irrlicht/include/ISceneManager.h
cutealien a67b616fc9 Add another render pass ESNRP_GUI which is drawn last and is p.E. useful for rendering gui nodes in the scenemanager. 
UI and scenenodes are often connected. And while it was possible to work around this already by using custom draw functions
or deriving from gui and scene-nodes at the same time, it did already lead a few times to uglier code for me. 
So I guess adding one more pass to the engine has it's uses.

/** All Scene nodes can be created only here. There is a always growing
list of scene nodes for lots of purposes: Indoor rendering scene nodes
like the Octree (addOctreeSceneNode()) or the terrain renderer
(addTerrainSceneNode()), different Camera scene nodes
(addCameraSceneNode(), addCameraSceneNodeMaya()), scene nodes for Light
(addLightSceneNode()), Billboards (addBillboardSceneNode()) and so on.
A scene node is a node in the hierarchical scene graph. Every scene node
may have children, which are other scene nodes. Children move relative
the their parents position. If the parent of a node is not visible, its
children won't be visible, too. In this way, it is for example easily
possible to attach a light to a moving car or to place a walking
character on a moving platform on a moving ship.
The SceneManager is also able to load 3d mesh files of different
formats. Take a look at getMesh() to find out what formats are
supported. If these formats are not enough, use
addExternalMeshLoader() to add new formats to the engine.

* not contain only one single mesh but multiple meshes
* and a whole scene setup with lights, cameras and mesh
* instances, this loader can set up a scene as

use setTarget, to fix the target the camera the camera hovers around. And setDistance
to set the current distance from that target, i.e. the radius of the orbit the camera
hovers on.

/** This FPS camera is intended to provide a demonstration of a
camera that behaves like a typical First Person Shooter. It is
useful for simple demos and prototyping but is not intended to
provide a full solution for a production quality game. It binds
the camera scene node rotation to the look-at target; @see
ICameraSceneNode::bindTargetAndRotation(). With this camera,
you look with the mouse, and move with cursor keys. If you want
to change the key layout, you can specify your own keymap. For
example to make the camera be controlled by the cursor keys AND
the keys W,A,S, and D, do something like this:
\code
SKeyMap keyMap[8];
keyMap[0].Action = EKA_MOVE_FORWARD;

//! Adds a terrain scene node to the scene graph.
/** This node implements is a simple terrain renderer which uses
a technique known as geo mip mapping
for reducing the detail of triangle blocks which are far away.
The code for the TerrainSceneNode is based on the terrain
renderer by Soconne and the GeoMipMapSceneNode developed by
Spintz. They made their code available for Irrlicht and allowed
it to be distributed under this licence. I only modified some
parts. A lot of thanks go to them.
This scene node is capable of loading terrains and updating
the indices at runtime to enable viewing very large terrains
very quickly. It uses a CLOD (Continuous Level of Detail)
algorithm which updates the indices for each patch based on
a LOD (Level of Detail) which is determined based on a patch's
distance from the camera.
The patch size of the terrain must always be a size of 2^N+1,
i.e. 8+1(9), 16+1(17), etc.
The MaxLOD available is directly dependent on the patch size
of the terrain. LOD 0 contains all of the indices to draw all
the triangles at the max detail for a patch. As each LOD goes
up by 1 the step taken, in generating indices increases by
-2^LOD, so for LOD 1, the step taken is 2, for LOD 2, the step
taken is 4, LOD 3 - 8, etc. The step can be no larger than
the size of the patch, so having a LOD of 8, with a patch size
of 17, is asking the algorithm to generate indices every 2^8 (
256 ) vertices, which is not possible with a patch size of 17.
The maximum LOD for a patch size of 17 is 2^4 ( 16 ). So,
with a MaxLOD of 5, you'll have LOD 0 ( full detail ), LOD 1 (
every 2 vertices ), LOD 2 ( every 4 vertices ), LOD 3 ( every
8 vertices ) and LOD 4 ( every 16 vertices ).
\param heightMapFileName: The name of the file on disk, to read vertex data from. This should
be a gray scale bitmap.
\param parent: Parent of the scene node. Can be 0 if no parent.
\param id: Id of the node. This id can be used to identify the scene node.
\param position: The absolute position of this node.
\param rotation: The absolute rotation of this node. ( NOT YET IMPLEMENTED )
\param scale: The scale factor for the terrain. If you're
using a heightmap of size 129x129 and would like your terrain
to be 12900x12900 in game units, then use a scale factor of (
core::vector ( 100.0f, 100.0f, 100.0f ). If you use a Y
scaling factor of 0.0f, then your terrain will be flat.
\param vertexColor: The default color of all the vertices. If no texture is associated
with the scene node, then all vertices will be this color. Defaults to white.
\param maxLOD: The maximum LOD (level of detail) for the node. Only change if you
know what you are doing, this might lead to strange behavior.
\param patchSize: patch size of the terrain. Only change if you
know what you are doing, this might lead to strange behavior.
