From 9b551d5cbcaf71a8c39bbf7e886290649aed4799 Mon Sep 17 00:00:00 2001 From: Kahrl Date: Sun, 2 Nov 2014 03:47:43 +0100 Subject: Implement WieldMeshSceneNode which improves wield mesh rendering - Don't create and cache an extruded mesh for every (non-node) item. Instead use a single one per image resolution. - For cubic nodes reuse a single wield mesh too - Improve lighting of the wielded item - Increase far value of wield mesh scene camera, fixes #1770 - Also includes some minor refactorings of Camera and GenericCAO. --- src/util/numeric.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/util') diff --git a/src/util/numeric.h b/src/util/numeric.h index ee8fea8cf..e7fdc2599 100644 --- a/src/util/numeric.h +++ b/src/util/numeric.h @@ -361,5 +361,10 @@ inline float cycle_shift(float value, float by = 0, float max = 1) return value + by; } +inline bool is_power_of_two(u32 n) +{ + return n != 0 && (n & (n-1)) == 0; +} + #endif -- cgit v1.2.3
