again :o(
I changed my code parts for using J3DBuffer's, but again I got a problem.
I have compared my code with the 'GeometryByReferenceNIOBuffer' Example and I
can't figure out any differences in principle..
code bellow works fine with useBuffers false, but setting it to true nothing is
rendered.. i played it bit with the code and noticed that
geomArray.getCoordRefBuffer() returns a null-reference.. but before setting
J3DBuffer everything is fine..
any ideas what I have done wrong ?
(also removed USE_COORD_INDEX_ONLY and set all indices, but didn't change
anything..)
greetings
