Method Detail

collide

public int collide(Geom o1,
                   Geom o2,
                   int flags,
                   ContactGeom[] contacts,
                   int contactIndex,
                   int skip)

Finds contact points between a pair of triangular meshes.

Specified by:

collide in interface Collider

Parameters:

o1 - one triangular mesh

o2 - the other triangular mesh

flags - is currently ignored

contacts - an array into which to store contacts found. The caller may pre-allocate the array entries or leave them as null.

contactIndex - the index of the first element in contact at which a contact should be stored.

skip - is unused

Returns:

the number of contacts found.
