View the official Windows Driver Kit DDI referenceNo description available.
The DrawPrimitive function draws nonindexed primitives in which the Microsoft Direct3D runtime has not transformed the vertex data.
hDevice [in]A handle to the display device (graphics context).
unnamedParam2pData [in]
A pointer to a D3DDDIARG_DRAWPRIMITIVE structure that describes the primitive to draw.
unnamedParam3pFlagBuffer [in]
A pointer to a 32-bit value that contains triangle-edge flags, which are used only during line-fill mode. The first three bits (0/1/2) of the 32-bit value specify how the three edges of the corresponding triangles are rendered. If a bit is set to 1, its associated triangle edge is rendered; otherwise, the edge is not rendered.
If the pointer is NULL, the user-mode display driver should use its fast path to draw primitives.
DrawPrimitive returns S_OK or an appropriate error result if the primitive is not successfully drawn.
When the Microsoft Direct3D runtime specifies triangle-edge flags in the value that the pFlagBuffer parameter points to, the runtime also specifies to draw one or more triangles (that is, the runtime specifies the D3DPT_TRIANGLEFAN value in the PrimitiveType member and from 0x00000001 to 0xFFFFFFFF in the PrimitiveCount member of the D3DDDIARG_DRAWPRIMITIVE structure that the pData parameter points to).
