Newton 2.0 - RayCast bug

[sea]

That looks strange, I'd never noticed this bug . Especially these hit-points distanced far away from the "source".

I still hope i'm doing something wrong, but i followed the manual on raycast functions and i dont think this worked like that before, but i'm not completely sure, i'm waiting for julio to test the demo and see what's going on.

Edit: the bug i have started to happen in beta19.

That is a strictly beta 19 bug.
It is fixed now, can you download beta19 and try again, please all ray cast bug should be fixed now

I downloaded beta 19 and tried out the demo, everything works except when I go to the ray cast car scene. It works 100% under x86 mode, but when the simd mode option is used, the car's wheels seem to bounce around randomly, and the ray cast picking for the car seems to not work. Switching to the x86 mode immediately fixes the car, so I'm assuming there is something going on with the ray casting and simd mode. This is beta 19, downloaded a few minutes ago. (AMD Athlon64 X2 4800+, if it matters - beta18 ray casting worked fine in simd mode)

Thre is a bug on ray cast that I am trying to find. It not a simple Bug
teh one repeort by Sea is fixed, but there are few other I introduced with the last optimizations.
I am working on it.

Agi had you seem any speed improvements, special in large seems?
I made some big optimizations on teh parallel solver, no is solver everthong in paralell.
It should also make the single thread mode better.

bingo thats where the bug is in beta 19.
Good observation Masters Agi.

The new dll fixes the problems and all raycasts appear to work properly here's a screenshot of it all working properly:

A shout out to master Agi,

Master agi cna you please try again.

Hey Agi speaking of ray tracing, i think what Master Delfy is doing is ray tracing his world for teh eye point of the NPCs.

Except that my NPCs have a 360 degree panoramic view

[agi_shi]

Yup, works 100% in both simd and x86 now

I sent a request for beta19 so I will test it by myself in my game. I'll also check out the optimalizations.

It's the same link as always, just updated.

OK, I got it, the bug I posted is fixed, but I saw another one with tree collision (horizontal face - ray cast seems to ignore it). Everything else works ok and a little bit faster. I hope that the new ray cast bug is what Julio is working on.

I had the same problem when the first distant hits problem was fixed, but before i got the very latest fixed dll which was a separate link, maybe you didn't update the full sdk archive yet? sea does use linux version of the library.

[Julio Jerez]

I have no make teh linux buidl yet,
I will try the this afernoon.
