5.93. Weights (element)

5.93.1. Attributes

5.93.2. Description

This element defines a weight vector. The weights are used to calculate the key positions in an interpolator space from the positions of the interpolator generators. The key positions build the vertices of the interpolator polygon (Section 2.3).

The integer value of the dim attribute defines the dimension of the weight vector. Since the weight vector is used to make an affine combination of geometric elements (the interpolation generators), its coordinates must be positive and their sum must be unity. The integer value of the index attribute defines the rank of the weight vector in the tabweights weight matrix.

5.93.3. Expected child

None.

5.93.4. Example

The example below defines the weight vector (0.0, 0.6, 0.4). It is expected to be the first row of a 3-column weight matrix that define key positions from three interpolation generators.

<weights index="1" dim="3">
  0.0    0.6      0.4
</weight>
