glx | A WebGL base framework | Graphics library

Please consider the snippet below. It plots a set of spheres connected by some segments. The function to draw the smooth spheres comes from the discussion at

How to increase smoothness of spheres3d in rgl

What puzzles me is the following: when I zoom in/out the RGL plot, the spheres and the segments behave differently. In particular, if I zoom in, the segments look rather thin with respect to the spheres, whereas they look really wide when I zoom out.

Is there a way to correct this behavior, so that the proportion between the spheres and the segments is always respected regardless of the zoom level? Thanks a lot

I am trying to create a Shiny app that displays an RGL visualisation (which is nothing else than a set of polished sticks and spheres). Please have a look at the code for the visualisation below

I wrote a bunch of visualization functions in my python3 library using Mayavi. I am not very familiar with this library, nor am I with testing visualizations using python.

Ideally, I would just like the visualization code to generate some graphics on disk, I don't care too much about popping up windows (although I'm not sure to understand if Mayavi can work properly without popping such windows).

Anyway, my code works on local, but when I push it on develop, CircleCI fails at running the tests with the following error:

I started working on a Python 3.9 QT5 program about a year ago on Ubuntu 20.04 (Focal) and then let it slide. Today I tried to work with it on another computer, which runs Ubuntu 21.10 (Impish) and there seems to be an issue with PyQt somehow.

I have CA certificates files in "greenlock.d/live/URL_PATH/". It's expiration date is Aug 2022.

But I want to renew them right now to check whether they are renewing or not. Please suggest me how can I renew them at any time?

I have tried number of solutions like:

• Tried Some commands
• Changing renewal time ("renewAt") in "greenlock.d/config.json"

app.js

I installed pygame using: pip3 install pygame

I'm unable to do any work and get failed request error message.

i was containerizing my .Net + React.js application but during the process I have encountered an unexpected error. I got myself acquainted with similar posts but none of the solutions solved my problem. Since the build log is quite long I have placed in pastebin:

The dockerfile which I am using comes from the official documentation, and that's why it comes to me as a surpise that it does not work:

The Dockerfile itself:

I have read and pieced multiple projects together in order to create an x11 window with open gl working, with the preinstalled GL/gl.h and GL/glx.h. The problem I get is that the triangles I want to draw to the screen does not show. What I think is that I have not setup any projecting parameters etc, or that the triangles doesn't get drawn to the space I want to draw to.

I do get a window and I am able to setup xevents that triggers after I have subscribed with eventmasks. Pressing 'esc' key will trigger an event which will in the end call Shutdown() and break the loop, free up x11 and gl stuff, and lastly exit the program. So the only thing that doesn't work is the drawing to screen stuff which basically is the main point of my program.

How can I resolve this?
