[vtk-developers] [vtkusers] 3D line and coordinate system

[Pengdong Xiao]

Hi Yumin,

Thank you very much for your e-mail. After I change the following:

display1[2] = 0 ;

the problem still exists. After I click mouse, a line will be drawn, but it isn't perpendicular to the screen; and each time the length is different. Any other suggestions? Many thanks.

Best regards,
Pengdong
