[Ves] Sample VES Application in iOS

[Aashish Chaudhary]

Have a look at this test:

http://vtk.org/gitweb?p=VES.git;a=blob;f=src/kiwi/Testing/TestTexturedBackground.cpp;h=fe6959f29159664c7c726cc72f1b26d078424278;hb=refs/heads/master


Specially this function:

oid loadData(const std::string &filename, const std::string &imageFilename)

 {

   this->unloadData();
