![]() ![]() The next thing is to start using the geometrical shapes as building blocks to make things. Or, better still, from the layers dialog, make the background invisible and choose Image -> Merge Visible Layers so you will have the background on a separate layer and you can work further on it if you like. You can choose Image -> Flatten Image to merge the layers togerher so you can save as jpeg or any other format than xcf. Now you have a cool image of a Light-Source-Shaded Cube. Now apply for your ‘Cube GIMP Licence’ from the nearest GIMP Station ) 4. Once you find the shading look good, you can flatten the image and our little tutorial-cube is finished. This time you pull the gradient from left to right, according the arrow in the picture. So I suggest you lighten the dark blue color a fair amount, it’s easier to get a light gradient that way. Now you probably know we want to make yet another path and this time the gradient has to be even lighter than in the first side. Again, create a new transparent layer and name it (who quessed? :) Top_side. Our final ultimate task is to create the top, side #3. You don’t want to leave any holes so the background can be seen through… It’s better to overlap the lower layer a bit than leave a space between them. This way we get a darker gradient suitable for the shadow-side. Take the Gradient Tool again and, still with the same colors, make a gradient from farther up-left to near the selection’s lower-right corner (see image on right). Use the Path Tool and try to make the right side of the cube and turn it into a selection. Create a new transparent layer and name it Right_side. We also want the lighter end of the gradient to be near our imaginative light source. This way you get a quite light-colored face for the cube, and it is just what we want here. Select the gradient-fill tool and, starting from the top-left of the selection, ‘drag’ the gradient quite far down-right (see the arrow in the image. Next we must choose some nice colors for our gradient, choose white for the foreground color and some dark-blue for the background (we are making a blue box, remember?) Something like that on the image nearby. Once you are satisfied with your “box”, convert it to a selection using the button “Create Selection from Path” (in the Path Options dialog) or using “Selection to Path” (in the Paths tab). Your path should look something like the one on the right. You can adjust the points’ places if you can’t get them right at the first try, see the Path tutorial for more information on that. (If this causes you trouble, don’t worry. Imagine the blue cube on the right side into your canvas, we’ll be doing side #1 now.Ĭhoose the Path tool and make something like the side #1 on the blue cube, think about the perspective. If it is not selected, click the layer’s name in the dialog. Make sure you have the new layer active by checking the layers-dialog. ![]() Now create a new transparent layer, and name it Left_side so you know what layer I’ll talk about later on. You can also get these tabs using Dialogs -> Layers and Dialogs -> Paths. This dock is present in the default GIMP installation. During this tutorial, you will have to use the Layers tab and optionally the Paths tab from the dock “Layers, Channels, Paths, Undo”. Make the size 256x256 pixels and choose RGB for the type. Let’s get started! ¶įirst we must create a new image for our creation. ![]() If you are new to GIMP I suggest you to go to the GIMP homepage in and first read through the Documentation section there. Paths are covered in my other tutorial, and I recommend you to read it before going further if you find the material here confusing. I was thinking about this, and I did not want to make this an ‘entry level’ thing, basically to avoid bloating this too big and duplicating other people’s work. You should be familiar with GIMP’s dialogs and menus. Notice! This is not a ‘back to basics’ -tutorial. I hope you get some help and new stuff to put in your GIMP Tricks Sack :) I personally use this technique for nearly all my work. I will concentrate on the Path tool since I find it so useful for this purpose. This tutorial is about making simple geometrical shapes with GIMP. Polygonal shapes are especially useful when painting some geometric objects, as you can draw one side at a time (into different layers if you want). But you can also use paths to create different polygonal shapes if you don’t ‘pull out the handles’. Maybe the best thing in it is the smooth, beautiful curves it produces. The Path Tool (replacing the old Bezier Selection tool) can be used in many creative ways.
