D3DINDEXBUFFER_DESC

Describes an index buffer.

typedef struct _D3DINDEXBUFFER_DESC {
    D3DFORMAT           Format;
    D3DRESOURCETYPE     Type;
    DWORD               Usage;
    D3DPOOL             Pool;
    UINT                Size;
} D3DINDEXBUFFER_DESC;

Members

Format
Member of the D3DFORMAT enumerated type, describing the surface format of the index buffer data.
Type
Member of the D3DRESOURCETYPE enumerated type, identifying this resource as an index buffer.
Usage
Combination of one or more of the following flags, specifying the usage for this resource.
D3DUSAGE_DONOTCLIP
Set to indicate that the index buffer content will never require clipping.
D3DUSAGE_RTPATCHES
Set to indicate when the index buffer is to be used for drawing high-order primitives.
D3DUSAGE_NPATCHES
Set to indicate when the index buffer is to be used for drawing N patches.
D3DUSAGE_POINTS
Set to indicate when the index buffer is to be used for drawing point sprites or indexed point lists.
D3DUSAGE_SOFTWAREPROCESSING
Set to indicate that the buffer is to be used with software processing.
D3DUSAGE_WRITEONLY
Informs the system that the application writes only to the index buffer. Using this flag enables the driver to choose the best memory location for efficient write operations and rendering. Attempts to read from an index buffer that is created with this capability can result in degraded performance.
Pool
Member of the D3DPOOL enumerated type, specifying the class of memory allocated for this index buffer.
Size
Size of the index buffer, in bytes.
