Hello everyone,
I am working on a project in which i need to render linepatterns( dashed lines)
First of all the glLineStipple is depreciated and i don’t want to use that.
I went through multiple articles:
→ http://jcgt.org/published/0002/02/08/paper.pdf
→ opengl - Dashed line in OpenGL3? - Stack Overflow
→ glsl - glLineStipple deprecated in OpenGL 3.1 - Stack Overflow
I am somewhere confused with which implementation should i follow.
Please Help and suggest me what and how (any possible idea) should i use which is according to my requirements and is doable.
My requirements–
1–> I need to apply line pattern on individual line segments(GL_LINES) and polygon also…(GL_LINE_STRIP and GL_LINE_LOOP)
2–> The pattern (to be used) stored in CPU (is in an array/vector) is like this…
example A= {20}
dash(20)->||gap(20)->|| dash(20) ->||gap(20) ->|| dash(20) ->||gap(20) ...so on
like this…
Example B= {20,10}
dash(20)->gap(10)->|| dash(20) ->gap(10) ->|| dash(20) ->gap(20) ...so on
like this… 
Example C={20,10,5}
dash(20)->gap(10)->dash(5)|| gap(20) -> dash(10) ->gap(5)||dash(20)->gap(10)->dash(5)
…so on like this… 
means alternatively dash and gap (always starting from dash…)
NOTE: The above images are rendering by cairo graphics… I need to implement the same using pure OpenGL
Please Help
