Detailed Description

Represents a vertex in the mesh.

Each vertex has a 3-component coordinate and a scalar value associated with it. The factor provides a mechanism to specify precision of the coordinate comparison. Although coordinates are provided as floating-point numbers, they are stored as integers. The integer value is computed as floor (x * factor) Therefore a factor of 100 would ensure a precision of 0.01 in the comparison.
