Query Xform at certain time?

[Anonymous]

Hi,

A simple question here,

we wrote a script that samples the worldspace Xform position based on a frame range using the cmds.currentTime command to indicate the frame we want to sample.

all works well, but we are looking for a way to speed up the sampling so we can skip the viewport evaluation for every frame and still sample the correct values. 

in other words we are looking for a 'time' atribute in the x form command 🙂 

what would be the easyest way around this problem?

thanks.

Hi there. 

I use c++ API for it... 

but you can write it on Python too, I guess

 MStatus WrightBoneAnim(MDagPath &bonePath, MMatrixArray &mArr, int sf, int ef) // sf - start frame, ef - end frame 
{                                                                               // mArr - array of matrices for object
                                                                                // in given time range


	MStatus status;          
	
	mArr.clear();
	MTime time_1;
	time_1.setUnit(MAnimControl::currentTime().unit());
		for (int i = sf; i <= ef; i++) {

			time_1.setValue(i);
			status = MAnimControl::setCurrentTime(time_1);
		
			CHECK_MSTATUS_AND_RETURN_IT(status);
		

			mArr.append(bonePath.inclusiveMatrix());
			

		}
		
		return MS::kSuccess;
	
}
