把setPixelFormat、初始化glew、创建GL 4,2 context等操作封装到MFC类OpenGLWidget里了。使用步骤：
1. 把OpenGLWidget.h和OpenGLWidget.cpp包含在项目里面。
2. 继承类OpenGLWidget，实现两个虚函数：Initialize()[负责加载数据]、RenderScene()[负责渲染]两个函数。比如下面的LeftWindow类：
#pragma once #include "OpenGLWidget.h" #include <Cameras/phc.h> #include <OpenglWrappers/DemoMeshes/BlinnPhongMesh.h> class LeftWindow : public OpenGLWidget{ redips::PhC *m_phc = new redips::PhC(45, 1.0f, 0.1f, 10000); redips::BlinnPhongMesh* m_mesh = nullptr; public: LeftWindow(){} ~LeftWindow(){
delete m_mesh; delete m_phc;
} bool Initialize(){ m_mesh = new redips::BlinnPhongMesh(new redips::Triangles("E:/Documents/models/Effier/new_iffier.obj"));
auto heart = m_mesh->model_ptr()->aabb_R().heart(); m_phc->lookAt(heart + redips::float3(0, 0, 500), heart, redips::float3(0, 1, 0)); return true; } void RenderScene(){ m_mesh->uniformFloat3("lightColor", redips::float3(1, 1, 1)); m_mesh->uniformFloat3("lightPos", m_phc->pos()); m_mesh->uniformFloat3("cameraPos", m_phc->pos()); m_mesh->uniformMat44f("model", redips::Mat44f::eye().ptr()); m_mesh->uniformMat44f("projection", m_phc->glProjection().ptr()); m_mesh->uniformMat44f("view", m_phc->glView().ptr()); m_mesh->draw(); } };
3. 将下面代码添加到OnInitDialog()函数里，即在当前对话框里创建了一个OpenGLWidget
m_leftWindow = new LeftWindow; m_leftWindow ->Create(NULL, NULL, WS_CHILD | WS_CLIPSIBLINGS | WS_CLIPCHILDREN | WS_VISIBLE, CRect(0, 0, 800, 800), this, //this is the parent 0);
