First of all what is Aerialod and why do i need an alternative. Aerialod is an tool to create fast 3D voxel images out of height maps. Advantages and Disadvantages of Aerialod Advantages: User-Friendly: Aerialod is an easy-to-use tool for creating 3D terrain models. It caters to both beginners and experienced users who want to achieve results quickly. Freeware but not Open Source: Aerialod is free to download but does not allows users to modify and extend the source code. Variety of Features: Aerialod supports the generation of various terrains, the use of real satellite data, and the creation of synthetic heightmaps. This makes it a versatile tool for different applications in geodata visualization. Disadvantages: Lack of Advanced Features: While Aerialod offers many useful functions, it may lack some advanced features found in professional 3D rendering tools, making it less suitable for certain applications. Not Open Source No new version since 2023. Overall, Aerialod presents an in...

Alexandre Prokoudine does a great job with his Libre Arts blog and he made a big overview of the year 2022 with a preview of 2023 : As he looks at the big picture I collected some news from small more hidden open source graphics projects: Mobile As I'm only interested in the non mainstream mobile stacks I'm ignoring Android an OS here completely. Megapixels Megapixels got two new releases (1.5 and 1.6) with nice improvements.Meanwhile is Purism working on an fork called millipixels that is using libcamera. libcamera The first version of libcamera released and a lot of big companies like RedHat, Purism and the Raspberry Pi Foundation are working together to improve the camera stack. Image Viewer Image viewers are the kind of programmes that every one thinks are easy to write. But then you realise not only there are thousands of different file formats with metadata (with informations like "rotate this image", "this is an panorama", "geo locations...

Alexandre Prokoudine does a great job with  his Libre Arts blog and he made a big overview of the year 2021 : As he looks at the big picture I collected some news from small more hidden open source graphics projects: Mobile PinePhone and Purism Librem 5 got camera support and a portable new camera app (GTK3) Pine64 and Purism worked on phones with a default Linux Kernel. And they both now have camera drivers and they worked together on the camera app Megapixels:   https:// blog.brixit.nl/pinephone-came ra-pt4/ https://puri.sm/posts/librem-5-news-summary-april-2021/     pine64.org now sells a Open Source IP Cam https:// pine64.org/cube/   ResberyPi   ResberyPi released a new version of there distribution and switched the camera stack to libcamera . Panorama Tools As Alexandre already talked about Hugin and SkyFill I have only two additions: Lux   A new free OpenGL image viewer specialists for panoramas : https://bitbucket.org/kfj/pv/src/master/ ...

Download the GLOBE elevation tiles from here:  https://www.ngdc.noaa.gov/mgg/topo/gltiles.html Unzip the file Rename the file to *.data Start GIMP and open the file. This dialogue will appear:  Now use the Colors->Levels Tool to make the data more useable:

I've created a isometric like image of the Isle of Mull in Scotland with GIMP, G'mic and Inkscape for a photo book: I used Gimp 2.9.9 with the new HGT file import and the height maps from the NASA. You can read more about it here: https://dablogter.blogspot.de/2018/01/gimp-now-supports-hgt-file-format.html G'mics 3D elevation plugin: Water texture from here: https://www.roblox.com/library/31952856/Water-Texture-FREE The land colours are from a blurred screenshot from Google Earth. Inkscape for the markers: The sun is the standard "Sparks" brush from GIMP. Cloud and bird brushes from https://www.deviantart.com https://para-vine.deviantart.com/art/Cloud-Brushes-152820554 https://wingsofahero.deviantart.com/art/Bird-Brushes-119021426 https://wingsofahero.deviantart.com/art/Flying-Bird-Brushes-116541763 And a lot of fine tuning in GIMP, here is a screenshot of the layers dialogue:  

Here come the promised update. I've added text and the flight routs to the image: This time I'd like to thank the authors of this two YouTube videos to help me with Blender.    1. Text in Blender    2. Curves in Blender

Hello my latest little project is a 3D low polygon map. I used Blender and Gimp to create this map: I've started with an elevation map of Europe I found on the website from "The European Environment Agency" (EEA). Thank you EU for this image: http://www.eea.europa.eu/data-and-maps/figures/elevation-map-of-europe Then I had to cut of the black border with Gimp and created a second image as height map: For this step I converted the image to black and white and then used the curve tool to make the mountains darker. This will make the mountains in the final image higher and easier to discover. Then I used this tutorial to create the 3D image in Blender: http://johnflower.org/tutorial/make-mountains-blender-height-maps But I didn't  subdivide in as many parts than the tutorial ans I haven't smoothed, because I wanted a low polygon look of my image and not a realistic one. After this step I gave the plane the original colour image as textur...

It's again this time of the year, that I write a blog post. This time I’ve had to create an embroidery file. The initial design was made with Inkscape. Then I looked at different programs to create the embroidery file. As I use mainly Linux I first looked at this programs: Embroidermodder 2 Embroidermodder 2 is an open source program. It is far away from ready, but still active developed. The SVG import crashed even with the simples SVGs. What works is to use this tool as a viewer and converter for different file formats. Creating new files was not so successful. https://www.libembroidery.org/ GitHub repro: https://github.com/Embroidermodder/Embroidermodder ) Inkscape - Extension 1 There is an embroidery output extension for Inkscape. I tested it but was not very satisfied. Inkscape is not optimized for this job. You simply don’t have enough control. http://www.jonh.net/~jonh/inkscape-embroidery/ (No longer active devolved, the autor refers to: https://inkstitch.org/ ) ...

(You can find a English version of the text below.) Ich habe mich beim Libre Graphics Meeting 2014 mit Timelapse Tiltshift Video beschäftigt. Das Ergebnis könnt ihr hier sehen: Für das Video habe ich erst mit meiner Kamera alle 5 Sekunden ein Foto machen lassen. Danach bin ich weitesgehend nach diesem Tutorial vogegangen, um daraus ein Video zu machen: http://ubuntuforums.org/showthread.php?t=2022316 Allerdings habe ich nach dem Ändern der Größe der Bilder mit darktable bearbeitet um den tiltshift effect zu bekommen. Hier vielen Dank an houz für dieses Tutorial: https://houz.org/posts/2014/03/13/fake-miniatures-in-darktable/ Nachträglich habe ich noch Musik, und den Titel am Anfang und den Abspan mit Kdenlive hinzugefügt. Die Musik habe ich übrigens von opengoldbergvariations.org . English version: On the  Libre Graphics Meeting 2014 I've discovered how to create a timelapse tiltshift video.
