1: Structured Description
Here is the rules of Structured Description.
Entities:
\( V\): \(\in \text{ the real vectors spaces }\)
\( \{p_0, ..., p_n\}\): \(\subseteq V\), \(\in \{\text{ the possibly-non-affine-independent sets of base points on } V\}\)
\(*p\): \( = \sum_{j = 0 \sim n} t^j p_j \in V\), \(t^j \in \mathbb{R}\)
//
Conditions:
\(\sum_{j = 0 \sim n} t^j = 1 \land 0 \le t^j\)
//
2: Natural Language Description
For any real vectors space, \(V\), and any possibly-non-affine-independent set of base points, \(p_0, ..., p_n \in V\), any point, \(p = \sum_{j = 0 \sim n} t^j p_j \in V\), such that \(t^j \in \mathbb{R}, \sum_{j = 0 \sim n} t^j = 1 \land 0 \le t^j\)
