If you shoot with an Samsung Galaxy M33 in the "Portrait" mode Samsung saves three images inside one jpeg. The first one is the one you see if you open the photo with any application. The second one is the image without any filter applied and the third one is the shot from the depth map camera. Main Image You can get the images from all cameras with the command line tool " exiftool ". First you can check with this commands, if the image contains any additional images:   "exiftool(-k).exe" 20220921_091253.jpg "-embedded*" -a Embedded Image Name : DualShot_1 Embedded Image      : (Binary data 2449408 bytes, use -b option to extract) Embedded Image Name : DualShot_2 Embedded Image 2    : (Binary data 576210 bytes, use -b option to extract) -- press ENTER -- And with this command you can check for a depth map : "exiftool(-k).exe" 20220921_091253.jpg -"*depth*" Depth Map Name      : DualShot_DepthMap_1 Depth Map Data...

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/ ...

Moon with displacement map I played again a little bit with A-FRAME to create the moon. Thanks go to CG BOOST for giving me the link to the NASA image and displacement map from the moon and to the Museum of Science in Boston hat created the nice 360° star background . https://github.com/supertobi/aframe-moon-with-displacement-map Earth with moon But the Moon was not enough. I created a earth and now the moon is rotating around the earth: If you have a VR headset please use it! The earth and cloud textures are again from the NASA and then improved with GIMP.   https://github.com/supertobi/aframe-earth-with-moon Matterhorn Then even closer to the ground I made a 3D piece from the Alps with the Matterhorn. I was inspirited by @Taky_ed Matterhorn, I used GIMP for editing the textures, A-FRAME for displaying and the stars background from Museum of Science in Boston .   https://github.com/supertobi/A-FrameMatterhorn

You can easily pimp your IKEA LAMPAN by adding a paper cutting inside: The Math First we have to do some math. The lampshade is a geometric shape, a truncated cone. The pattern is part of a circular ring, i.e. a circular sector from which a second sector is cut out: The theorem of Pythagoras gives m = √ h²+(R-r)² and from the theorem of rays we get the equation R/r = M/(M-m). Thus: M = m-R/(R-r) applies. The sketch also shows: 2R-π = 2M-π-(α/α) and from this follows α = 2π-R/M - that is 360-R/M degrees. With this information you can create something like this in Inkscape: Bending a rectangular You can now start editing. But I like it more to work on an rectangular shape. Therefore I'll add some helping lines. I insert an additional node on the left and on the right: Then I create a centre line as helper for the next steps and use the extension "Draw Handles": I changed the colour to grey to make the handles more visible: Now I can start t...
