Nice to see other open source CAD development being explored. BRL-CAD has had the pixdiff, bwdiff, and pixcmp tools for a very long time, for very similar purposes: pixdiff: https://manpage.me/index.cgi?q=pixdiff&sektio

Now this is awesome. Hope iHerb appreciates this as it should will lead to more sales through them. Scraping is always tricky. Love that you’ve included other nutritional facts. Would be cool to also incorporate review scores and/or

Very cool that it emulates the phosphor "burn" fading away like the original vector graphics hardware. You can see and play the real thing at The Strong National Museum of Play in Rochester, New York.

Boggles my mind when coders don't save everything they've ever written. It's easy to be a digital pack-rat without much consequence. That said, my first Java 1.02 programs from the 90's still compile and the old jars ru

I have the sources to "JHU UNIX" which were a direct fork of one of the earliest BSD's, though I don't recall hearing which. They were recovered off data tapes (and are still in an arcane raw binary format) from the lat

That's fair, but I figured the main page has it big and prominent right now, and does better to explain what GSoC is for anyone out of the loop.

This past week, orgs were announced for the 20th anniversary of the Google Summer of Code. Anyone new to open source (not just students anymore) can submit a proposal to remotely work on an open source project for a few months and get paid.

I'd be happy to host the site in perpetuity on one of our dedicated hosts (for free). Have hosted the sites for a number of notable open source communities for decades.

Not quite in the same vein, but the patent for T-splines expires in 2024. Big news for 3D modeling systems.

Tcl's integrated for the long haul, but clock is ticking on Tk. Migration will take a while, but Qt GUI is in the works.

Not entirely true. As an explicit edit method, sure, but several of the big-name non-parametric (i.e., solid modeling) commercial CAD systems are fundamentally still CSG representation under the hood. They just hide it well, typically und

Well said! Like many open source communities, pandemic had a pretty significant impact, but development and releases are quite active. New release coming out in a few weeks introduces conversion support for 150 new geometry and terrain file

BRL-CAD has a very rich and ongoing development history that is not immediately obvious. [1,2] Heavily actively used by gov'ts as it has unique features like validated full shotline solid ray tracing -- granted, not a feature most kno

The topic has come up and been a point of discussion, especially developing something akin to the ACIS or Parasolid kernels, but open source. In many areas, BRL-CAD's capabilities far exceed what OpenCascade provides, particularly w.r

The two main graphical applications, MGED and Archer, are both Tcl/Tk so what you're seeing is Tk. Newer GUI work in development is Qt-based.

If someone were to come to the project with an interest in integrating CAM features, they would not be turned away. Closest has been having someone implement a BRL-CAD-to-gcode converter, which was actually incredibly well-suited to solid

Devs feel the same way. Modernizing the GUI has been years in development to get necessary infrastructure bits in place. Massive disruption with pandemic and migration to git, but GUI work is now back on top of the priority queue. Qt-bas

Your code refactoring project was important! Eliminating those sys calls, you fixed bad code and addressed security violations. You helped reduce maintenance costs which in turn helped with code auditing efforts You're always welcome

Like a lot of open source communities, participation ebbs and flows, and additional hands are needed to make and maintain distribution binaries for different platforms. The project has recently prioritized usability improvements and that&#

I've found glTF ( https://www.khronos.org/gltf/ ) to be quite simple. The entire format is encompassed in something like a dozen entity types. Nice visual overview here: https://github.com/Khron

Happy Birthday to one of the most awesome but unfortunately named open source projects...

Haha, yes, that is technically correct, and the best kind. I probably should have qualified with an ambiguous "modern version control" or simply said it predates "RCS" (1982). There's actually some indications BRL-

Just a point of clarity, BRL-CAD now also supports BREP and is technically a hybrid modeling system. CSG and hierarchical relationships still underpin, but a lot of effort was invested in BREP support over many years. There was already ext

Another fun fact, BRL-CAD was started by Mike Muuss, author of the 'ping' networking tool. Brilliant computer scientist. Also, while it's evolved, the codebase predates nearly everything .. ansi c, c++, tcp/ip, opengl,

It's both a social and technical issue. For the prior, OpenCAx Association was created specifically to encourage and even sponsor OSS coordination. It's still in formation, but it's purpose has been to help underpin Google S

Your comment is incredibly insightful, more than many people will realize. Case in point, BRL-CAD has had more than 450 years of full-time effort invested, tens of millions with development spanning over four decades. However, that investm
