public enum SetDataOptions

Member nameDescription
NonePortions of existing data in the buffer may be overwritten during this operation.
DiscardThe SetData operation will discard the entire buffer. A pointer to a new memory area is returned so that the direct memory access (DMA) and rendering from the previous area do not stall.
NoOverwriteThe SetData operation will not overwrite existing data in the vertex and index buffers. Specifying this option allows the driver to return immediately from a SetData operation and continue rendering.
