VertexBuffer is an abstraction of low level openGL Vertex Buffer Object.
It is used to save an array of vertices.
|
static |
Create an instance of VertexBuffer.
Size in bytes of one vertex. The number of vertex. A hint to indicate whether the vertexBuffer are updated frequently or not to let GL optimise it.
