You can get the range of supported line widths with: GLfloat lineWidthRange [2]; glGetFloatv (GL_ALIASED_LINE_WIDTH_RANGE, lineWidthRange); lineWidthRange [1] will then be the maximum supported line width. Based on table 6.18 of the spec, the minimum allowed value for this limit is 1. WebHow to Draw Thick Mesh Lines. Tom Goddard August 13, 2024 Modern OpenGL core profiles don't offer line widths except for 1 pixel. On retina or high-dots-per-inch 4K displays these lines are very thin and faint and two pixel width lines would be better. Here I looked at a few ideas to provide mesh lines greater than 1 pixel wide.
