Container/manager of fields and domains within a region.
Container/manager of fields and domains within a region.
Note that fieldmodule create field methods documented as supporting 'automatic scalar broadcast' for their source field arguments work as follows: if given a mix of scalar and vector source fields, the scalar value is applied to each component of the vector, e.g. the result of ADD(CONSTANT([1 2 3 4], CONSTANT([10]) is [11 12 13 14]. Internally it works by substituing the scalar operand with a concatenate field with the same number of components as the vector operand, but filled with the scalar value.

Calculation will only succeed in any element with xi-dimension equal to the number of components in the <coordinate_field>. Sets the number of components in return field to the product of the number of components in the <source_field> and <coordinate_field>. Note the <source_field> does not have to be a scalar.

Creates a field applying the ITK discrete gaussian image filter to the source field. This means that each pixel value in the new field is based on a weighted average of the pixel and the surrounding pixel values from the source field. Pixels further away are given a lower weighting. Increasing the variance increases the width of the gaussian distribution used and hence the number of pixels used to calculate the weighted average. This smooths the image more. A limit is set on the max_kernel_width used to approximate the guassian to ensure the calculation completes.

Creates a projection field returning the result of a matrix multiplication with perspective division on the source field vector. The source_field vector is expanded to a homogeneous coordinate by appending a component of value 1, which is multiplied by the projection_matrix_field, and the extra calculated value resulting from the unit component is used to divide through each of the other components to give a perspective projection in the resulting field.

Creates a field which performs a coordinate transformation of vectors from their original coordinate system and coordinate positions, to the coordinate system of this field. Sets the number of components in returned field to 3 times the number of vectors expected from the source vector_field.
| vectorField | Vector field to be transformed. Can be a single vector (1,2 or 3 components), two vectors (4 or 6 components) or three vectors (9 components). |
| coordinateField | Field giving location where vector value is from. |
|
inline |
Creates a field whose component values are 1 if that component of source_field_one OR source_field_two is non-zero (but not both), 0 otherwise. Automatic scalar broadcast will apply, see field.h.
| sourceField1 | First input field |
| sourceField2 | Second input field |
|
inline |
Create an optimisation object for optimising values and parameters of fields from a field module.
|
inline |
Defines, for all elements of all meshes in field module, face elements of dimension one lower in the associated face mesh, and all their faces recursively down to 1 dimensional lines.
faces for.
|
inline |
Decrement cache level or end caching of changes for this field module. Call matching fieldmodule begin change method before making multiple changes and call this afterwards. When change level is restored to zero, cached change messages are sent out to clients.
|
inline |
Returns the field of the specified name from the field module.
| fieldName | The name of the field to find. |
|
inline |
Get a handle to the default mesh of a given dimension. Cmgui is currently limited to 1 mesh of each dimension from 1 to 3. These meshes have default names of "mesh_Nd", where "N" is the dimension.
| dimension | The dimension of the mesh from 1 to 3. |
|
inline |
Get a handle to a finite element mesh from its name. A mesh is the container of elements of a fixed dimension. Valid names may be any element_group field, or any of the following special names: "mesh3d" = 3-D elements. "mesh2d" = 2-D elements including faces of 3-D elements. "mesh1d" = 1-D elements including faces (lines) of 2-D elements. Note that the default names for element group fields created from a group is GROUP_NAME.MESH_NAME, with mesh names as above.
| meshName | The name of the finite element mesh. |
|
inline |
Get a handle to a nodeset by its field domain type, either CMZN_FIELD_DOMAIN_TYPE_NODES or CMZN_FIELD_DOMAIN_TYPE_DATAPOINTS.
| domainType | CMZN_FIELD_DOMAIN_TYPE_NODES or CMZN_FIELD_DOMAIN_TYPE_DATAPOINTS. |
|
inline |
Get a handle to a nodeset from its name in the field module. A nodeset is the container of nodes - i.e. cmzn_node objects. Valid names may be any node_group field, or the following special names: "nodes" = the primary set of nodes for a region, able to be indexed by elements for storing or mapping to finite element field parameters. "datapoints" = an additional set of nodes generally used to represent data points, not for finite element field parameters. Note that the default names for node group fields created from a group is GROUP_NAME.NODESET_NAME, with nodeset names as above.
| nodeset_name | The name of the nodeset. |
|
inline |
Return the C handle of the Fieldmodule object.
|
inline |
Finds or creates a time sequence in the field module which matches the sequence of times provided.
| timesInCount | The size of the times array. |
| timesIn | Array of times. Note later times must not be less than earlier times. |
|
inline |
Gets the region this field module can create fields for.
|
inline |
Check if this is a valid Fieldmodule object.
|
inline |
Write the json file describing the fields in this fieldmodule. This may change the current fields' definition.
The string containing json description
|
inline |
Write the json file describing the fields in this fieldmodule, which can be used to store the current cmzn_field settings.
