OpenCV-"Homogeneous coordinates are not supported" when using cvProjectPoints2

"OpenCV Error: Bad argument (Homogeneous coordinates are not supported ) in unknown function, file ......\modules\calib3d\src\calibration.cpp, line 826"

I think I'm getting this error when passing the following matrix into cvProjectPoints2() function

CvMat *dstPoints2D = cvCreateMat (4, 1, CV_32FC3);

cvProjectPoints2(srcPoints3D,rotation,translation,intrinsic_matrix,NULL,dstPoints2D);

I'm using OpenCV 2.3.0

Full code: http://pastebin.com/TYthn6Nt

Thanks in advance.

The output needs to be two channels. Change the declaration to CvMat *dstPoints2D = cvCreateMat (4, 1, CV_32FC2); and you won't get the error.
