Description T.Kiuchi 2018-05-16 01:07:19 UTC
Anti alias (GL_LINE_SMOOTH) does not work when drawing lines using Shader in OpenGL.
As a result of our investigation, the context in which MSAA (MultiSampleAntiAliasing) is enabled, Then It seems that the anti-aliasing will work if you create it.

So the question is how could we make the anti-aliasing to work under MSAA disable mode?

For your reference, if you use AMD driver to run it, The anti-aliasing function works well even when MSAA is disable.
