MFnNumericData::k4Double

#1

I can create a MAYA_double4 type attribute:

MFnNumericAttribute fnNumAttr;
mBboxAttr = fnNumAttr.create("bBox", "bBox", MFnNumericData::k4Double, 0.0, &stat);

But if I want to work with it, I have only up to double3 functions?

MStatus stat;
MFnDependencyNode depNode(mHW->thisMObject(), &stat);
MPlug bboxPlug = depNode.findPlug(mHW->mBboxAttr, true, &stat);
MDataHandle data = bboxPlug.asMDataHandle();
//MAYA_double4 &v4 = data.asDouble4(); // no such method
MAYA_double3 &v3 = data.asDouble3(); // fine, but what about the fourth element?
#2

how is about:

std::vector<double> val(4);
MFnNumericData numDataFn(thePlug.asMObject());
numDataFn.getData4Double(val[0], val[1], val[2], val[3]);

(i don’t have maya around to try)

#3

That would do.
Thanks
