Jit.gl.isosurf + matrixoutput 1

In the example jit.gl.isosurf-mov, I'd like to enable matrixoutput of the isosurf object, smooth the data, and render. As the first step toward doing this, it would seem like I should be able to enable matrixoutput and patch directly into the render object to get the same results as having the two connected by render context. That doesn't seem to work. There are a lot of factors to consider - scaling, lighting etc. In a general sense, is the matrix out of the isosurf object supposed to be able to generate a matrix that can be rendered with just the render object, or am I skipping something?
