And this is how you do that in OpenGL: In the vertex shader, you supply vertex position and normal as you usually do, but now you also have a vertex attribute for the transformation like this: in mediump vec4 position; in mediump vec4 surfacenormal; in mediump mat4 trf; fnsw competition rulesWebHow 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. greenways agatha christie home
