SketchyPhysics 3.5.6 (26 January 2015)

malbertsen

Hi I just love SketchyPhysics though I spend much time getting things right. But I love the posibitity to animate whithin SU big time.

How ever I do have a wishing list:

It would be nice if you could save severals animations, and run them simultaniously so that you can animate and control several objects. I.e. animate one item, then run the animations and at the same time animate and record another item in relation to the first animation. And then at the end join the animations into one.
and then have a timeline so you could rund the animations with the timing and speed that you want.
Go back and forth in an animation and see the frame number and time at a given framerate.
Go to a spesific frame number or timestamp in an animation. I have some rather large animations, and use Twilight to render. In Twilight I can start the rendring at a given frame rate (and thus I dont have to render an entire animation) but to find the frame where I will start, I have to run the entire animation in SP and that often takes minutes to find the start frame. Again a timeline would be nice
Off course upgrade to SU2015

And I would be willing to pay for SP if these features were implemented

Ahem...

Should "SketchyPhysics 3.5.6 (January 26, 2014)"
not be "SketchyPhysics 3.5.6 (January 26, 2015)"?

You have a cool free Physics 2D : Algodoo!
Take any image of SU objects (on PNG transparent) and transform them in Algodoo 2D objects!
(not for sensible person)

Minute 3.25 for transparent robot! (Phun is the old previous of Algodoo ! )

Hello Anton. The next SP update you could write "transition" script?
For example:

this.transition(hidden/visible, frame_interval)

or between numbers, from 26 to 35:

@num1 = 26
@num2 = 35
@num1 * transition(@num2, frame_interval)

or

3D point

@original_3Dpoint = [43, 10, 16]
@final_3Dpoint = [22, 10, 5].point_transition_to(@original_3Dpoint, frame_interval)

or Vector

@original_3Dvector = [0, 1, 0]
@final_3Dvector = [1, 0, 0].vector_transition_to(@original_3Dvector, frame_interval)

This is very facilitates our job.

What's the reason for such a behaviour?

@PituPhysics Why not simply include such method in your scripted field? And just fyi, I no longer plan to make any updates to this project. Anyone can take over if they want to.

@Cotty Send me the model, and I'll try figure out what's wrong.

PituPhysics

I'm sorry ... But will be update to SketchUp 16-17-18...234, right?
It does not matter if it is only 32-bit it works, just be good.

Making a FPS game is not finished yet. I started two weeks ago. Look at on youtube or on Warehouse.

That's a nice FPS there, Pitu. I'm looking forward to play it once it's done. The reason I no longer plan to make update to SP because I don't have the C++ source, which without it its impossible to get it working under 64bit applications, and because SP uses old outdated physics engine. Despite that, I started a new project, MSPhysics, which uses the latest Newton Dynamics physics engine. You can see the MSPhysics thread here if you wish: http://sketchucation.com/forums/viewtopic.php?f=323%26amp;t=56852 I'm sure creating FPS games in MSPhysics would be a much easier experience. Other than that, keep up the great work.

Hello! I work on a mac (OS 10.9), and I have problems installing Sketchyphysics. I tried via the Sketchucation plugin from Sketchup 15, and it keeps telling me that it can't load Sketchyphysics on the log :

Does anyone could help me understanding what's happening and how I could fix that ?

Thanks in advance

Anton_S

You get this error because you are running SketchyPhysics on a 64bit SketchUp application. SketchyPhysics only works in 32bit applications. You have to download SU2014 (32bit) and use SketchyPhysics from there.

I work in the film industry as a set designer and I loved this plugin back when I was still using SU2013. It helped me show how a prop might work and to animate a stoyrboard sequence for a set but I haven't been able to use it since:{...

I also do Product Design on the side and you can understand how indispensable this plugin is for that.

Please, Please update for SU2015 64bit and onward. Most of us in these types of industries rely on Sketchup over Maya, ACad, Rhino, Solidworks etc. because of how quickly we can show a client a 'working' model.

Hi there,

I was wondering if Sketchyphysics would be suitable for measuring the overturning moment of an object? I'm working in a museum and we have done some basic 3d scans of objects which I have imported into SU. I have found a plugin for centre of gravity but would like to know if you could apply ground velocity to an object to see what size earthquake would topple it.

Thanks

Hello dna645. I would be more than willing to update SP to SU2015 64bit, but the problem is that I don't have the C++ source, since the libraries have to be compiled under x64 in order to work under 64 bit. I tried contacting Chris Phillips, the author of this plugin, but I haven't got a reply yet. Maybe Chris Phillips want's to publish SP 64bit himself, but he has been pretty inactive since I joined the forums, so I don't know. I'll just wait for his reply.

Hello Lumenous. SketchyPhysics could be used for earthquake purposes, but I'm not sure if the results would be accurate. I mean more data has to be taken into account, like friction between surfaces. However, if friction isn't that vulnerable, here is a demo:sp_earthquake.skp Some adjustments to the slider properties could be made to suit your purpose.

BTW, you don't need a plugin to calc object's center of gravity. Just assign model's shape to Compound2 and the center of gravity will be calculated automatically. To do it, right click desired object(s) and select SketchyPhysics->Shape->Compound2.

Lumenous1

Thanks Anton_S

Very good proof of concept. I'll have a go at testing settings and models and let you know how I get on. Generally our earthquakes are fault slippage in a north/south direction so one piston is fine as I can change the orientation of the object depending on how it would be exhibited. The tricky bit is modeling for any uplift during a p wave event. Maybe a single pulse piston in the up-down direction?

Anton_S

Here is an example of earthquake left/right and up/down movement: sp_earthquake.skp You can adjust oscillation speed/length by adjusting slider properties. Do that by opening SP UI, selecting the desired slider joint, and editing properties.

I want to thank Chris for this amazing plugin.

I do have a couple of wishes for a future release.

Support for 64 bit Sketchup
Support for GPU number crunching monsters like CUDA.

Thank you again and where do I donate to your cause?

Cheers,
Manfred

I'm using Sketchup 2015 and don't seem to be able to install this program. Should it work? If not, what similar physics programs are out there?

mknorr

My understanding is that 64 bit SketchUp isn't supported.
