<br><br>Hi <br><br><span lang="en"><span>I can get bounds of an actor to know that </span><span>it is located in a</span> <span>range of</span> <span>situations</span> <span>in</span> renderwindow<span>.</span> <span>Course</span> <span>is</span> <span>a</span> object like cube,<br>
</span><br><span lang="en"><span>But</span> <span>if the</span> <span>object</span> <span>is</span> <span>irregular</span> <span>organ</span> <span>then</span> <span>draw</span> <span>a bounding box</span> <span>around</span> <span>the object</span></span><span lang="en"><span lang="en">, <span>it</span> <span>would be a</span> <span>black background</span> <span>(assuming</span> <span>the object</span> <span>is</span> <span>white</span><span>) </span></span> <span>in</span> <span>some</span> <span>situations.</span><span></span><br>
<span></span><br><span>In fact I want to know </span></span><span lang="en"><span><span lang="en"><span><span lang="en"><span><span lang="en"><span>which </span></span></span></span>positions, </span></span></span></span><span lang="en"><span><span lang="en"> <span>the value of them is zero(black)</span></span> in this bounding box of </span> <span>the</span> <span>actor</span></span>,<br>
(like the some voxel of it is zero )<br> <br>now Do I use from what command in vtk?<br><br>thanks alot<br><br><br>
