hi all,
i'm having problems with the physics system again.
in fedora 12 even the simplest physics script with collisions works
strange. if collision occurs the objects disappear. two colliding cubes
or a cube with a ground plane show the same behaviour.
(clear)
(ground-plane #(0 1 0) 0)
(active-box (build-cube))
another problem which seems to appear when ode is compiled with double
precision (tested in osx). i have this simple script which explodes an
object:
(clear)
(hint-none)
(hint-wire)
(backfacecull 0)
(collisions 1)
(gravity #(0 0 0))
(let ([s (build-sphere 10 10)])
(with-primitive s
(for ([i (in-range (quotient (pdata-size) 3))])
(let* ([t (build-polygons 3 'triangle-list)]
[p0 (pdata-ref "p" (* i 3))]
[p1 (pdata-ref "p" (+ (* i 3) 1))]
[p2 (pdata-ref "p" (+ (* i 3) 2))])
(with-primitive t
(pdata-set "p" 0 p0)
(pdata-set "p" 1 p1)
(pdata-set "p" 2 p2))
(active-box t))))
(destroy s))
with float precision it works, but with double precision it crashes
fluxus. could someone test if it works please? do you have any
suggestions how to track down these problems?
best,
gabor
