Round Corners in Houdini

It's been a while since my last post, sorry about that... I was playing with Houdini for the last 1 year, did a couple of jobs with it. It saved my ass a couple of times and I can say that I completely felt in love with it, and I really felt sorry for the years I spent without Houdini. Anyway, after a while later I decided to try to complete the jobs more and more with Houdini and try to go away from Maya a little bit. I'm not going to enter the valley of the differences of the two programs and how awesome Houdini is etc. but I need to say that it feels awesome. Yet, there is another job that I need to finish up (the deadline is tomorrow). The job is about a tire brand etc. Lets cut the chase, the object was not looking good just because they've sent us the production model that they are using to produce the product in the factory, and you now this kind of nurbs models are a little bit too perfect, has sharp edges and a lot of details. In Maya, to break this perfection,

How to Compile PyQt4 for Python 2.6 AMD64 (64 bit) on Windows x64

PyQt 4.5.4 for Python 2.5 amd64 PyQt 4.5.4 for Python 2.6 amd64 Recently I've written an interface for the first time with PyQt4 in Linux for one of our pipeline related scripts. It was working very well under Linux, until I decided to check how it is going to look under Windows x64. Well, it didn't take too long for me to recognize that there is no PyQt4 for Python 2.5 amd64. So I decided to compile my own. By the way you will see that I started for Python 2.5 but compiled for Python 2.6, it is just because, in a panic mode I've installed Maya 2010 to see if the package I found for PyQt4 for Python 2.6 amd64 for Windows x64 will work under. But no it wasn't ( actually it was, but I didn't know that I should add the path that contains the Qt DLLs to environment path ). So I dived in to compiling PyQt4 for Python2.6 amd64 for Windows x64. Here you can find the How-To of that compilation... You need these packages and programs: MS Visual Studio 2008 Python 2.6 amd64

How To install DisplayCAL on Fedora 32 / 33 / 34

Edit: Everything in this post also applies to Fedora 32 / 33 / 34. Both my Photography and VFX workflow heavily depends on ArgyllCMS and DisplayCAL and I recently upgraded to Fedora 32 (and then Fedora 33). Surprise, surprise... Fedora 32 dropped the Python2 support and it is all Python3 now, which is good... But a lot of packages like DisplayCAL which are depending on Python2 are not available any more. I first decided to try porting DisplayCAL to Python 3. But it is huge task and DisplayCAL has some ancient code styling and dependencies to some unavailable packages. So I quickly resigned from that. It is much much easier to try to install the RPM packages and their dependencies from Fedora 31. Hopefully, it is an easy task. Here are the instructions to install DisplayCAL on Fedora 32. Download the following RPM packages that are compiled for Fedore 31 (which will work for 32/33/34 too): python2-wxpython python2-gobject-base python2-gobject DisplayCAL You can use the followi
