Angular Collision causes astroids to orbit ( 0.3.4 build 967 )

(1/4) > >>

Recon:
Version: 0.3.4 build 967
Reproducibility: Always.

Abstract: Angular Collision causes small asteroids to orbit a point instead of rotating around its axis.


Description:
Strike a small asteroid off center, it start moving but also start orbiting a point that is outside its structure. Seems that instead of spinning around it's center of gravity it will start an orbit around another point!

System:
Windoze XP Pro sp2
Pentium 4 CPU 2.4Ghz
1024 MB Ram.
GeForce 6600 LE ( 8.1.8.5 Driver )

Morgul:
This is also a known defect. The physics actually are correct in this: the center of mass for that object is the center of the model. When that model was exported, the center of the object was rather far from it's center. However, maybe this bug report will make us a little less lazy... and get us to fix it.

ryguy_1617:
Yeah. Maybe.  ;)

Caenus:
You oughta plug in the dimensions into the centroid of mass equations, that'll give you exact coordinates in three dimensional space.

Rosencrantz:
I just verified the orbiting. Yeah, it's pretty weird. There some oddities in the mechanics of the way the asteroid was orbitting that I'll have to look at it and think about it some more. I'll post some more on it after that though.
