Just wanted to share my latest WebGL experience...

Gl line width is deprecated, you should use a proper quad mesh.
Then just stretch it out for the length/width of the line

Edit: I should also mention quads are not supported so you need to make the quad out of 2 triangles. 😜

@hexc you fkn wot?

This seems to fit perfectly in overall web development and standards. You have to love consistency.

It's old deprecated functionality and for good reason, there's no reason why a modern graphics card would need hardware to draw a thick line when polygon processing is fast enough that you can just use two tris instead.
Actually, a lot of the more 2D parts of the OpenGL standard are going out of scope, reflecting trends in the graphics hardware industry. When you use OpenGL you're also using a lot of historical baggage, this is one big reason why Vulkan was made.

@hexc @RememberMe Actually i use lines to draw bounding box wire frames so a width of 1px is okay for now... but still.

I don't think there's a need to erase this handy feature, especially if you have to upload much more vertex data in order to render a quad. For debugging purposes, i want the smallest possible bandwidth - 3 times the data per drawn line is not really a good option.

Besides that it's a great example for downward compatibility (setting limits to 1 instead of just erasing the function) and a beautifully crafted sentence by some MDN member to describe the deprecation =D

Need more width?
for(uint16_t i=0;i<WIDTH;i++)
drawHorizontalLine(x, y+i, length);

//Same for vertical lines

(For those who didn't caught it: It's a joke)

@LuxARTS Perfect! Then i force my userbase to buy nVidia's new RTX cards and utilize the higher ray drawing performance by casting 2D rays... That's how raytracing works, isn't it? =D

Because 3D drawing is not the same as 2D. Need more thick line? draw polygons.

@Pogromist welp, that's boolshit. The lines are in the 3D space, too. In the end it's all just passed to the rasterizer, which is obviously a 2D thing. Even triangles are simply mapped into a 2D space and rasterized. They used to have this feature and decided to limit it to 1px thickness. Maybe because nobody used it or to make room for other features - I don't know.

@irene some pixels on a screen, actually =D

I could also describe a 1px thick line as a rectangle btw. So why offer line drawing in the first place?
