[vtkusers] Surface rendering of multiple objects

[yanqiao zhu]

Hi Christian,

I downloaded the code and data you provided in the previous post and changed
the code as you told in this post by adding lut->SetTableRange(0.0, 7.0);
and changed mapper->SetScalarModeToUsePointData(); to
mapper->SetScalarModeToUseCellData(); But what I get after running the
program is shown in the image 
http://vtk.1045678.n5.nabble.com/file/n4636845/result.png , which is far
from your result. So I am wondering maybe something is wrong. Could please
check it. The source code is also attached. 

Thanks very much!
Best,
Yanqiao Zhu
