Albeit prior to 1.1 you couldn't use glVertexPointer and friends... Not to mention buffer objects... (Albeit I'd say you really should avoid it usually in any case, it will just get converted to float somewhere. Unless your data naturally comes as doubles, so it has to be converted somewhere no matter what.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
