Oh yea - there is an indexing bug in the FAST TRISTRIP logic that
somehow never got changed even though the fix was in several of
my submissions
maybe this has finally reared it's head if the scenery has hit a
tristrip but I didn't think we were actualy using any yet
easiest to check by just falling back to the 'slightly' slower version
by changing the lines in
void FGHitList::IntersectBranch( ssgBranch *branch, sgdMat4 m,
sgdVec3 orig, sgdVec3 dir )
....
- GLenum primType = ((ssgLeaf *)kid)->getPrimitiveType();
- IntersectLeaf( (ssgLeaf *)kid, m, orig_leaf, dir_leaf, primType );
to
+ IntersectLeaf( (ssgLeaf *)kid, m, orig_leaf, dir_leaf );
