SketchyPhysics Alpha

Any other comments or feedback?

Has anyone used the SketchySolids toolbar? I am thinking that it is almost worthy of being a separate plugin.

Chris

Hi Chris,

I'll have to lock myself into a room for a couple
of hours with SketchyPhysics and get back on this
one.

Well I just want to say as everyone that this is a really amazing script, I have look around the different possibilities, there is alot that we can do and it realy increase the use of Sketchup, increase our ideas and help us more with our needs.
I know that this is just the begining, and I also know that it will only get better, i will be waiting for it.
I really want to thank you for sharing with everyone.
one question I have for now, is there a way to control how to "grab" the objects in a way that we can for example grab a cmu block and put it on an other one with presision. When I tried they seem to be floating in the air as I carry them? I will keep trying.

Again thank you very much for all the work.

Amazing stuff and great work.
After watching the videos
the possibilities are endless.

By default the object will try to move only horiziontaly. Hold down CTRL to drag up and down.

There is a tutorial of sorts here:

I am doing this but what i meant is that even when I lift up the object it is hard to control them, they are like hanging on a string and swinging as i move.

Oh, I see. I tried it so the object moved faster and it didnt work very well. The problem is the object flys around the scene too fast. Say you drag a cube from one side of the screen to the other. Depending on how far out you are zoomed the object can be moving hundereds of miles per hour. If it bumped into anything along the way that object would go flying.

Ill make it adjustable in a future version and you can try it.

And I agree, the controls could be better.

I found the controls pretty good, I got how to move stuff and throw stuff, and drop it. and I liked the bars...

I like this script so much, I thought I'd do a tribute...Indigo style!

That looks really cool! It will be nice when we can finally do physics and ray tracing in real time.

"sniff, sniff..........feeling sorry for myself............"

Thanks Chris, you have managed to make the one thing on the planet that makes me regret not having a PC.

Sure sounds like you guys are having a fun time...........

namza · 5 Nov 2007, 11:25

i did that funny work
you need the last version of sketchyphysics http://code.google.com/p/sketchyphysics/wiki/LatestVersion

why not run that Windows Emulator....?

Very cool. That is the simplest self moving machine I have seen.

i made it afer a lost of test. The problem is that now i CAN'T ( !!) reproduce this machine. It goes with join and groups but all depends of what do i have to join ans what do i have to group ...and in wich order .....

By the way. I see you made your track out of blocks. That is fine, but you can also just edit the floor. Any staticmesh (like the floor) can be edited at a per face level and will still work.

You can use the joint connection tool to examine the way the joints are connected. In this case each of the 3 cylinders is grouped with a hinge. And the bars are just connected to the hinges.

Joint connections can be confusing at first.

Chris,
That is nothing short of amazing. I'm awestruck. I'm curious as to why and what it took (in general terms) to create this.

Thanks Mark.

The why is because its fun. I like making things that actually behave the way you'd expect.

What it took was a good physics engine (newton) and a lot of work. I have been working on it on and off for over 2 years. Its currently around 10k lines of ruby but I have probably written and discarded 20k.

Some of that 10k is code that isn't even enabled yet. SketchyReplay for example records animations and features some non-linear editing. Here is an example. Note the camera behavior and the rewind stuff at the end.

So, I've set up a Sketchy Physics competition for anyone who is interested in modeling with Sketchy Physics.

Krisidious · 5 Nov 2007, 11:30

is there or could there be, a way to turn on a shader, that would shade or highlight the area in which SketchyPhysics was available with in the model.

know what I mean? there is an area in which the Physics work and one where it does not, I'd like to see that area...
