<div dir="ltr">Good morning,<div><br></div><div>I have just upgraded my model from testing algorithms on the unit sphere (x,y,z in [-1,1]) to a model that computes in physical units relevant to an Earth-sized sphere, so that now x,y,z span [-6.371e6, 6.371e6]. While ParaView handles this change with no problem, my vtk codes no longer show the polydata -- all I get upon rendering is a blank field. </div>
<div><br></div><div>I have tried changing the camera positions to account for the now much larger physical space, and I can verify that the vtkPolyDataReaders are working by displaying the number of cells. I suspect it's an issue with coordinate systems, but then changing the camera position and view up should have worked. </div>
