VSG-001

VulkanSceneGraph (VSG), is a modern, cross platform, high performance scene graph library built upon Vulkan

VSG 是一个基于vulkan的现代的、跨平台的高性能场景管理库

VSg特性：

• 使用C++17作为c++规范编码，
• 支持 CppCoreGuidelines
• 支持 FOSS Best Practices.
• 使用MIT License开源协议发布，商业友好
• 跨平台

VSG快速编译

先决条件:

• C++17 compliant compiler i.e. g++ 7.3 or later, Clang 6.0 or later, Visual Studio S2017 or later.
• Vulkan 1.1 or later.
• CMake 3.7 or later.

The above dependency versions are known to work so they’ve been set as the current minimum, it may be possible to build against older versions. If you find success with older versions let us know and we can update the version info.

Download VulkanSDK from LunarG, unpack into local directory and set VULKAN_SDK environment variable to the include/lib directory within it. For Linux it would typically be along the lines of:

export VULKAN_SDK_VERSION=1.2.162.1
export VULKAN_SDK=${PWD}/VulkanSDK/${VULKAN_SDK_VERSION}/x86_64

mkdir VulkanSDK
wget https://sdk.lunarg.com/sdk/download/${VULKAN_SDK_VERSION}/linux/vulkansdk-linux-x86_64-${VULKAN_SDK_VERSION}.tar.gz -O VulkanSDK/vulkansdk-linux-x86_64-${VULKAN_SDK_VERSION}.tar.gz
tar zxf VulkanSDK/vulkansdk-linux-x86_64-${VULKAN_SDK_VERSION}.tar.gz -C VulkanSDK/

Once you’ve downloaded and unpacked the VulkanSDK you’ll want to put VULKAN_SDK into your user environment variable setup so that CMake’s find_package(Vulkan) can find the VulkanSDK’s location.
