From 59c6358dbcfbb70e3796fef5d3063ffb9491ae8b Mon Sep 17 00:00:00 2001 From: Xerxes Rånby Date: Thu, 20 Sep 2012 13:20:13 +0200 Subject: Improve frame rendering smoothness in src/demos/es2/RawGL2ES2demo.java by using Animator instead of FPSAnimator. Calculate the time deltas for the theta movement using milliseconds passed between two frames.
