Demo1: data generation failed

[ttyang1018]

Hi there,

I sucessfully built the whole library. But when I try out the demo1: Training set data generation. The generated image seems not correct.

The generated image are all blank image or just only a small part of the target.

Take ant.ply as example. The image only contain its Tentacle...

When it comes to app.ply, the images are nothing, like the following pics

any idea?

By the way: my vtk version is 7.0
