This enumeration defines the primitives supported by Microsoft® Direct3D Mobile®.
Syntax
typedef enum _D3DMPRIMITIVETYPE {
D3DMPT_POINTLIST = 1,
D3DMPT_LINELIST = 2,
D3DMPT_LINESTRIP = 3,
D3DMPT_TRIANGLELIST = 4,
D3DMPT_TRIANGLESTRIP = 5,
D3DMPT_TRIANGLEFAN = 6,
D3DMPT_FORCE_ULONG = 0x7fffffff,
} D3DMPRIMITIVETYPE;
Elements
- D3DMPT_POINTLIST
Renders the vertices as a collection of isolated points.
- D3DMPT_LINELIST
Renders the vertices as a list of isolated straight line segments. Calls using this primitive type fail if the count is less than 2 or is odd.
- D3DMPT_LINESTRIP
Renders the vertices as a single polyline. Calls using this primitive type fail if the count is less than 2.
D3DMPT_TRIANGLELIST
Renders the specified vertices as a sequence of isolated triangles. Each group of three vertices defines a separate triangle.Backface culling is affected by the current winding-order render state.
- D3DMPT_TRIANGLESTRIP
Renders the vertices as a triangle strip. The backface-culling flag is automatically flipped on even-numbered triangles.
- D3DMPT_TRIANGLEFAN
Renders the vertices as a triangle fan.
- D3DMPT_FORCE_ULONG
Forces the compiler to interpret the enumeration as a ULONG value. This value is not used directly in Direct3D Mobile programming.
Remarks
Because fewer vertices are duplicated when triangle strips or triangle fans are used, using them is more efficient than using triangle lists.
