#80 Capsule-Box Collision bug

[Georg Martius]

I noticed an incorrect collision handling of capsules with boxes, if the
capsule is penetrated into the box further than the radius in either
direction. All Capsules move to the SAME direction, i.e. also get sucked
into the box. It is a severe bug because it causes regular penetration or
blockage with fast objects and/or soft collision.
See mailing list screenshots and patches.
Initial Patch produces bad normals here is an updated version

[Georg Martius]

patch for svn rev 1840

[Georg Martius]

new patch for svn rev 1840 (instead of previous one)

[Georg Martius]

new patch that simply considers the capsule as a box if it is deeply penetrated. This works
great and solves all problems because the box-box collision routines are well
tested.

Although it's not the best solution, the patch was applied on rev 1840.

Really applied on rev 1883.
