[vtkusers] New to VTK (OpenGL2 Line Stipple)

Unfortunately LineStipple was removed in OpenGL version 3.1 about six years
ago (along with LineWidth sort of) and there is no replacement in OpenGL. It
has never been in OpenGL ES for Android/iOS to my knowledge. Currently in
VTK it is not supported on the OpenGL2 backend. At some point we could try
to add it back in fully or partially with our own implementation just not
sure how high of a priority it is relative to everything else.

Thanks
Ken

Subject: [vtkusers] New to VTK (OpenGL2 Line Stipple)

Hi Everyone,

   I’m new here. I was wondering if anyone here could help me out. The
project I’m working on at my workplace involves the use of VTK, and we are
currently planning on transitioning from the fixed-function pipeline to the
OpenGL2 (I believe it’s still beta). However, I noticed on running a test
with OpenGL2 as the renderer the previous Line Stipple we used to have when
rendering our model / content is now replaced with straight Lines. My
question is was this a change within VTK or what, if so is there a way to
get back the Line Stipple. Thanks
