SketchyPhysics 3.5.6 (26 January 2015)

chri

Hello,

Just downloaded SU 2016 64 bit. I was looking for a physics simulator, it seems this is the only one so far. But it doesn't install on SU2016 64 bit? Will there be a new version soon? I need it now.

Thanks.

hi sekramer10

Perhaps , you can use MSPhysics by Anton

I received the C++ source of SketchyPhysics and been looking over it for a while now. I tried compiling it under 64bit but did not succeed. SketchyPhysics source is shipped with the 32bit version of the Newton 1.53 static library however not with the 64bit version. In order to compile SketchyPhysics under 64bit, I would need to have a 64bit version of the Newton 1.53 static library, which would require recompiling the source of Newton 1.53 under 64 bit configuration. The problem is that SketchyPhysics source does't comes with the source of Newton 1.53, as well as, the source of Newton 1.53 is no longer available on the internet. This meanders my ability to compile SketchyPhysics under 64 bit. I could upgrade SktechyPhysics to use newer versions of newton, but they could change the way older SketchyPhysics models work. Not to mention the problems that could come upgrading SDL libraries and all the adjustments that would have to be made in order to compile SketchyPhysics under Mac OS X. However it's worth a try. I'll keep it posted.

I have the source to 1.53 as well as the 64bit library. It ships as a static lib, I've got an automator script that runs lipo on the library to strip out the extra stuff and then "ar" to dump the object files and then a g++ link command to put it all together as a dylib so that the ruby c bridge can open it.

Let me know how to get it to you and we can keep moving.

Hello Kevin,

I haven't been working on SketchyPhysics in a while, but I would appreciate the 64bit version of the newton static library and more importantly the source to newton 1.53. It is good that you have the Mac side going as I have relatively no experience compiling and running libraries on Mac OS X. You could send the files to anton.synytsia@gmail.com via google drive or any other desired storage and I would inspect it from there.

Do you see a way so to port SketchyPhysics for SUp 64-bit, or should we "players" focus on MSPhysics?

Anton_S

Yes, there is a way to make SP compatible with SketchUp 64bit. I might work on it when I have time.

faust07

No stress please. Time will tell. SketchyPhysics 32-bit is on a high level and works very well thanks to your improvements and bug fixes. MSPhysics has reached similar an higher levels and is a powerful simulation tool. Thanks again!

Can anyone help me out? i have multiple versions of su, but in each one the same error message pops up the second i open skutchup. I cant get to any of the tools, its like its not installed, but i have uninstalled and reinstalled it multipule times and nothing seems to work. Any help would be appreciated, thanks.

Hi firedrake this might help u along all your multiple versions of su need to be 32bit only

and in profile i noticed your a mac user try d/l SketchyPhysics 3.7.3 version a lot bugs have been fixed

How to install:
Mac: /Library/Application Support/Google Sketchup #/Sketchup/plugins

(On a Mac, make sure that the contents of the SketchyPhysics folder you got out of the downloaded zip are in the Plugins folder itself, NOT in a SketchyPhysics folder within the Plugins folder.)

hope it helps

Hi Anton - any chance of an update? Happy to start a Go Fund Me page to pay for your efforts in creating this magnificent plugin.

Unfortunately, the plugin doesn't seem to be compatible for SketchUp 2026. Every time I load it, I get these errors:

@Joeyinsully Sketch Physics hasn't been updated in over ten years. It hasn't worked in newer versions of SketchUp for years so it's not surprising that it doesn't work in SketchUp 2026.

Is that open source? Maybe in that case it can be updated to fit the new ruby/API rules?

We have chatted with Anton about it and it is a huge undertaking.

He is focussing on his career currently. I'll try raising the topic again.

Of course I was thinking about "cheat-coding"
