Thread Hijacker much -.- How about commenting on my model, and make your own thread. Don't mean to be too harsh...

@kprice said: It seems something like "linear aerodynamics" should be manageable. Lift = lift_constantangle_of_attackvelocitywing_area, in direction perpendicular to velocity Drag = drag_constantangle_of_attackvelocitywing_area, acts in direction parallel to velocity. Lift_constant and drag_constant should be functions of angle of attack, for example if Lift_constant goes to zero at some maximum angle of attack it will represent stalling of the wing. This is somewhat similar to a magnet whose force depends on velocity of the object, instead of the distance to another object...I guess I need to peek at the magnet code. Kirk You sound like you know what you are talking about... It went over my head. dVector delta = body->location - magnet->location; dVector dir = delta.normalize(); dVector force = dir.Scale(body->mass * magnet->strength / delta.squaredLength()); NewtonBodyAddForce(body,force); Its also easy to get the body linear and angular velocities.

Sorry to hear about the accident -- I couldn't imaging not having an useable mouse hand. Thanks for the update -- I'm thrilled to hear SP finally going to make it to the Mac. Thank you for you efforts. More on the point, friction coefficients would be a welcome and powerful addition to SP. I could almost imagine eventually seeing a feature like quick-and-dirty CFD. That would be cool.

thanks

Hi Platypus5, you are right and sorry for not removing my post, in the meantime i have askes sort of like the same question somewhere else on the forum and got some worthwile responses. Thanks, Fred.

Hi Alex, What properties did you assign to the noodle shape? Thanks, Jeff

Hello All, especially Sean, I am also a woodworker and would like to use SketchyPhysics and SketchUp to "prototype" various designs. I find that building a 3D item to an exact size and being able to place it exactly where I want is a royal pain. I'm probably missing some crucial information. How do you place and size items? I'd love to see a 2D to 3D tool for creating individual items for assembly in SketchUp - even a text (XML) to SketchUp converter (which I'm willing to code if someone gives me the skp structure). Thanks! Bill

Hello All, Among other things, I'm a professional content developer and it is my primary responsibility at my day job to build tutorials and other educational material. I'm willing to donate a bunch of hours to get a meaningful tutorial put together provided that I can set up some phone conversations/web meetings (I have the tools) to discuss. Let me know how the "owners" would like to proceed...

They wont damage anything. But they wont work in 3.0.

Okay thanks, it works great .

I take it back. SketchyReplay does still work (sort of). You said you got it recording. The problem is that the data is stored in the object and when the simulation is reset those changes are erased by the undo system. If you want to use your hack to mess with SketchyReplay also comment out the abort_operation command in resetSimulation(). Now after a simulation you can try the replay button. I might resurrect SketchyReplay in 3.0. I had forgotten that it was a pretty cool feature. It even had some editing including cuts and camera angles. Check out one of the first SP videos I posted. [flash=648,480:32a98dnt]http://youtube.com/v/cPwyZQukvPU[/flash:32a98dnt] Its really a SketchyReplay example. All of the editing like when the camera angle changes and how it tracks is all just SR commands in the page descriptions. And the rewind at the end is not a video rewind but a rewind of the animation in sketchup.

Looks nice maybe you should edite the first post, and change the thread name to: Post your WIPs Here. I think that adding caps and multiple exclamation marks could be a bit distracting...

HEHE All of the models here are posted by me!!!(yes i have joined and i look forward to increasing my potential and other's.)

What i do to avoid the "ignore" control: use a powered hinge instead of the reversed motor, then play around with the accel of the hinge until the wheels don't move at 0.5.

That Looks So Cool. I really liked the volcano/eruption/whatever thing

So, my guess is that it will be released early January.

Now, If I remember correctly, all you have to do is move the Sketchyphysics folder, sketchysolids.rb and the sketchyphysics.rb files. Worked for me.

Thank You but where the .... is original sketchyphysics to download!

Both should allow rotation perpendicular to the joint axis. A ball joint should also allow rotation around the joint axis, but a universal should transmit torque around the joint axis. Take a look at http://sketchup.google.com/3dwarehouse/details?mid=69d447c5714436b4d1246dc603255322, in which I found that, instead, ball joints are transmitting torque and universals aren't.

sounds good. video looks good also.... although i would much appreciate, something comparable for the standalone rendering software kerkythea. well, we all will just have to wait for things like these to be developed. maybe blender will do the trick... thx 4 the advice
