.Bold { font-weight: bold; }
.Title { font-weight: bold; font-size: 18px; color: #cc3300; }
.Code { border: #8b4513 1px solid; padding-right: 5px; padding-left: 5px;color: #000066; font-family: 'Courier New' , Monospace;background-color: #ff9933; }</style>Dear friends,<br />
<br />
I applied vtkPointPicker to pick a point in screen (pixel) coordinates from a dataset. The data are a series of CT images. However, there are two problems: 1) the z value is always 0, no matter in which slice I pick a point; 2) the x and y values are different from other programs like MITK. I compared the values of the same point between my program and MITK. MITK shows that the z value changes according to which slice you are in to pick a point.<br />
<br />
Here is my code:<br />
<br />
<font color="#0000ff" size="2"><font color="#0000ff" size="2">
<p>double</p>
<p> </p>
<p>std::cout <<</p>
</font></font><font size="2">index[3];</font><font color="#0000ff" size="2"><font color="#0000ff" size="2">this</font></font><font size="2">->Interactor->GetPicker()->GetSelectionPoint(index);</font><font color="#a31515" size="2"><font color="#a31515" size="2">"Index: "</font></font><font size="2"> << index[0] << </font><font color="#a31515" size="2"><font color="#a31515" size="2">" "</font></font><font size="2"> << index[1] << </font><font color="#a31515" size="2"><font color="#a31515" size="2">" "</font></font><font size="2"> << index[2] << std::endl;</font><br />
