Statics Posted October 16, 2015 Share Posted October 16, 2015 Hi, I was wondering if there was anyway to adjust the thickness of a line. I'm trying to make some lines stand out more than others. I've been told to use a cylinder by some people in another post, but cylinders have issues when working with paths and when cameras are close to them. right now the way I'm doing it is by putting several lines close to each other, but that looks messy and isn't quite perfect. Thanks for any help!! Quote Link to comment Share on other sites More sharing options...
JCPalmer Posted October 16, 2015 Share Posted October 16, 2015 I saw that there was a line vertex shader today. If you look at it, it certainly looks like at the GPU level, width is passed/considered.https://github.com/BabylonJS/Babylon.js/blob/master/src/Shaders/line.vertex.fx It is an open source system. Start digging in the .TS or .JS files, and you can probably answer your own question. Quote Link to comment Share on other sites More sharing options...
GameMonetize Posted October 16, 2015 Share Posted October 16, 2015 You can also consider creating tubes depending on the number of lines you want Quote Link to comment Share on other sites More sharing options...
Wingnut Posted October 16, 2015 Share Posted October 16, 2015 We are thinking alike, DK... so, you might want to see a doctor. http://playground.babylonjs.com/#Z1SIC#1 But there could be ANOTHER way to make fat lines. Drum roll please... http://playground.babylonjs.com/#1IYSYD ta-da! errr... something. Here's some more mad fun.

Wingnut Posted October 17, 2015 Share Posted October 17, 2015 Hmm, the tube demo (previous post) is suddenly failing... for me... today... at these temperatures. Ok, WHO broke the magic etch-o-sketch? Quote Link to comment Share on other sites More sharing options...

captainleighwalker Posted June 27, 2018 Share Posted June 27, 2018 Sorry I was referring to this method http://playground.babylonjs.com/#1IYSYD#1 I have a big smooth radius line so I thought a tube was a bit over the top. Quote Link to comment Share on other sites More sharing options...

Pryme8 Posted June 27, 2018 Share Posted June 27, 2018 Maybe... at least a good solution for thick lines that are on a singular plane. hmmm I just actually realized this is being overthought... and I was about to do some fancy ribbon method that was going to be overkill... http://playground.babylonjs.com/#Z1SIC#10 the tube solution with a custom shader set should do it. http://playground.babylonjs.com/#Z1SIC#12 Quote Link to comment Share on other sites More sharing options...

dbawel Posted June 28, 2018 Share Posted June 28, 2018 @Statics Good point... Why can't I change the line width in the scene below. I understand your frustration; although the babylon devs and contributors are doing their best to maintain a cohesive framework.. http://www.babylonjs-playground.com/#H7VAZR#1 DB Quote Link to comment Share on other sites More sharing options...

I use the "line2d" function too to display line segments with the same thickness. A very awesome and useful function ?!!! In some situation, when the current line segment and previous line segment nearly overlap, the lines (better: the corners) will get "oversized". In my screenshots i move the red point in the arrow direction and the lines/corners will get "oversized". How can i avoid this? Best regards, Tim Edited October 17, 2019 by TimT77 Change second image to better display the problem Quote Link to comment Share on other sites More sharing options...

TimT77 Posted October 22, 2019 Share Posted October 22, 2019 Hi all! I've fixed my problem (previous post) with setting the angle to "3.141". This creates always "rounded" corners. Greetings! Tim Quote Link to comment Share on other sites More sharing options...
