I have a Goldberg polyhedron that I have procedurally generated. I would like to draw an outline effect around a group of “faces” (let's call them tiles) similar to the image below, preferably without generating two meshes, doing the scaling in the vertex shader. Can anyone help?

My assumption is to use a scaled version of the tiles to write into a stencil buffer, then redraw those tiles comparing the stencil to draw the outline (as usual for this kind of effect), but I can't come up with an elegant solution to scale the tiles.

My best idea so far is to get the center point of the neighbouring tiles (green below) for each edge vertex (blue) and move the vertex towards them weighted by how many there are, which would leave the interior ones unmodified and the exterior ones moved inward. I think this works in principle, but I would need to generate two meshes as I couldn't do scaling this way in the vertex shader (as far as I know).

If it’s relevant this is how the polyhedron is constructed. Each tile is a separate object, the surface is triangulated with a central point and there is another point at the polyhedron’s origin (also the tile object’s origin). This is just so the tiles can be scaled uniformly and protrude from the polyhedron without creating gaps or overlaps.

Thanks in advance for any help!

EDIT:

jsb's answer was a simple and elegant solution to this problem. I just wanted to add some extra information in case someone else has the same problem.

First, here is the C# code I used to calculate these UVs:

Here is a piece of code taken from the seminal "A Pedagogical Implementation of the GSM A5/1 and A5/2 "Voice Privacy" Encryption Algorithms" by Marc Briceno, Ian Goldberg, and David Wagner:

I have a function which binds a passed function to a HTMLElement:

I am using react framework for designing a website. The website is well designed and complete . Now I see that my website is scrolling through y axis . I have seen work around like overflow:hidden but the screen design will be impacted because it has margin on top and bottom. Can anyone look into it and tell me answer?

App.js

I have a sample tbl_df that I am trying to find a solution to. I am trying to do the following at a high level. Compare the max score for a student in 2021 (based on which type count they have the most of) to their most recent result in that type in the most recent year before 2021. I'd like to use dplyr::filter but can't figure out how to filter properly to retain the tbl_df to get to my output.

In brief:

1. Group by full_name and choose the type row that has the max value in the count column for 2021
2. Choose the next most recent year for that same type

As you can see, since Eric Collins doesn't have a row in 2020, his most recent year is 2019, while the others have values in 2020.

Hey guys I am try to create click bottom that user can click it and animation restart as I understand it not possible and we need to destroy animation and readd it again. So I try this way at first

HTML

so I am trying to test a form which is implemented in react. When I submit a form through jest, I get a different event as when I submit the event through the browser.

The test I am using is this one:

So I'm currently doing Brad Traversys 50 projects in 50 days, but I wanted to do it built in Next.js with React for practice, as that's what I use at my job.

As you can see from me posting here, it's not going so well! I'm already running into road blocks.

I'm trying to create a set of cards, that when one is clicked, it expands out. Outside this, if there is a card already expanded, and another card is clicked, I need the previously expanded card to collapse, whilst the card currently clicked expands.

I'm currently trying to work off an active state, and passing that down to the Panel props, but obviously that just sets all the flex's to be the same and nothing happens. But when I try to define the active useState inside the Panel component, it works, but I can't then target the other active states in the other Panels, to set them to false.

What's the best way to go about this?

This question is based on the paper What Every Computer Scientist Should Know About Floating-Point Arithmetic by David Goldberg. In the section 1.2 Relative Error and Ulps (page number 8), the paper gives an equation to calculate error in, ULP (units in the last place):
