to that of any possible triangulation. Delaunay | |||

triangulations are used to build topological structures | |||

from unorganized (or unstructured) points. The input to | |||

this filter is a list of points specified in 3D, even | |||

though the triangulation is 2D. Thus the triangulation is | |||

constructed in the x-y plane, and the z coordinate is | |||

ignored (although carried through to the output). You can | |||

use the option ProjectionPlaneMode in order to compute the | |||

best-fitting plane to the set of points, project the | |||

points and that plane and then perform the triangulation | |||

using their projected positions and then use it as the | |||

plane in which the triangulation is performed. The | |||

Delaunay triangulation can be numerically sensitive in | |||

some cases. To prevent problems, try to avoid injecting | |||

points that will result in triangles with bad aspect | |||

ratios (1000:1 or greater). In practice this means | |||

inserting points that are "widely dispersed", and enables | |||

smooth transition of triangle sizes throughout the mesh. | |||

(You may even want to add extra points to create a better | |||

point distribution.) If numerical problems are present, | |||

you will see a warning message to this effect at the end | |||

of the triangulation process. Warning: Points arranged on | |||

a regular lattice (termed degenerate cases) can be | |||

triangulated in more than one way (at least according to | |||

the Delaunay criterion). The choice of triangulation (as | |||

implemented by this algorithm) depends on the order of the | |||

input points. The first three points will form a triangle; | |||

other degenerate points will not break this triangle. | |||

Points that are coincident (or nearly so) may be discarded | |||

by the algorithm. This is because the Delaunay | |||

triangulation requires unique input points. The output of | |||

the Delaunay triangulation is supposedly a convex hull. In | |||

certain cases this implementation may not generate the | |||

convex hull. | |||

== | ==Delaunay 3D== | ||

Create a 3D Delaunay triangulation of input points. It expects a vtkPointSet as input and produces vtkUnstructuredGrid as output.Delaunay3D is a filter that constructs | |||

a 3D Delaunay triangulation from a list of input points. These points may be | |||

represented by any dataset of type vtkPointSet and subclasses. The output of | |||

the filter is an unstructured grid dataset. Usually the output is a tetrahedral | |||

mesh, but if a non-zero alpha distance value is specified (called the "alpha" | |||

value), then only tetrahedra, triangles, edges, and vertices lying within the | |||

alpha radius are output. In other words, non-zero alpha values may result in | |||

arbitrary combinations of tetrahedra, triangles, lines, and vertices. (The | |||

notion of alpha value is derived from Edelsbrunner's work on "alpha shapes".) | |||

The 3D Delaunay triangulation is defined as the triangulation that satisfies | |||

the Delaunay criterion for n-dimensional simplexes (in this case n=3 and the | |||

simplexes are tetrahedra). This criterion states that a circumsphere of each | |||

simplex in a triangulation contains only the n+1 defining points of the | |||

simplex. (See text for more information.) While in two dimensions this | |||

translates into an "optimal" triangulation, this is not true in 3D, since a | |||

measurement for optimality in 3D is not agreed on. Delaunay triangulations are | |||

used to build topological structures from unorganized (or unstructured) points. | |||

The input to this filter is a list of points specified in 3D. (If you wish to | |||

create 2D triangulations see Delaunay2D.) The output is an unstructured grid. | |||

The Delaunay triangulation can be numerically sensitive. To prevent problems, | |||

try to avoid injecting points that will result in triangles with bad aspect | |||

ratios (1000:1 or greater). In practice this means inserting points that are | |||

"widely dispersed", and enables smooth transition of triangle sizes throughout | |||

the mesh. (You may even want to add extra points to create a better point | |||

distribution.) If numerical problems are present, you will see a warning | |||

message to this effect at the end of the triangulation process. Warning: Points | |||

arranged on a regular lattice (termed degenerate cases) can be triangulated in | |||

more than one way (at least according to the Delaunay criterion). The choice of | |||

triangulation (as implemented by this algorithm) depends on the order of the | |||

input points. The first four points will form a tetrahedron; other degenerate | |||

points (relative to this initial tetrahedron) will not break it. Points that | |||

are coincident (or nearly so) may be discarded by the algorithm. This is | |||

because the Delaunay triangulation requires unique input points. You can | |||

control the definition of coincidence with the "Tolerance" instance variable. | |||

The output of the Delaunay triangulation is supposedly a convex hull. In | |||

certain cases this implementation may not generate the convex hull. This | |||

behavior can be controlled by the Offset instance variable. Offset is a | |||

multiplier used to control the size of the initial triangulation. The larger | |||

the offset value, the more likely you will generate a convex hull; and the more | |||

likely you are to see numerical problems. The implementation of this algorithm | |||

varies from the 2D Delaunay algorithm (i.e., Delaunay2D) in an important way. | |||

When points are injected into the triangulation, the search for the enclosing | |||

tetrahedron is quite different. In the 3D case, the closest previously inserted | |||

point point is found, and then the connected tetrahedra are searched to find | |||

the containing one. (In 2D, a "walk" towards the enclosing triangle is | |||

performed.) If the triangulation is Delaunay, then an enclosing tetrahedron | |||

will be found. However, in degenerate cases an enclosing tetrahedron may not be | |||

found and the point will be rejected. | |||
