Nadradený pojem:

A
vertex may have
several attributes:

Two vertices are equivalent if and only if all their attributes are equal.

**Example:**

Consider
the following two vertices, **p** and **q**:

**p**

p.x = 0

p.y = 1

p.z = 0

p.r = 1

p.g = 0

p.b = 0

**q**

q.x = 0

q.y = 1

q.z = 0

q.r = 0

q.g = 1

q.b = 0

Are these vertices equal?

No.**p** ≠** q**.
While they have the same position, their colours are different.

- Position
- Colour
- Texture coordinate (to be discussed… stay tuned)
- Normal (to be discussed… stay tuned)

Two vertices are equivalent if and only if all their attributes are equal.

p.x = 0

p.y = 1

p.z = 0

p.r = 1

p.g = 0

p.b = 0

q.x = 0

q.y = 1

q.z = 0

q.r = 0

q.g = 1

q.b = 0

Are these vertices equal?

No.
