Pleasant3D v1.1 released


I’m happy to announce the release of Pleasant3D v1.1.

There are some awesome new features in the new version:

  • Pleasant3D now includes QuickLook plugins for STL and GCode files!
  • The preview views are now zoomable.
  • Objects can now be rotated by arbitrary angles.
  • … and many more.

Check out Pleasant3D’s brand new home page for a full feature list.

I recorded a short movie, showing off the new features of Pleasant3D v1.1:

Thanks’s to all of you, sending me feedback!

Pleasant3D v1.1 is available for free download here:


  1. The improvements you have made to Pleasant3D rock. More people need to know how awesome this software truly is. Expect a donation from me soon.


  2. @Eric: Thanks. Pleasant3D uses a good deal of GCD code. Also, Pleasant3D is a spinoff from another (larger, not yet released) project which uses OpenCL. Both projects have and will have the same code base.

  3. Thanks for the info. Does Pleasant3D need OpenCL? I don’t think the hardware in my older MacBook supports it.

    Anyhow, now I’ve got a more compelling reason to by the Snow Leopard update than I had before. :-)

    • Eric,
      Pleasant3D v1.1 (the binary available for download) currently doesn’t contain any OpenCL code. This will likely change in the future (OpenCL could speed up gcode parsing a lot). As said before, Pleasant3D is a spinoff from another project (which does contain OpenCL). The plan is to merge more and more functionality to Pleasant3D with each update.

  4. No, at least not by me. Most of the code (i.e. anything what’s not an OpenGL call) is pure Objective-C/Cocoa. Also, the code makes heavy use of GCD (Grand Central Dispatch), which is (to my knowledge) only available on Mac OS X 10.6 (and later).
    So a Windows version would be a complete rewrite, not a port.

  5. Apple released GCD as open source, but I don’t know whether it has been ported to Windows. Cocotron provides Cocoa-compatible libraries for Windows.

    I’d be more interested in a Linux version, but that looks harder, at least until Cocotron has a Linux version.
