MSPhysics 1.0.3 (16 October 2017)
-
Thanks, Anton for the explanations.
The Indigo renderer update/halt time difference seems not to be a MSP or hardware problem. I've tested it with different model sizes on different machines. I'll try to ask this in the Indigo forum. In the SkIndigo Render Settings one can set the halt time a few seconds longer than the before tested update time and all is fine.The incomplete results of the view.write_image function in SketchUp 2017 I will report in the SketchUp Community Forum.
I hope my problems with Servos I can demonstrate in the following examples more dramatically. A mode to hold connected objects in the pivot position would be fine.
The tests with the Update Rate I did only to improve that. No need to change the oscillator script. For non real time simulations (large models with much MSP-objects) the oscillators based on frames are better than based on world time. (on the end the film with 30 frames per second brings the "real time" feeling).

Another problem with a servo and a non-collision object. After the fall of the candle a strange behavior of the flame arises. Collision, gravitation, etc. do not seem to be completely canceled. The joint oscillates in high frequency, which can even lead to a crash. What can I do?

Hi Anton,
Thank you for your reply. Since I am French I do not speak English well.I did not understand everything ... the hand is unstable ?

funny ?
I do not find
She works well my hand . I like sketchup + msphysic because I understand what I do. Other software is too complicated for me. You will have time for: "The table with angles and times must be converted to a Ruby Hash".At the moment I try this function of time:
ft = 9,75 -7,91cos(6,28world.time) -0,88cos(18,84world.time)
-0,32cos(31,4world.time) -0,16cos(43,96world.time) -5,27sin(3,14world.time)
Here is the Fourier series that works
youpi !
-9.75+7.91Math.cos(6.28world.time)+0.88Math.cos(18.84world.time)+0.32Math.cos(31.4world.time)+0.16Math.cos(43.96world.time)+5.27Math.sin(3.14world.time)
it does not work. What to do? thank you
Thank you very much, Best regards.

Poorly connected the groups together. I added "Ball and Socket" joint in a new group, and a new "Up vector" to green axis. This disables the rotation.
Try it now: Test_03.skp

Hello, luckyvac,
I added a small script to your guitar to play the sound and control arm/wrist movements based on the table of values you provided in your earlier post. It turns out, it works very well! Great job with getting those angle values! It must have taken you a lot of time. You can download your attached model below.
When I said the hand was too unstable, I meant the MSPhysics version of a hand, not the real one. I apologize if you misunderstood and took it as an offence. In MSPhysics, a hand with 22 servos will not work well. It will be very unstable. Your guitar, however, requires only two servos; one for the arm and the other for the wrist - and it is very stable. So anyway, download the model below and see how it goes. Later, we could create an emulator that would play the real midi notes for the Blowin in the Wind song.
Regards,
Anton

Thanks, Istvan. Now it works like desired. Much joints for a little candlelight...

Hi,
I have a problem with gears using MSphysics. Is there any way how to fix it?Hi, Jakub,
If you enable the collision wireframe for your model, which can be done by opening MSPhysics UI, activating the Simulation tab, and, enabling the Collision Wireframe, you will see that the collision generated for the gears is improper. All sub collisions of dynamic (movable) shapes must consist from separate convex sub-groups. That said, your gears are concave. To fix it, either split the teeth in separate sub-groups/components, or use this plugin to draw gears instead: http://sketchucation.com/forums/viewtopic.php?t=46319

Faust07,
There are better ways for doing a candlelight. You could use particle effects or have a sequence of fire models that would hide unhide at a particular frame, that is, a repeating animation. The particle effects is the best approach as it always unique and easier to make. Besides you could also add a trailing smoke. An example is attached below.
Regards,
Anton
-
Anton_S, thanks for fast response. I'll try it.
-
Hi, Anton. Thank you very much. Again a great example of the particle effect and of a script to learn efficient programming. If we could do the smoke with emitters then there is a chance to render the simulation of the candle.

Have found a solution for the problem of SketchUp 2017 animation export of SketchUp 2016 MSPhysics models. Start SUp 2017 and import the SUp 2016 MSPhysics file with the .skp-import funktion. All scene data with layers, stiles, shadows etc. are lost, but the export of animations even of large models works. To open a SUp 2016 MSPhysics model directly and export the simulation from Replay brought the incomplete images. The underlying cause of the problem I could not find unfortunately...

Please, take a look at the following example.
The study of this example may help you with the problem of collision with the group and the subgroup.Chri

After tests with the late discovered Cenvexify (Fredo6 - Fredo Tools) here some problems with the relatively large torus segments with the usual MSP user interface settings.

Hello Faust07. I copied the slices into a new model and it works well. Always try this solution in such cases.
-
Thanks again, Istvan. Good to know. It seems to be a similar problem as the frame export in MSP Replay in SUp 2017 using SUp 2016 models. The solution was to copy the content or to import the model into a new model.
BTW, thanks for your shape loader extension!

Hi Anton,
during extensive physics calculations, MSPhysics reduces interim phases during image reproduction. Partially over 5 frames, the content remains the same. This can lead to pretty jerky videos. It would be helpful if this setting, at least for exporting the images in Replay, could be turned off? -
Hello all,
i'm new to msphysics and intermediate at sketchup 2016, and can't get my model to work the way i want.
Is there someone who can point me in the right direction???I like to reproduce this type of device and then make it animate in sketchup.

http://4.bp.blogspot.com/-4t0Ghm1M8VQ/Vh1EDse0mTI/AAAAAAAAAKo/Yo5RzwcT2xs/s1600/HU_1.pngFor now i have made some parts already but i want to begin animating already, but can't get it to work.
Someone who wants to help.
I need the parts to be connected and when a cylinders move like a slider, the rest of the parts have to follow.Kinde regards and thanks,
Bert.
