From a88aebe8ccf23778a0e82504aadd9c87b09d20bd Mon Sep 17 00:00:00 2001 From: Ivan Furs Date: Wed, 3 Jun 2015 16:34:45 +0200 Subject: [PATCH] evas: for aabb add interpolation frame when base frame is not found Summary: Old algorithm searched specified frame of the base frame and when it could not find the specified frame it ignored. So the bounding box was not synchronized with the object. New algorithm always returns specified base frame or frame interpolation between the nearest base frames. That does synchronizes mesh object and his bounding box.
