D3DDEGREETYPE

Defines the degree of the variables in the equation that describes a curve.

typedef enum D3DDEGREETYPE
{
    D3DDEGREE_LINEAR = 1,
    D3DDEGREE_QUADRATIC = 2,
    D3DDEGREE_CUBIC = 3,
    D3DDEGREE_QUINTIC = 5,
    D3DCULL_FORCE_DWORD = 0x7fffffff,
} D3DDEGREETYPE, *LPD3DDEGREETYPE;

Constants

D3DDEGREE_LINEAR

Curve is described by variables of first order.

D3DDEGREE_QUADRATIC

Curve is described by variables of second order.

D3DDEGREE_CUBIC

Curve is described by variables of third order.

D3DDEGREE_QUINTIC

Curve is described by variables of fourth order.

D3DCULL_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

The values in this enumeration are used to describe the curves used by rectangle and triangle patches. For more information, see D3DRS_CULLMODE.
