source:points target:mesh

I know I can use regmm with source is mesh and target is points.
But I want soruce is points, targte is mesh. When I do this, there is a bug:
regmm: /usr/local/include/eigen3/Eigen/src/Core/Redux.h:413: typename Eigen::internal::traits::Scalar Eigen::DenseBase::redux(const Func&) const [with BinaryOp = Eigen::internal::scalar_sum_op<float, float>; Derived = Eigen::Block<const Eigen::Matrix<float, -1, 3, 1, -1, 3>, -1, 1, false>; typename Eigen::internal::traits::Scalar = float]: Assertion `this->rows()>0 && this->cols()>0 && "you are using an empty matrix"' failed.
Now ,I want to know whether it's source can be points and target is mesh.
Thank you.

Now I know this can do.I ingore that points supports xyz format.I try it. when it's the number of points is 209,it cost about 1.8s.Now I try 10943,it is very slow.
