tried HDMake .... -xmlcntrsphere filename.xml 0 180 and it didn't like the 180 parameter. HDMake .... -xmlsphere filename.xml 0 360 0 180 seems to be doing something
The arguments for -xmlcntrsphere are "-xmlcntrsphere filename.xml fov" (see http://research.microsoft.com/ivm/HDView/HDMake.htm) it looks like you provided 3 arguments. I think -xmlcntrsphere filename.xml 180 will work.
