Interpolated field slice: slice change with radio buttons
AVS Field Reader -> Interpolated Field Slice -> Viewer 3D
Read bluntfin.fld with AVS Field Reader. Connect Interpolated Field Slice. By default there appears an xy-slice.
Try to change the slice using the yz- or xz-slice buttons. In most cases the slice is shown in xy-plane by mapping the values. The exact slice appears not until slice resolution is changed.
