Changes DCalcControl.(KMVERTEXBUFFDESC Structure)

Prototype declaration:


KMSTATUS KMAPI
kmChangeContextDCalcControl(
        IN OUT  PKMVERTEXBUFFDESC   pVertexBuffDesc,
        IN      KMINT32             nParam,
        IN      KMBOOLEAN           bDCalcControl
);

Description:

This function changes the rendering parameter DCalcControl that was registered in pGlobalParam
from pVertexBuffDesc by kmSetVertexRenderState/kmSetStripHead.
The following is a list of supported VertexType:

Note:
    This function changes some of pGlobalParam from pVertexBuffDesc before starting
    a strip in response to kmStartVertexStrip.  Operation is not guaranteed if the
    rendering parameters are not registered from pVertexBuffDesc to pGlobalParam
    within the same pass beforehand.

VertexType00 VertexType06 VertexType12
VertexType01 VertexType07 VertexType13
VertexType02 VertexType08 VertexType14
VertexType03 VertexType09 VertexType15
VertexType04 VertexType10 VertexType16
VertexType05 VertexType11 VertexType17
Parameters:
pVertexBuffDesc(input/output)
        This parameter is a pointer to KMVERTEXBUFFDESC.

nParam(input)
        This parameter specifies the parameter for update.
            KM_IMAGE_PARAM1     parameter 1
            KM_IMAGE_PARAM2     parameter 2

bDCalcControl(input)
        This parameter specifies the DCalcControl setting.
            KM_TRUE    :   DCalcControl is valid.
            KM_FALSE   :   DCalcControl is not valid.
