This project includes some VS Code settings that makes it easy to render any sub component of the full model: Therefore: Customized workflow settings included Terrforming should be an explicit action. You want to be able to load the file to modify the running program, without worrying about mutating the world around you.

However, it is an anti-pattern, imo, to have side effects and potentially compute heavy things, to happen on file load, if it can be avoided. why? Isn't it super convenient to just load the file and rerender the model? Yes, it is. Rich Comment) form, which makes it not run when the file loads.īut.

It hides the (render (model)) evaluation in a (comment.You will see the updated model rendered in OpenSCAD immediately. Now you are set! All the examples, except example.clj will re-create the render.scad file when you load it in the REPL (like in step 6 above). This will render the model and OpenSCAD will hot reload it every time it updates.This creates the render.scad file at the root of the project.Load the file, Calva: Load Current File and Dependencies.Start the project, Calva: Start a Project REPL and Connect (aka Jack-in).Start VS Code and size the window so that it is above the left pane of OpenSCAD.With those things installed on your computer, you'll be interactively rendering 3D models from Clojure code in something like one minute:

(And you don't need to install it.) OpenSCAD shows you the results immediately, in an incredibly easy to use viewer. It makes it super easy to compose in 3D space. scad-clj is a wrapper/transpiler from Clojure to.

The software stack is Java, the clojure tool, scad-clj and OpenSCAD. Please consider to subscribe to the CalvaTV channel! (Sorry about the somewhat extra amateur-ish production, my recording software was acting up on me, big time.) Install There is a demo of the project on YouTube. To use the new palette with our mpeg video type: ffmpeg -i input.mp4 -i palette.png -r 12 -s 320x180 -filter_complex ' paletteuse' prettyOutput.OpenSCAD + scad-clj + Calva => Smooth and enjoyable Interactive 3D Modelling. This is our newly created 256 color palette for our specific video which is generated by the palettegen filter. When we look in the folder of our mpeg file well noice that a file ‘palette.png’ has been added. To create this palette type: ffmpeg -i input.mp4 -filter_complex ' palettegen' palette.png Luckily FFmpeg allows us to create a custom palette for our specific video. This is in general not optimal for the specific video that you want to convert. FFmpeg by default uses a generic palette of 256 colors that covers the widest range of content. Because GIFs only uses 256 colors the number of colors from the mpeg4 needs to be reduced. This is due to the default GIF encoding in FFmpeg. When we look closely at the resulting GIF we clearly notice some shortcomings in the animation. For the size of the GIF make sure that the aspect ratio remains the same or the resulting GIF will be distorted. This command reduces the framerate to 12 per second and resizes to 320×180 pixels. To achieve this we need the following command: ffmpeg -i input.mp4 -r 12 -s 320x180 output.gif In order to reduce the size of the file we can reduce the size of the images or we can reduce the number of frames per second. So you’ll end up with a file that’s much bigger than the original mpeg4 and probably something that exceeds the upload limit of Diaspora*, Friendica or Mastodon. Unfortunately gif images are large due to their lossless data compression. Where the name of the input file is input.mp4 and output.gif is the name of the output file. The basic command to create an animated GIF from a mpeg4 is: ffmpeg -i input.mp4 output.gif

Below I will explain not only how to create a animated GIF from an mpeg4 movie but I also provide instructions to improve the quality. In fact suppose this post is more for users that like to tinker a lot with their animated GIFs. A word of warning FFmpeg is a command line tool that’s very versatile but it’s not for everybody. FFmpeg is available for Windows, Linux and OSX. FFmpeg is a good FLOSS tool to create these animated GIFs. Animated GIFs are after all these years still pretty popular.
