VertexCount : integer

read-only

Returns the number of vertices that have a complete set of data stored.

var VertexCount : Integer

---

Methods

---

AddAttribute : Void

Adds an attribute to the definition of the vertices that are to be stored. Add the attributes in the order that they should be stored in memory on a vertex. |Name|Type|Description| |---|---|---| |semantic|VertexSemantic| | |elementType|VertexElementType| | |elementCount|integer| |

function AddAttribute(semantic : VertexSemantic, elementType : VertexElementType, elementCount : Integer)

---

AddByte : Void

Adds data as bytes to the buffer, data is expected in the order of the attributes, one vertex after another. |Name|Type|Description| |---|---|---| |value|integer| |

function AddByte(value : Integer)

---

function ClearData()

---

GetAttributes : vertexsemanticrange

Returns a range of attribute semantics in the order that they were added. |Name|Type|Description| |---|---|---|

function GetAttributes() : VertexSemanticRange

---

GetElementCount : integer
