Mesh/Un-Static Mesh Feature Request

You can embed images in the forum posts here. And I would suggest dropping that hosting service. Not only does the username/password box popup. But to actually view one of the pictures it opens 4 browser tabs and a popup. Ug.
Moving meshes are not possible with this physics engine. You need to break the model into convex pieces. If want to make a bowl shaped object that moves you need to make it out of a bunch of convex facets and the make them a group. I think there are a few like that on 3dwarehouse.

Darn. Thanks for the speedy reply. I was hosting those on my home pc and still haven;t gotton and the bugs worked out.
Another question, Would it be bossible to build a screw that could be screwed into something that has a similar thread pattern?

Thats your own machine?? Its generating popups like mad.
Find the edit button on your post and remove those image links.

Yeah, it's just annoying, please, do something about it.

I confirm

Every new user asks this, including me. Like Chris said, It's not possible with the Newton Physics engine, which SketchyPhysics uses. He can't edit the engine, so we can't have 'moving meshes' (They're actually called concave hulls).But, seriously, remove the embedded images, and the links. Upload your pics and files straight from your computer, into the post, using the forum's system, and place them inline.

Thanks. I guess I will need to find another way to do this. I am very sorry about all the popups. They didn't happen on my computers. I didn't see that i could add an attachment at the botton. Thanks for the info.

Wacov, i'm not sure you can call it a concave hull. If it just read concave, then it wouldn't register any convex faces. i think it is impossible to have a fully concave object. even a bent face is still convex. I don't exactly get why there can't be a movable mesh, because a group of multiple facets is more complicated then a mesh of identical polygons. those facets are components, and the more components you have, the slower it gets. Could there be some other physics engine alternative, like a plugin engine that can be switched from the newton to the other?

The physics engine does not allow concave because it is very difficult (slow) to determine if concave objects collide. It wouldn't really be feasible to change out the physics engine at this point. I would have to start over. Sorry.

No, it's definately a concave hull... don't ask me why. Newton Dynamics isn't the most amazing engine in the world, but it's free and gets the job done. And, like Chris said, there's no way it's changing.

I have gotten it where a pin will fall into a shape and can be moved. Well sorta. The pin doesn't stay in there very well if i drag it around too fast( make sudden movements) and if I stack the blocks on top of each other, they just fall into the one below it. And they go through the floor some if they aren't flat on it. I have attached my model. Ya, I found the attachment button.
Just press play to see what i mean. So please tell me what I need to change.
