Open the media folder of your extracted Irrlicht package.

Copy sydney.md2 and sydney.bmp to where the executable of your new application is:

Add the line ISceneManager* smgr = device->getSceneManager(); directly after where we create our instance to the video driver.

To actually load a mesh, insert IMesh* mesh = smgr->getMesh("sydney.md2").

Now that our mesh is loaded, we still can't see our mesh. We need a node to display the mesh in our scene. Let's create one by adding this code: IMeshSceneNode* node = smgr->addMeshSceneNode(mesh).

Our node is added to the scene, but we need to adjust the camera to be able to actually see the mesh. Add this line: smgr->addCameraSceneNode(0, vector3df(0, 30, -40), vector3df(0, 5, 0)).

Add the line smgr->drawAll(); into our "game loop" between the beginScene() and endScene() function.

Your complete source code should look like this

#include <irrlicht.h>
using namespace irr;
using namespace core;
using namespace video;
using namespace scene;
#if defined(_MSC_VER)
#pragma comment(lib, "Irrlicht.lib")
#endif
int main()
{
IrrlichtDevice* device = createDevice(EDT_OPENGL, dimension2d<u32>(640, 480), 16, false, false, false, 0);
if (!device)
return 1;
IVideoDriver* driver = device->getVideoDriver();
ISceneManager* smgr = device->getSceneManager();
IMesh* mesh = smgr->getMesh("sydney.md2");
IMeshSceneNode* node = smgr->addMeshSceneNode(mesh);
smgr->addCameraSceneNode(0, vector3df(0, 30, -40), vector3df(0, 5, 0));
while (device->run())
{
driver->beginScene(true, true, SColor(255, 255, 255, 255));
smgr->drawAll();
driver->endScene();
}
device->drop();
return 0;
}
