From e12c89e8c9896b2e5cdd70dbd2d2acb449ff4b94 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Sat, 13 Jan 2018 14:01:53 +0100 Subject: bullet: Streamline bundling, remove extraneous src/ folder Document version and how to extract sources in thirdparty/README.md. Drop unnecessary CMake and Premake files. Simplify SCsub, drop unused one. --- .../BulletCollision/CollisionShapes/btShapeHull.h | 61 ++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 thirdparty/bullet/BulletCollision/CollisionShapes/btShapeHull.h (limited to 'thirdparty/bullet/BulletCollision/CollisionShapes/btShapeHull.h') diff --git a/thirdparty/bullet/BulletCollision/CollisionShapes/btShapeHull.h b/thirdparty/bullet/BulletCollision/CollisionShapes/btShapeHull.h new file mode 100644 index 0000000000..e959f198b6 --- /dev/null +++ b/thirdparty/bullet/BulletCollision/CollisionShapes/btShapeHull.h @@ -0,0 +1,61 @@ +/* +Bullet Continuous Collision Detection and Physics Library +Copyright (c) 2003-2009 Erwin Coumans http://bulletphysics.org + +This software is provided 'as-is', without any express or implied warranty. +In no event will the authors be held liable for any damages arising from the use of this software. +Permission is granted to anyone to use this software for any purpose, +including commercial applications, and to alter it and redistribute it freely, +subject to the following restrictions: + +1.
