vertexZ

Used to obtain vertex coordinates.

float vertexZ(int32_t vertexIndex) const;

vertexIndex

The (zero-based) index of the vertex being queried. Must be greater than or equal to zero, and less than the value returned by vertices().

The Z (vertical) coordinate for the specified vertex.

Use vertexIndex() to obtain unique vertex indices for vertices in a face.

float vertexZ(int vertexIndex);

float vertexZ(int vertexIndex);
