  Dialogs, StdCtrls, XPMan, Buttons, ExtCtrls;

    че не понятно? в TTimer идет перемножение матриц. Так вот из-за этого должно происходить вращение, а оно не происходит. Почему???

    тс, если хочешь получить ответ - относись с уважением к публике. если тебе начхать на тех, кто может тебе помочь, то вполне резонно ожидать такое же отношение к тебе...
