通过shape创建几何实体
概述
本教程提供了Render SDK基于Shape数据创建实体的使用教程。
前置条件
如果未初始化SDK，需要通过以下代码初始化
//创建sdk组件
//创建实体Render
auto mRender = mRenderComponent->CreateBasicRender();
AMCAX_RENDER_API std::shared_ptr< IRenderComponent > CreateRenderComponent(QWidget *parent)
Create Render Component
通过Shape创建实体示例
本示例通过加载Shape创建实体。
mRender->cameraManage->ResetCamera();
mRender->entityManage->DoRepaint();
通过json文件创建实体示例
本示例通过加载json文件创建实体。
