Graphics debug views
====================
There are some graphics debug views, to be used both by artists when developing,
and by users when reporting bugs.
These should be available in normal (non-artist) mode
to enable easier bug reports (go there, press this key, screenshot)
without requiring editing the UTF-32 config files (which is inconvenient, most editors
do not support that weird encoding).
They don't give gameplay advantages like the item keys, so there should be little harm
leaving them available. Accidental keypresses ought to be minimized by their location.
Home - wireframe view
End - mipmap visualization (is a texture too high or low resolution, red = too high)
Del - normal view
PgDown - SSAO view
PgUp - light view
Ins - shadow view
ScrlLock - displacement view

Graphics GSOC XML additions
===========================
This document will list in depth all new XML values added during the graphics GSOC, for use
by the blender exporter scripts.
Glow colors
-----------
The glow colors for nitro bottles and boxes are settable in stk_config.xml.
They are three-value RGB colors.
Example: <glow-colors nitro="0 0 255" box="255 0 0" />
Particle wind
-------------
Particles may be affected by wind. This is used with the snow particles.
Flips is a boolean controlling whether each particle will spin about its own two axis.
It is only applicable to symmetric textures, such as snow flakes.
Speed is a float in no real units.
Example: <wind speed="0.16" flips="Y" />
Forced bloom objects
--------------------
Any object may be marked as forced bloom. This will include the object in the bloom pass
regardless of its brightness.
Example: forcedbloom="Y" inside the <object> tag, in scene.xml.
Forced bloom objects may optionally include a multiplier, ranging from 0.5 to 10:
bloompower="2.5"
Glowing objects
---------------
Any object may be marked as glowing. The glow is a RGB value.
Example: glow="0 255 0" inside the <object> tag, in scene.xml.
Caustics
--------
A material effect, ie GE_CAUSTICS, to mark a texture as receiving caustics. To be used
for the ocean floor, puddle floor, etc.
Example: graphics-effect="caustics" in materials.xml.
Refractions/reflections
-----------------------
A per-object boolean flag, typically set for subsea windows or the ocean surface.
Example: displacing="Y" in the <object> tag in scene.xml.
Per-track tags
--------------
These are all specified inside track.xml, among the track's author, music, etc.
Cloud shadows
-------------
Boolean whether to have the sun blocked by cloud shadows, moving with the wind.
Disabled by default.
The effect is completely fake, doesn't correspond to any real or simulated clouds, but
nobody's checking, so it looks nice.
Example: clouds="Y" inside the <track> tag.
Bloom
-----
Boolean whether to enable global bloom for this track. Enabled by default.
Example: bloom="Y" inside the <track> tag.
Bloom threshold
---------------
Float that specifies the minimum luminance needed for a pixel to participate in the bloom.
The default is 0.75.
Example: bloom-threshold="0.75"
Lens flare
----------
Boolean that specifies whether a lens flare is shown when the player looks at the sun.
The strength and angle depend on the relation of the camera to the sun. Disabled by default.
Example: lens-flare="Y"
Dynamic shadows
---------------
Boolean on whether this track should use dynamic shadows. Enabled by default.
If disabled, the fallback fake kart shadows will be used.
Example: shadows="N"
God rays
--------
Boolean on rendering god rays when the player looks at the sun. Disabled by default.
Example: god-rays="Y"
Displacement speed
------------------
Float on the relative speed of any displacing objects in this level. Default 1.0.
2.0 = double speed, 0.5 = half speed, etc.
Example: displacement-speed="1.5"
Caustics speed
--------------
Float on the relative speed of any caustics objects in this level. Default 1.0.
2.0 = double speed, 0.5 = half speed, etc.
Example: caustics-speed="1.5"
Fog
---
The density tag was removed (it was unused anyway).
The max, height start, and height end tags were added.
fog-max: float capping the amount of fog to apply, default 1.0.
fog-start-height: minimum height of fog, default 0.0.
fog-end-height: maximum height of fog, default 100.0.
The fog scales smoothly according to both the height, and the distance from
camera.

New pipeline overview
=====================
Organized by RTTs
-----------------
To color:
- initialize the glow representations (no rendering yet)
- render the 3d skybox, if any (includes the usual skybox)
To the MRT (color, normals, depth):
- solids
To quarter1:
- glowmap
To various shadow maps:
- shadows
To tmp1:
- lights
To color:
- lights from tmp1 are multiplicatively blended
- skybox if there is no 3d skybox
- lens flare/god rays occlusion query (no rendering)
- solid post-processing
- transparents
To displace:
- displacing nodes, if any
To the screen:
- the post-processing chain
- GUI
Organized by passes
-------------------
Init: glow init -> 3d skybox
Main: solids -> glows -> shadows -> lights -> occlusion query -> solid PP
Transparent: transparents -> displacing -> PP
GUI: gui
