Lighting Lighting
======== ========
Minecraft stores precomputed lighting information in the chunk files
themselves, so rendering shadows on the map is a simple matter of
interpreting this data, then adding a few extra steps to the render
process. These few extra steps may be found in
``rendermode-lighting.c`` or ``rendermode-smooth-lighting.c``,
depending on the exact method used.
Each chunk contains two lighting arrays, each of which contains one
value between 0 and 15 for each block. These two arrays are the
BlockLight array, containing light received from other blocks, and the
SkyLight array, containing light received from the sky. Storing these
two seperately makes it easier to switch between daytime and
nighttime. To turn these two values into one value between 0 and 1
representing how much light there is in a block, we use the following
equation (where l\ :sub:`b` and l\ :sub:`s` are the block light and
sky light values, respectively):
.. image:: lighting/light-eqn.png
:alt: c = 0.8^{15 - min(l_b, l_s)}
For night lighting, the sky light values are shifted down by 11 before
this lighting coefficient is calculated.
Each block of light data applies to all the block faces that touch
it. So, each solid block doesn't receive lighting from the block it's
in, but from the three blocks it touches above, to the left, and to
the right. For transparent blocks with potentially strange shapes,
lighting is approximated by using the local block lighting on the
entire image.
.. image:: lighting/lighting-process.png
:alt: The lighting process
For some blocks, notably half-steps and stairs, Minecraft doesn't
generate valid lighting data in the local block like it does for all
other transparent blocks. In these cases, the lighting data is
estimated by averaging data from nearby blocks. This is not an ideal
solution, but it produces acceptable results in almost all cases.
Smooth Lighting
---------------
In the smooth-lighting rendermode, solid blocks are lit per-vertex
instead of per-face. This is done by covering all three faces with a
quadralateral where each corner has a lighting value associated with
it. These lighting values are then smoothly interpolated across the
entire face.
To calculate these values on each corner, we look at lighting data in
the 8 blocks surrounding the corner, and ignore the 4 blocks behind
the face the corner belongs to. We then calculate the lighting
coefficient for all 4 remaining blocks as normal, and average them to
obtain the coefficient for the corner. This is repeated for all 4
corners on a given face, and for all visible faces.
.. image:: lighting/smooth-average.png
:alt: An example face and vertex, with the 4 light sources.
The `ambient occlusion`_ effect so strongly associated with smooth
lighting in-game is a side effect of this method. Since solid blocks
have both light values set to 0, the lighting coefficient is very
close to 0. For verticies in corners, at least 1 (or more) of the 4
averaged lighting values is therefore 0, dragging the average down,
and creating the "dark corners" effect.
