You will be taken to a new page, where you can change the sequence of the frames and the animation speed. Once the files are selected, click the ‘Upload and make a GIF!’ button.

If you want to make this process a bit easier, you can zip the PNG files first and then upload them as a single ZIP archive.

My favorite service is, because it’s simple, free and doesn’t need any software installed – everything runs in a web browser.

#OPENSCAD TUTORIALS HOW TO#

There are various ways how to create an animated gif or a video from a bunch of images. scad file is saved, a bunch of new image files will be created – frame00000.png to frame00359.png.

Wait until one full rotation finishes, then the Dump Pictures will automatically un-tick itself. The rotation will slow down because OpenSCAD will start saving individual images on the hard drive. Just tick the Dump Pictures option next to the text fields. However, if you don’t have such a program, you can export individual frames of animation. If you have the necessary software (like Gifcam), you can actually just record the desktop (or a part of it) and be done relatively quickly. However, our goal is to show the 3D rotation to someone, who doesn’t have OpenSCAD – and the best way would be an animated gif or a video. If you followed the tutorial precisely, you should now see t he rotation in the OpenSCAD window. One complete rotation will take 12 seconds (360/30). This will result in the model rotation in one-degree steps at the speed of 30 frames per second. Then enter ’30’ into the FPS field and ‘360’ into the Steps field. Modify the $vpr vector, so the last element (the value of rotation in the Z-axis) steadily increases from 0 to 360 after being multiplied by the $t coefficient: $vpt = The Steps field determines the number of animation steps.Īnimations in OpenSCAD are based on a mechanism that refreshes the viewport every second – the count of refreshes is set in the FPS field, and the value of the special $t variable increases from 0 to 1 in steps determined by ‘1 divided by the number in the Steps field’. The FPS field determines the Frames Per Second, which defines the speed of the animation in the preview. Time does not concern us – it just shows time during the animation. A new panel will appear above the tool panel in the lower section of the window – there are text fields named Time, FPS and Steps. In the OpenSCAD menu, choose View > Animate. It’s the degree of the Z-axis rotation and it can be set in the 0-360 range.

Now try to change the last value of the $vpr vector – its value is 30 in the sample code above. You can move the camera/view as much as you want, but once you press F5, it will return to the configured (coded) position. Once you render the viewport, the virtual camera will be positioned into the coded position. These values can be modified in the OpenSCAD model code as a special $vpr (viewport rotation), $vpt (viewport translate) and $vpd (viewport distance) variables.Īdd these three variables into your code and modify the values so the viewport looks good on your screen (it will depend on the window size or LCD screen resolution). These three parameters will change depending on the camera movement, zooming or rotation. In our case, it says: Viewport: translate =, rotate =, distance = 172.84 Now take a look at the status bar at the bottom of the OpenSCAD window. We will modify the code to place the model in the center of the coordinate system: offset = It’s not mandatory, because it’s possible to change the origin point for the rotation, but this way it’s much easier. If we want to create an animation that rotates the object around the Z-axis, it’s a good practice to place the model in the center of the Z-axis. A complete model is created after calling the house() module and this is how it looks: For the purpose of this tutorial, I have used a simple model of a house that you can download from my GitHub. The following steps can be used for any model.

Using a web service called, we’ll turn the frames into an animated gif or a videoĬreating and preparing the model for animation.

Then we’ll use OpenSCAD to export individual frames of animation.

We will use the application’s features to make the object rotate automatically.

Start with creating a model in OpenSCAD.

So instead of sending a couple of screenshots, we can actually prepare a short animation of the model being rotated around selected axes – and actually even more. This is especially useful when you want to show the model to someone who doesn’t have this application and can’t check out the model in full 3D. That’s why we’ll take a look at how to take a model programmed in OpenSCAD and animate it. And when it comes to moving picture, they often say more than a whole book. According to a proverb, a picture says more than a thousand words.
