WebI'd try drawing the filled mesh first, then set the depth testing mode to GL_LEQUAL and drawing the wireframe. Set the depth testing mode back to GL_LESS before rendering the rest of the meshes. This will give the wire-frame priority whenever the depth values are equal to the previously drawn depth values. 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.
