Changes ModifierInstruction.(KMVERTEXBUFFDESC Structure)

Prototype declaration:


KMSTATUS KMAPI
kmChangeContextModifierInstruction(
        IN OUT  PKMVERTEXBUFFDESC   pVertexBuffDesc,
        IN      KMDWORD             dwModifierInstruction
);

Description:

This function changes the rendering parameter ModifierInstruction 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.

dwModifierInstruction(input)
        This parameter specifies the ModifierInstruction setting.
