ID3D11DeviceContext::Draw method
Draw non-indexed, non-instanced primitives.
Syntax
void Draw( [in] UINT VertexCount, [in] UINT StartVertexLocation );
Parameters
- VertexCount [in]
-
Type: UINT
Number of vertices to draw.
- StartVertexLocation [in]
-
Type: UINT
Index of the first vertex, which is usually an offset in a vertex buffer.
Return value
Returns nothing.
Remarks
Draw submits work to the rendering pipeline.
The vertex data for a draw call normally comes from a vertex buffer that is bound to the pipeline.
Even without any vertex buffer bound to the pipeline, you can generate your own vertex data in your vertex shader by using the SV_VertexID system-value semantic to determine the current vertex that the runtime is processing.
