I disagree. The current behavior looks fine to me.
1. Changing the range to make the bottom part visible is a bad idea. A better way to get the same effect is to raise the opacity of the leftmost control point a bit. 2. ParaView makes no effort to build a transfer function. The default is going to be insufficient most of the time. You are expected to have to edit the transfer function for your particular data. Nevertheless, as a static default setting, it works better than any other I have seen. 3. Rendering the empty space as empty makes sense to me. Much of the time the space is really empty. Even if it is not, the region clearly has no information as it has the constant minimal value. Might as well get it out of the way to see the interesting stuff. 4. If you don't like that, you can set whatever transfer function you want to be the default. Raise up the left control point and hit "Make Default". -Ken On 7/30/09 11:40 AM, "David Doria" <[email protected]> wrote: On Thu, Jul 30, 2009 at 12:54 PM, Renato Elias <[email protected]> wrote: You just need to play a little bit with the transfer function editor ;o) http://www.nacad.ufrj.br/~rnelias/paraview/vr.jpg <http://www.nacad.ufrj.br/%7Ernelias/paraview/vr.jpg> Regards Renato. Hm, it seems that if you rescale the data range to [-1,10] instead of [0,10] you can then see the "empty" space in the cube. Shouldn't that be the default? i.e. why can you not see anything when it is exactly equal to the lower bound of the color scale? Shouldn't it snap anything below that to the lowest color?
