[osg-users] osgtessellate example question

hi,

i have a question concerning the "osgtessellate" example. why vanishes the TRIANGLE_STRIP primitives constructed in the function "makePolsTwo()" after "TESS_WINDING_NEGATIVE?

as far as i understand, a similiar primitive, constructed in "makePols()" is created with same settings, like the one in "makePolsTwo()", and it also (temporaly) disapperars while "TESS_WINDING_ABS_GEQ_TWO". but when the tessellation cycle starts again, the one from "makePols()" is there again, the other one from "makePolsTwo()" isn't.

thanks in advance,
christian
