Vector result values for a part.
A vector result is a three dimensional value specifying direction and magnitude. DataPartVector contains an array of Vec3d's which can be set with single precision (float) or double precision (double). Internal storage is in double precision.
DataPartVector object contains the vector result values corresponding to a DataPart. This means that the number of result values in each vector part must match the number of nodes/elements in the corresponding part (depending on mapping type). For instance, a node mapped result will need the same number of result values in the vector part as there are nodes in the part.
A DataPartVector is a child of a DataResultVector in the same way as a DataPart is a child of a DataGeometry. The DataResultVector must have the same number of child parts as the DataGeometry.
Values are inserted using setValue(), setValues() or setValuesFloat(). Get the number of values with count() and query a specific value using value() with an index.
Example of how to add a node based vector result to a geometry consisting of only one triangle.
Create the DataResultVector object with a unique id and node based result mapping.
The result array must have one value for each node in the triangle. Resize the array before inserting the results.
Add the vector part to the result vector.
The number of result values in each vector part must match the number of nodes/elements in the part (depending on mapping type). Here the result is a single triangle with node based mapping, so the scalar part must contain three vector result values.
Add the result vector to the state (DataState) for the corresponding geometry (DataGeometry) geo.

cee::ug::DataPartVector::DataPartVector | ( | ) |
Constructs an empty object.
size_t cee::ug::DataPartVector::count | ( | ) | const |
Returns the number of result values.
bool cee::ug::DataPartVector::magnitudeRange | ( | double * | min, |
double * | max | ||
) | const |
Gets minimum and maximum vector magnitude.
const double * cee::ug::DataPartVector::rawValuePointer | ( | ) | const |
Returns a raw pointer to the value array.
double * cee::ug::DataPartVector::rawValuePointer | ( | ) |
Returns a modifiable raw pointer to the value array.
void cee::ug::DataPartVector::resize | ( | size_t | valueCount | ) |
Sets the number of values in the object.
The current values in the object will be kept up to the given count (if shrinking).
void cee::ug::DataPartVector::setValue | ( | size_t | index, |
const Vec3d & | value | ||
) |
Sets the value at the given index.
void cee::ug::DataPartVector::setValues | ( | const std::vector< Vec3d > & | values | ) |
Sets the vector values from a std::vector of Vec3ds.
void cee::ug::DataPartVector::setValues | ( | const double | values[], |
size_t | vectorCount | ||
) |
Sets the vector values from an array of doubles.
The array must be at least vectorCount*3 items long, as vectorCount is the number of result values, not the number of floats in the array.
void cee::ug::DataPartVector::setValuesFloat | ( | const float | values[], |
size_t | vectorCount | ||
) |
Sets the vector values from an array of floats.
The array must be at least vectorCount*3 items long, as vectorCount is the number of result values, not the number of floats in the array.
Note that this is only provided for convenience, and that the nodes will internally be stored as doubles
void cee::ug::DataPartVector::setValueUndefined | ( | size_t | index | ) |
Sets an undefined value at the given index.
Vec3d cee::ug::DataPartVector::value | ( | size_t | index | ) | const |
Returns the result value for the given index.
