Carve Library for new Boolean Operation soon in Trunk


All product designers and architects will love this one. The new Carve library finally is making its way into trunk and bringing to us much faster boolean operations. Now interactive cut section animation and non-destructive modeling are doable in Blender. The code is very stable, does not crash as much as the current boolean code and is very fast.

The material system is now also supporting a boolean material. To do this the boolean material (pink) has to be added as a second material to the monkey. As you can see this works during render time as well as shaded view.

To learn more about it, I uploaded a test file here:

There are plenty of builds for OS X and Windows now available at

      It’s somewhat easier to do your own builds on Linux than on other platforms. On Debian derivatives (e.g. Ubuntu, Mint), a simple “apt-get build-dep blender” ensures that you have all the necessary dependencies to do the build.

  1. The new booleans are great.  The only problem is that the calculations are a bit slow.  I only wish that there had been a function included so that when one tries to move, rotate or scale one of the objects involved in the modifier that the calculation update be temporarily suspended until the change has been effected.

    I agree on that one with you - I am not sure if they kept it this way because you need this refresh for frame by frame animation.

    Still this is much better than the old solution.

  3. This, is seriously cool.  Only possible question I have might be, "how work Control R?", (Or perhaps, "In the process of intersecting a boolean with the object a boolean appear, no understand!!!!")  ((All kidding aside though, this looks awesome.))


    It's possible to implement, this carve boolean into the one brick of the game engine... !?? To cut and re-cut monster, doors, cars, space ships, fingers, hands, heads and more a lot of another things... !???


  5. I'm not getting how the boolean material is applied. Are there any resources or instructions on how to work this spiffy tool? (I'm going to find this VERY handy for the mechanical assembly animations I've been doing! Customers love to be able to see inside to see how the inner workings look...)

    •  I was missing this too, but it says above in the article: "To do this the boolean material (pink) has to be added as a second material to the monkey"

  6. INCRE... wait for it... DIBLE!!!
    Amazing, I've been waiting for this! I wanted to boolean an pattern on a ring for 3D Printing, but Blender would always crash. NOW IT WORKS :D:D
