Hello vtkusers, I need your Knowledge, because I have a problem:<br><br>I am developing a tool for to calculate distances on a vtkImageData. Each distance is represented with a vtkLineSource, and a mapper2D and actor2D. this mapper2D uses a world system coordinates. I work with 2D because my framework use this system. Up to this point all that I have implemented run correctly. My problem appears when I want to draw the ends on a distance. I represent them with a vtkDiskSource, a mapper2D and a actor2D, each end of distance. Each mapper2D of the vtkDiskSources works like my distance system coordinate, this is with world system coordinate. Before to render each disk, I show what is his position and is equal to end of the distance, I want to say that the position of each disk is correct, I ask too what is the system coordinate of the distance and of each disk, and they are the same coordinate system. Though I am insure of the use of the same coordinate system and same position, the disks do not appear in supposed and correct position for that I wait.
<br>Somebody knows what is the problem? <br><br>if you want that I post my code, say me it.<br><br>Thaks a lot.<br> <br clear="all"><br>-- <br>.: Sergi Dote Teixidor :.
