OpenSCAD is a software for creating solid 3D CAD models. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.
      OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file. This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designs that are defined by configurable parameters.
      OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data exchange format for this 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.

CloudCompare is a 3D point cloud (and triangular mesh) processing software. It has been originally designed to perform comparison between two dense 3D points clouds (such as the ones acquired with a laser scanner) or between a point cloud and a triangular mesh. It relies on a specific octree structure dedicated to this task.  Afterwards, it has been extended to a more generic point cloud processing software, including many advanced algorithms (registration, resampling, color/normal/scalar fields handling, statistics computation, sensor management, interactive or automatic segmentation, display enhancement, etc.).

            Saber is the notes app built for handwriting.
        
      
            It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly.
        
      
            Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class.
            Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss.
        
      
            Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own!
        
      
            The app is completely open-source so that anyone can view the source code and see exactly what it's doing and how it handles your data. Many other note-taking apps are closed-source and proprietary, meaning that their inner workings are a mystery to the public.
        
      
            As someone who studies maths, highlighting multi-line equations was always a hassle with other apps, where the highlighter would change color when it overlapped with itself. Another problem I had was that in some apps, the highlighter would render on top of the text, fading it out and making it hard to read.
            Saber's highlighter has no such issues. It utilizes canvas compositing to render the highlighter in a way that is consistent with/better than traditional paper, where it handles overlaps and maintains color consistency.
        
      
            Saber has everything you need to keep your notes organized. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. And even though a note may be buried deep within a nested folder, you can still access it easily with your most recent notes always available on the home screen.
        
      
            Discover a whole new way to capture and organize your thoughts
            with Saber. Whether you're a student, professional, or creative
            mind, Saber is your trusted companion for digital handwriting.

jExifToolGUI is a java/Swing Windows/Linux/MacOS graphical frontend for the excellent command-line application called ExifTool by Phil Harvey.ExifTool is a platform-independent Perl command-line application and library for reading, writing and editing meta information in a wide variety of files. Exiftool is by far the best and most extensive metadata tool available! It reads and writes metadata information from/to many files, but primarily focuses on photos/images. It reads/writes exif, gps, xmp, maker notes for many cameras, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix and many, many more tags. It can use a "reference" image to write the tags to a multiple set of photos or a complete directory containing photos. Author/creator/maintainer of ExifTool: Phil Harvey.jExifToolGui is a java/Swing program that functions as a graphical frontend (GUI) for exiftool. Many thanks go to Phil Harvey for his excellent tool. Without ExifTool, this jExifToolGui Graphical frontend for ExifTool would never have existed.jExifToolGui is (just) a graphical frontend for ExifTool. It can use a "reference" image to write the tags to a multiple set of photos, like gps tags for photos that were taken at the same location but somehow miss or contain the incorrect gps info. jExifToolGUI also contains extensive renaming functionality based on the exif info in your photos.

PhotoCollage allows you to create photo collage posters. It assembles the input photographs it is given to generate a big poster. Photos are automatically arranged to fill the whole poster, then you can change the final layout, dimensions, border or swap photos in the generated grid. Eventually the final poster image can be saved in any size.The algorithm generates random layouts that place photos while taking advantage of all free space. It tries to fill all space while keeping each photo as large as possible.PhotoCollage does more or less the same as many commercial websites do, but for free and with open-source code.
