[vtkusers] Picking in DICOM series

[Liu_tj]

As there are several kind of coordinate system in VTK, you need to check the check values are world, viewport, normalized viewport coordinate.


Perhaps you can post your code here and the forum guys can help you.


Thanks

Hi Liu Peng,
I have tried different dicom samples of different resolutions.When i use a sample of 320*320,the max value that i get from the picker is 150*150,and this too varies with samples.when i tried with another 320*320 sample max value that i got was 160*160.


Thanks

How do you know the values are wrong?

Hi,


I've been trying to implement a Picker in the OnMouseMove of a custom vtkinteractorstyleImage,so that i can get the pixel coordinates of an image while hovering over an image.Now I've tried both the Point Picker and the Prop Picker to do so,,both gives the coordinates but the problem is that the values are not correct.So am i missing anything?
and i am new to vtk,So please help me out


Thanks in Advance
