Pangolin 6: Simple Scene
# Prepare
https://github.com/uoip/pangolin/blob/master/include/pangolin/scene/renderable.h:
```cpp
Renderable& Add(const std::shared_ptr& child)
{
if(child) {
children[child->guid] = child;
};
return *this;
}
```
# Source code
```cpp
#include <pangolin/pangolin.h>
#include <pangolin/scene/axis.h>
#include <pangolin/scene/scenehandler.h>
int main( int /*argc*/, char** /*argv*/ )
{
pangolin::CreateWindowAndBind("Main",640,480);
glEnable(GL_DEPTH_TEST);
// Define Projection and initial ModelView matrix
pangolin::OpenGlRenderState s_cam(
pangolin::ProjectionMatrix(640,480,420,420,320,240,0.2,100),
pangolin::ModelViewLookAt(-2,2,-2, 0,0,0, pangolin::AxisY)
);
pangolin::Renderable tree;
tree.Add( std::make_shared() );
// Create Interactive View in window
pangolin::SceneHandler handler(tree, s_cam);
pangolin::View& d_cam = pangolin::CreateDisplay()
.SetBounds(0.0, 1.0, 0.0, 1.0, -640.0f/480.0f)
.SetHandler(&handler);
d_cam.SetDrawFunction([&](pangolin::View& view){
view.Activate(s_cam);
tree.Render();
});
while( !pangolin::ShouldQuit() )
{
// Clear screen and activate view to render into
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
// Swap frames and Process Events
pangolin::FinishFrame();
}
return 0;
}
```
