Free software helps you a lot in many fields, even in generating a GIF animation from images. I wan to show you the use of "convert", a command line tools of ImageMagick, can easily solve this task with two awesome methods: one that simply creates a transition between a series of images and another that makes a morphing among them. Let's see how.
Sometimes you have to change a little aspect, as the text or one or more dimensions, of your object before printing. In these cases you can model from zero your object or try to edit it directly in your software. With OpenSCAD and the parametric design you have to simply edit a text or a variable in a editor and after a render you can save the STL file, ready to the slicer! I will show you two examples that have facilitated my life.
In Xubuntu 18.04 I had some problems with the functioning of f.lux, so I migrated to Redshift. These are software which adjusts the color temperature of your screen in order to prevent eye strain during night-time use and reduce disruption of sleep patterns. In this short article I show you how to install and setup it.
After the installation of the last version of Xubuntu, I discovered that easyMP3Gain doesn't function for this release. However with a little of research I found the correct way to install it and it is very easy!
The program is a graphical interface for MP3Gain, which analyzes and adjusts mp3 files so that they have the same volume. I use it a lot to normalize my music playlist, making some video and it works very well.
The Resynthesizer Plugin Suite contains a practical tool for Gimp that allows you to remove the objects in your pictures after covering them with the adjacent elements. In the post I describe a Linux installation procedure of the version 2, by compiling the source from GitHub or by executing an executable and an example of its use.
From a discussion on Super User, I have discovered an awesome tool that helps you to locate the largest files or directories in your computer, just typing a single command line on a bash terminal. I have only added some code to create a text file without the annoying message "Permission denied". In the article there is also a list of the most famous analyzers for linux.
Recently I have read that a local municipality has finally unblocked an old urban regeneration project in which I worked for many aspects. One of these was the pipe network analysis for that disused area. Fortunately I used PVnet and the job was simple. In this article I introduce this open source software and EPANET2, because its computational engine is used by the first one and it is more complete and powerful. Besides I show you that they can be installed in a Linux system using Wine.
After importing DXF in Blender, some problems start immediately because the common commands present in any CAD don't exist in Blender, or simply aren't so simply to use as in the classical drawing software. Where is the offset? How can I put the quotas? And so on... Fortunately there is PROCAD that helps the users to fix some aspects of own imported sketch. Let's see how install it and translate the UI in English.
I have tried to adapt my old Python application written for S60 smartphones into a modern webapp which should be able to work in any recent internet browser. Therefore I have used jQuery Mobile to convert it and it was very easy, nevertheless my terrible programming skills. Below there is my final app and some description.
If you need a powerful and versatile 3D software not only for modelling and texturing but also for creating interactive applications, you should have to try Blender. Sometimes its interface can appear very different and problematic than typical software, as AutoCAD for example. But with a little of settings and of course patience and time, it's possible to overcome the initial shock and to import own 2D DXF file in this program. Let's see how.
