# class FieldData

FieldData represents multiple fields of data. Each field is implemented as an ValueArray object, that has a unique name, and can have complex components (such as scalars, vectors, quaternions, tensors or matrices). All fields are assumed to be of the same length. IFieldData can be seen as an array with complex tuples, where the component can be of different types.

# CopyCombine3Tuples

CopyCombine3Tuples combines the data from three tuples into a destination tuple. The call works like CobineTuples, but there is three source tuples, and two alpha values. the destination will be weighted by the values: alpha_3 = 1-(alpha_1 + alpha_2) dest = src_1*alpha_1 + src_2*alpha_2 + src_3*alpha_3 This field data object can be used as the source field data object to copy within the object.

# IndexedCombine

Works like IndexedCopy, but uses two consecutive ids in the idtable, and a blend value from the blendtable. The idtable contains (idtable_cnt*2) indices and blendtable contains idtable_cnt blend values. Does the blend: dest = src1*(1-blend) + src2*blend The FieldData must have enough tuples to hold the new data.

# IndexedCopy

Copies tuples from a source field data object through an id table. The id table dictates the order in which the tuples are to be copied. E.g. If the first item in the id table has the value 14, then the tuple with id 14 in the source array will be copied to the first tuple in this array. Note! All ids in the id table must be valid ids of tuples in the source field data object. The id table is assumed to have a tuple size of 1. The source and this field data object must have the same underlaying data fields, of the same type and the same tuple sizes. The FieldData must have enough tuples to hold the new data.

void IndexedCopy( spFieldData source , spRidArray idtable , rid startId );

void IndexedCopy(spFieldData source, spRidArray idtable, rid startId);

spFieldData NewCopy(copy_data: bool)

# NewPackedCopy

Like NewCopy, NewPackedCopy creates a field data object with the same underlying data and tuple settings as the source field data object. However, NewPackedCopy only copies unique tuples, and if the index_array parameter is set, this index array will contain the same number of tuples as the source field data object, and with the ids of a specific tuples within the new copy of the field data object.

void RemoveField(string name);

None RemoveField(name: str)
