Well, I saw the fix you commited, but I still see my "slots" in the
data. I've attached a screenshot where you can see it on the right side.<br><br><div><span class="gmail_quote">On 7/13/05, <b class="gmail_sendername">Lisa Avila</b> <<a href="mailto:lisa.avila@kitware.com">lisa.avila@kitware.com

Oh yeah, plenty of ideas. Sounds like I didn't handle that case very
well! :-) I'll try to get the fix in tomorrow. (Hmm, after midnight -
later today I guess)<br><br>
The problem probably wasn't there before - I added extra code to make
sure I absolutely never ever step outside the volume (the old code was
letting some round-off errors in the conversion to fixed-point cause the
last step to potentially be out of the volume) but I guess I was a bit
too aggressive! Should be a simple fix....<br><br>

When rays are perfectly parallel to an axis aligned plane (eg: the planes
of the dataset are parallel to the viewing direction), I get black.
So as the volume rotates, you can see "between" the slices as
each coordinate plane comes parallel to the viewing direction. it
never did this before, and i'm pretty sure it's not supposed to be doing
it now. My dataset is a Structured Points dataset. I thought
that "between" the points would simply be interpolated or
Nearest Neighbored (depending on the mapper configuration) to fill in
between them. <br><br>
any ideas?<br><br>
