D3DPRIMITIVETYPE enumeration
Defines the primitives supported by Direct3D.
Syntax
typedef enum D3DPRIMITIVETYPE {
D3DPT_POINTLIST = 1,
D3DPT_LINELIST = 2,
D3DPT_LINESTRIP = 3,
D3DPT_TRIANGLELIST = 4,
D3DPT_TRIANGLESTRIP = 5,
D3DPT_TRIANGLEFAN = 6,
D3DPT_FORCE_DWORD = 0x7fffffff
} D3DPRIMITIVETYPE, *LPD3DPRIMITIVETYPE;
Constants
-
D3DPT_POINTLIST
-
Renders the vertices as a collection of isolated points. This value is unsupported for indexed primitives.
-
D3DPT_LINELIST
-
Renders the vertices as a list of isolated straight line segments.
-
D3DPT_LINESTRIP
-
Renders the vertices as a single polyline.
-
D3DPT_TRIANGLELIST
-
Renders the specified vertices as a sequence of isolated triangles. Each group of three vertices defines a separate triangle.
Back-face culling is affected by the current winding-order render state.
-
D3DPT_TRIANGLESTRIP
-
Renders the vertices as a triangle strip. The backface-culling flag is automatically flipped on even-numbered triangles.
-
D3DPT_TRIANGLEFAN
-
Renders the vertices as a triangle fan.
-
D3DPT_FORCE_DWORD
-
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
Remarks
Using Triangle Strips or Triangle Fans (Direct3D 9) is often more efficient than using triangle lists because fewer vertices are duplicated.
