离线简模插件

开发步骤

1. 下载SDK包，解压获取SDK库，下载地址请参见SDK下载：离线简模插件。
2. 通过CMake等构建工具集成简模SDK库文件。

   cmake_minimum_required(VERSION 3.0)
   project(main)
   set(CMAKE_CXX_STANDARD 11)
   link_directories("${CMAKE_CURRENT_SOURCE_DIR}/lib")
   add_executable(main main.cpp)
   target_link_libraries( main
                          PUBLIC)

   说明

   • 当前离线简模插件仅支持64位系统。
   • SlimMesh.dll与main可执行文件需要置于同一目录运行。

3. 构造模型顶点信息数据，调用简模算法接口，获取简模后的模型数据。
