In this blog post I wrote some notes about B-splines. There are however important classes of curves and surfaces that cannot be represented by piecewise-polynomials like circles, ellipses etc… NURBS[...]
In the previous blog post here I implemented BĂ©zier curves. There are other important structures that are used in computer graphics and I’d need those structures to define a domain[...]
While working on my sample IGA implementation here https://github.com/carlonluca/isogeometric-analysis, I found myself in need of defining and implementing the math structures used to define the domain and the solution space.[...]
It’s been some years since I completed my dissertation on FEM and Isogeometric Analysis, but I realised I never had the time to organise my code properly and archive it.[...]
Blog It’s been many years now since I started to use a Pi as a version control server. I recently even started to use it more heavily for my development,[...]
Calls to HTTP servers are very frequent nowadays, and JSON is frequently used when dealing with structured data. When I write applications in Java/Kotlin, I always use retrofit2 with gson[...]
I frequently create classes that I use as an interface to settings in my apps. Using a single class with accessors makes the code readable, safer and simple to maintain.[...]
There are some utils that I use in most of my Qt projects. I’m a bit fed up of copy-pasting those every time I need something, so I created a[...]
Raspbian Buster is out. It seems it updated gcc from version 6.3.0 (used for Stretch) to gcc version 8.3.0. This is not always needed, but I had a lot of[...]
Raspberry has a huge community that creates a considerable amount of material in a large number of projects. A relevant support for Yocto cannot therefore be missing for it. Months[...]
This was a good test for my cross toolchain with gcc 6.3.0 I uploaded some days ago: the new Qt 5.10.0 built with -march=armv8-a -mtune=cortex-a53 -mfpu=crypto-neon-fp-armv8 -mfloat-abi=hard, including POT for[...]
Raspbian Stretch is out for Raspberry Pi. I needed a cross toolchain with the same exact version used to build the system so I built my own. As I had[...]
This post is mostly for myself 🙂 In some cases, couldn’t find out why, but shared directories fail to mount in VMWare on Linux. In these cases, this is the[...]
At the moment I still don’t want to test custom firmwares or 64 bit arch builds, but I started to test a couple of new features: a new compiler from[...]
A few months back I decided to try to implement hardware decoding in WebKit. Unfortunately this task is always pretty long and complex for many reasons. I found the time[...]
A new version of Qt is out and some interesting changes are being developed. Interesting work was done on WebEngine. This package contains an experimental build of Qt 5.8.0-rc1 with[...]
So far, no real complains about POT 5.4.0-beta1 so I suppose it is sufficiently safe to consider it POT 5.4.0. Refer to this article for more info.[...]
This is a new binary package including the same content of POT 5.3.0-beta1 package, with some updates: new improvements in POT taken from omxplayer code; bump to ffmpeg 3.1; based[...]
The latest version of POT (5.3.0-beta1) implements some kind of buffering which makes it also possible to do some streaming. ffmpeg provides what is needed to work on protocols like[...]
This is an experimental version of POT that includes a few new features. The driver now includes an experimental version of playback of remote content including proper buffering of the[...]
