Fig. 17 — A two-dimensional T-mesh with degree $(p_{1}, p_{2}) = (5, 3)$ . For the three (blue) nodes $z \in {(6, 4), (9, 8), (15, 13)}$ , their corresponding local knot vectors are indicated by red crosses. In the axes we indicate the indices in $I_{j}^{0}$ and, between parentheses, the value of the corresponding knots. (Color figure online)
