Episode 041 – 3D Text Using Interpolation

by heathenx

In this screencast I will demonstrate how to make three-dimensional text with the interpolate effect in Inkscape v0.45.

    working with that many paths makes my computer slow down ridiculously. that’s why after interpolation i select all copies but the top one, i do a union on them and give them fill colour same as the stroke. this way i get 2 paths instead of 50 what my poor computer really likes 🙂

  2. Javier Samudio Says:

    Another way of doing it, insted of using interpolation, would be thru Effects/Generate from path/Extrude.

    I would be happy if you can mail me each of your tutorails.
    They are quite helpful for learner .

    godlike! its awesome with what easy movements you’re creating a 3d-text. (sorry 4 my english)

  7. scyg Says:

    You really shouldn’t need more than eight or so copies of your original text for this kind of effect – 50 is definitely overkill.

  8. heathenx Says:

    50 might be overkill but 8 is definitely not enough for my tastes. I suppose it depends on the size of your object and how closely one zooms in. The point is to not notice that interpolation was used as opposed to extruding.

    I agree with some on here… it starts to hog resources big time

    Nice tutorial but when I save it as a PDF it loses the Blurred layer and it looks ugly, How can I fix this.

  11. heathenx Says:


    If you have any blurred objects then you’ll have to rasterize them before exporting to PDF. You can do that with the Make Bitmap Copy feature. However, you only have to do that in 0.46. In 0.47pre4 they have added functionality to the PDF exporter that rasterizes those effects automatically for you if you choose to do so. I stopped using 0.46 when 0.47pre4 was released. It has some bugs but it’s pretty stable now. I recommend you try it. You’ll find binaries for all three major OS’s.

    thanks dude it works. U rock

    […] Ich kenne mich zwar mit dem Illustrator nicht aus, aber die Schriftzüge und Co., die inkscape möglich macht, die sind schon lecker. Wen´s interessiert, schaut sich am besten mal ein paar dieser Videos an: –klick– […]

    Im using inkscape 0.47. I wasnt able to figure out how you selected both items at the same time right after you duplicated the first one and slid it down.

  15. heathenx Says:

    Can you give the the time so I can get to that specific point in the video?

  16. Lynn Livingston Says:

    This is a great tutorial. However, I cannot make it work in ver .47. There is a difference when I convert to path and break the path apart. In .47 I did not have to cut the font inner features back in using the “difference” function. Also, after duplicating and offsetting the original, I’m not able to interpolate the space between them. I can select both objects, but when I perform the “interpolate” task, with options choosen as in the video, nothing happens although it appears to be doing something (I get a DOS window popup). If I try the same scenario, but choose “extrude” instead of “interpolate”, I get an error that says 2 paths must be choosen. I think I am choosing 2 paths (choose one path (object), hold “shift” and choose another). Anybody have any ideas?
    Thanks for the tutorials, they really help folks like me who don’t get the seat time I really need!

    Could it be that you do not have two objects that are paths? It is needed in order to interpolate between objects. To convert text to a path in 0.47 try these steps: Select text, Shift+Ctrl+C to convert to path, Shift+Ctrl+G to ungroup, and Ctrl+K to combine. Now when you double-click on the text it should be one complete path. When that is done, window around both text objects and try interpolating.

    Same holds true for extruding. Two paths are needed before the effect can be achieved. 🙂

  18. Vince Says:

    Hopefully this is still being maintained and feedback is being provided. It’s dated I know.

    I’m having the same problems that Lynn was having above. I’ve tried the suggestions provided, even tried extruding, but nothing seems to help. Of note, after attempting to extrude I get a message back that sames “Need 2 paths selected.” I make sure both levels are pathed and try again, I get the same message.

    When I try to interpolate, it does one of two things, either nothing, or all 50 levels of the text I’m trying to interpolate appear. When I try to proceed after interpolating, and drop the colors into the text, the stroke color is an outline of the text, it doesn’t fill in the lower level like it does in the video.

    This is somewhat frustrating, but I really want to learn how to do this.



  19. heathenx Says:


    Pay close attention to your status bar in Inkscape. Make your text and convert to path. Notice that your text is now a group which is probably what is tripping you up. Make your text a single entity with the combine command then try interpolate. 😉

  20. Michel Says:

    Hi, I had similar problems. To interpolate try:

    Into the interpolate box:

    flag –> interpolate style
    interpolation method –> 2

  21. Nikos Says:

    Great tutorial.
    Not only shows how to create 3D Text Using Interpolation but also the basic technique to create shadows and highlights.
    Thanx alot 🙂

  22. scyg Says:

    If you want to use a lot of interpolation steps, you can save yourself some screen rendering time by ungrouping (ctrl-shift-G) the interpolated paths and then unioning them (ctrl-+). Then you use the result as the “extrusion”, with one of your original paths as the “face” of the text. That way you get the smoothness of the multi-step extrusion without the weight of 50 or so paths. Here’s an .svg to illustrate (right-click to save file): http://cygielski.com/testing/extrusion_sample.svg.
