SettingManager class. This class loads and writes the settings and manages the options. The class makes use of irrMap which is a an associative arrays using a. This Tutorial shows how to speed up rendering by use of the OcclusionQuery feature. The usual rendering tries to avoid rendering of scene nodes by culling. This example show Hello World for Windows mobile. It compiles on other platform too. The only differences between the original examples are. You need a GUI.

To be able to do collision with the terrain, we create a triangle selector. This Tutorial shows how to move and animate SceneNodes. If you want to know what triangle selectors do, just take a look into the collision tutorial. This is useful if you want to extend the render techniques of the Irrlicht Engine.
The only parameter we use is a file name to the heightmap we use. First, we add standard stuff to the scene: One occluder, one occluded.

The Irrlicht Engine uses wide character strings when displaying text. One can, based on this number, judge if the scene node is visible enough to be rendered, or if the node should be removed in the next itrlicht.
Now we only need a camera to look at the Quake 3 map. First, we draw the scene, possibly without the occluded element. This tutorial shows how to use one of the built in more complex materials in irrlicht: A nice irrlicht engine logo, a small help text, a user controlled camera, and we disable the mouse cursor.
Here we create the occlusion query. The first texture will be repeated only one time over the whole terrain, and the second one detail map 20 times. Win32 window This example only runs in Windows and demonstrates that Irrlicht can run inside a win32 window. We include the needed tutprial files and create an event listener to listen if the user presses a key: IMeshSceneNodewhich would always draw the complete geometry of the mesh, without optimization. To be able to use the Irrlicht.
The most important function of the engine is the createDevice function. SMeshHandling This tutorial explains how to manually create meshes in Irrlicht.

We also write the current frames per second and the name of the driver to the caption of the window to examine the render speedup. The terrain renderer loads it and creates the 3D terrain from it. To make the terrain look more big, we change the scale factor of it to 40, 4. Tutorizl supports special light setup via light managers. To show something interesting, we load a Quake 2 model and display it. But if you like, you can also include the namespaces like in the previous example.
It will also show how to use fog and moving particle systems. Because the level was not modelled around the origin 0,0,0we translate the whole level a little bit. The beginScene call clears the screen with a color and the depth buffer, if desired.
On Windows platforms, we have to get rid of the console window, which pops up when starting igrlicht program with main. SplitScreen This tutorial presents usage of split screen setups. You dont need any experience with shaders to use these materials in Irrlicht.
We have done everything, so lets draw it.
With the endScene call everything is presented on the screen. This gives the GPU more time to pass back the results without flushing the render pipeline. ISceneNode level using the tutoria irr:: This tutorial shows how to load a Quake 3 map into the engine, create a SceneNode for optimizing the speed of rendering and how to create a user controlled camera.
The mouse cursor needs not be visible, so we hide it via the irr:: We run the device in a while loop, until the device does not want to run any more. We construct a simple mesh viewer using the user interface API and the scene management of Irrlicht. Occlusion queries check exactly that. This tutorial explains how to manually create meshes in Irrlicht.
To be able to do collision with the terrain, we create a triangle selector. Lets start like the HelloWorld example: The text is placed tjtorial the position 10,10 as top left corner and ,22 as lower right corner. The start of the main function starts like in most other example.
