ID3D10Buffer interface (d3d10.h)
A buffer interface accesses a buffer resource, which is unstructured memory. Buffers typically store vertex or index data.
Inheritance
The ID3D10Buffer interface inherits from ID3D10Resource. ID3D10Buffer also has these types of members:
Methods
The ID3D10Buffer interface has these methods.
| ID3D10Buffer::GetDesc Get the properties of a buffer resource. (ID3D10Buffer.GetDesc) |
| ID3D10Buffer::Map Get a pointer to the data contained in the resource and deny GPU access to the resource. |
| ID3D10Buffer::Unmap Invalidate the pointer to the resource retrieved by ID3D10Buffer::Map and reenable GPU access to the resource. |
Remarks
Three types of buffers can be created; vertex, index, and shader-constant buffers. To create a buffer resource, call ID3D10Device::CreateBuffer.
A buffer must be bound to the pipeline before it can be accessed. Buffers can be bound to the input-assembler stage by calls to ID3D10Device::IASetVertexBuffers and ID3D10Device::IASetIndexBuffer, and to the stream-output stage by a call to ID3D10Device::SOSetTargets.
Buffers can be bound to multiple pipeline stages simultaneously for reading. A buffer can also be bound to a single pipeline stage for writing; however, the same buffer cannot be bound for reading and writing simultaneously. For more information, see binding resources.
