    who knows maybe i'll complete it tomorrow !

    and lets remember that one of the Graals of guitar props is dynamic guitar straps ... which is somewhat related to physics engines

    Oh I'll go along with that ... "very related" ;-)

    Yay ! we got hinge behavior !

    ( though the hinge axis is not where it was expected

    --

    figure 2 looks like the position of the axis is relative to the hinge'd body

    Amy completely confident that the twin-hinges experiment will proceed without a hitch

    1 hinge because with 2 hinges it got interlocked i guess

    i'll try to post it very soon, i want to make it modular enough

    i have to rename some materials

    fix issues with the roof tiles

    the whole thing is 34K polygons most of it in the cute roof tiles ... so i may make the roof tiles removable

    ----

    redone the animation with a less brutal push-cube :)

    ---

    for the record this is a replica from memory of the swing our friend/neighbor
    had at our summer cabin, it was facing a small lake, maybe 20 ft from the shore
    and there was a circle of rocks to make fires in front of it
    and the place didnt have too many mosquitoes in the evening

    the initial release will (probably)

    have the physics primitives
    cube cylinder box capsule cone

    and the constraints
    hinge, point, 6 D.O.F, slider, twist-cone ( for rag-dolls)

    Amy as the bat girl vs the tower of ... something probably nefarious

    the tower of doom and gloom

    which is unexpectedly white

    Strike one - the tower of gloom and doom explodes before Amy has a chance to hit it

    gotta rebuild a tower with air gaps between the blocks

    I think the weasels ate the tower before our girl could hit it! lmao

    Amy makes it to first base ! :)

    maybe the bat moves too fast

    i'll increase its mass and spheres of influence

    also if the simulation was longer the tower would probably have crumbled

    I hadn't noticed that, Eustace. She is REALLY powerful.

    Top of the tower begins to fall before she begins to swing.

    in the early tests the tower exploded or sank before she could hit it
    so this was an improvement
    next tests i should figure how to get stable structures

    Video woo hoo!

    i gathered recent Amy VS The Tower of Gloom and Doom tests

    and made a YT video

    --

    Fig 1 - ( again ) working on making sure rotations make sense ... they seem to ... but why is that block refusing to jump off the cliff ... it became self aware obviously, John Connors

    ( later that night ) actually the culprit is quaternions with near-zero rotations ...

    physics project news

    minor progress, the script can now handle objects that don't have their origin and center-of-volume match

    in this animation, still only 1 hinge being simulated, the other hinge is handled by a custom script

    things i had to contend with :

    i have to hand over to the physics-engine the positions of the hinges ......

    in the reference-frame of the constrained object

    and this means, the rotations too

    so the hinge is not at ( 0, 0.5, 0.867 ) from the cube's point of view

    it's at ( 0, 0, 1 )

    it also means the Hinge Axis needs to be given from the cube's point of view

    it gets complicated sometimes
