camera problems, again

well, for a school project i gotta do some basic line and circle drawing alogitms and basic 3d, like transformations, viewing (camera) transform and perspective/paralel projection. projecting my world coordinates works ok, but when i add a view transform (world->cam space), the thing gets messy... and i''m loosing patience i admit, view projections are still totally not clear to me, but i''d like to solve it once and for all... so, anyway here''s the whole project (msVc6). note that code is somewhat messy LINK: http://vesoljc.tripod.com/temp/temp.zip so if any of u, has some extra time and is willing to help poor me, me would be very grateful...
