noticed RE_rayobject_raycast will often divide by zero, perhaps this
is ok but seems like it could lead to problems,
is this intentional?
---- rayobject.cpp:383
isec->idot_axis[i] = 1.0f / isec->vec[i];
----
int RE_rayobject_raycast(RayObject *r, Isect *isec)
{
int i;
RE_RC_COUNT(isec->raycounter->raycast.test);
/* Setup vars used on raycast */
isec->dist = len_v3(isec->vec);
for(i=0; i<3; i++)
{
isec->idot_axis[i] = 1.0f / isec->vec[i];
isec->bv_index[2*i] = isec->idot_axis[i] < 0.0 ? 1
: 0;
isec->bv_index[2*i+1] = 1 - isec->bv_index[2*i];
isec->bv_index[2*i] = i+3*isec->bv_index[2*i];
isec->bv_index[2*i+1] = i+3*isec->bv_index[2*i+1];
}
