D3DLOCKED_BOX

Describes a locked box (volume).

typedef struct _D3DLOCKED_BOX {
    INT                 RowPitch;
    INT                 SlicePitch;
    void*               pBits;
} D3DLOCKED_BOX;

Members

RowPitch

Byte offset from the left edge of one row to the left edge of the next row.

SlicePitch

Byte offset from the top-left of one slice to the top-left of the next deepest slice.

pBits

Pointer to the beginning of the volume box. If a D3DBOX was provided to the LockBox call, pBits will be appropriately offset from the start of the volume.

Remarks

Volumes can be visualized as being organized into slices of width x height 2-D surfaces stacked up to make a width x height x depth volume. For more information, see Volume Texture Resources.
