vtk 7.0 multipass rendering framework not working on iOS
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
It requires vtkFramebufferObject in case of using multipass rendering. When using vtkFramebufferObject, fbo.startNonOrtho() or fbo.createDepthBuffer() would call glRenderbufferStorgage(), which is not compatible with iOS stardard, thus would make multipass rendering framework in vtk not working on iOS. the error message is like this : vtkFrameBufferObject: failed at glRenderbufferStorage 1 OpenGL errors detected 0:(1280) invalid enum.
