The angles and size of the generated image-3d point cloud

[ccxi1008]

I input this pictuer which is viewed from the front view. But got the result which is defaultly viewd from a strange agnle and Can't change it to defaultly viewed from the same view as the input image. And I rendered it in a random view it looks so close,even like I'm in the teapot.

How can I get the front-horizontal-view result？And how can I control the size of the point-cloud or the distance I'm away from?
