Sorry for the noise in mc_id.h, but somebody decided they want DOS
line endings and I couldn't allow that to happen. When not doing that
put the whole thing into diff, I decided to just fix the indentation
too while I was at it.
Needed bugfixing of some overlooked unsigned char usages for block IDs,
as otherwise the lighting would be scuffed.
Concerns issue #1486.
Many things work, some don't. Notably, genPOI doesn't work, and
there's some signedness comparison stuff going on in the C extension.
This also completely drops support for Python 2, as maintaining a C
extension for both Python 2 and 3 is a pain and not worth it for the
9 months that Python 2 is still going to be supported upstream.
The documentation needs to be adjusted as well.
All of the few tests we have pass, and rendering a map works, both
with a configuration file and without. We can also use optimizeimages.
Concerns #1528.
Some bad distributions (Debian) apparently are not good enough to
have a Pillow version from this decade packaged.
Therefore, we need to do it the painful way of prefixing our
symbols and refactoring everything to use them.
A new header file called "utils.h" has been added for this purpose,
and it is included in "overviewer.h".
The following macros have been prefixed with "OV_":
- MIN
- MAX
- CLAMP
- BLEND
- MULDIV255
Additionally, the C extension version was bumped to 56 because 55
was reverted back to 54.
temp/humnidity was calculated so it matched the pixel at the start of each biome
as shown in the color template (http://minecraft.gamepedia.com/File:Biomes1.7.2.png)
TODO: switch to using coordinates in the image instead of temp/humidity
Inlining the function allows the compiler to optimize away the
function completely. Clang 3.7.1 does exactly that.
This leads to an error, if the library is used with python:
% ./overviewer.py
Traceback (most recent call last):
File "/tmp/minecraft/Minecraft-Overviewer/overviewer_core/__init__.py", line 20, in check_c_overviewer
import c_overviewer
ImportError: /tmp/minecraft/Minecraft-Overviewer/overviewer_core/c_overviewer.so: undefined symbol: estimate_blocklevel
Something has gone wrong importing the c_overviewer extension. Please
make sure it is up-to-date (clean and rebuild)
A usecase to demonstrate a possible application of the extended functionality:
**"Rails Overlay that draws only the rails that are on Cobblestone for a subway map."**
With this patch it is very easy to achive that:
```python
MineralOverlay(minerals=[(((0, 0, 0, 66), (0, -1, 0, 4)), (255, 0, 0, 255)),
(((0, 0, 0, 27), (0, -1, 0, 4)), (0, 255, 0, 255))])
```
In this case the overlay will be red for rails on cobblestone and green for powerrails on cobblestone.
The syntax is `(<tuple of conditions>, <target color>)`
* where `<target color>` is a 4 tuple with a `(r, g, b, a)` color
* and `<tuple of conditions>` is a tuple with an arbitrary number of conditions with the following syntax:
`((relx, rely, relz, blkid), ...)` where the `rel<>` parameters specify the relative coordinates to the block that is checked if it matches bklid.
In the example the fist tuple `(0,0,0,66)` checks if at the current position is a
rail while `(0,-1,0,4)` checks if at one below the current position is a cobblestone.
If both are true then the color `(255, 0, 0, 255)` is used.
A Sample Config file exploiting the capabilities:
``` python
worlds['My World'] = "~/.minecraft/saves/test/"
outputdir = "/tmp/test_render"
rendermode = "lighting"
renders["render1"] = {
'world': 'My World',
'title': 'A regular render',
}
renders["render_overlay_dafault_rails"] = {
'world': 'My World',
'title': 'Default Rails',
'rendermode': [ClearBase(), StructureOverlay()],
'overlay': ['render1'],
}
renders["render_overlay_cust_rails"] = {
'world': 'My World',
'title': 'Custom Rails',
#relative coordinates [[(relx, rely, relz, mineral)], (red, green, blue, alpha)]
'rendermode': [ClearBase(), StructureOverlay(structures=[(((0, 0, 0, 66), (0, -1, 0, 4)), (255, 0, 0, 255)),
(((0, 0, 0, 27), (0, -1, 0, 4)), (0, 255, 0, 255))])],
'overlay': ['render1'],
}
```
The "Default Rails" overlay uses default coloring of the structures overlay. "Custom Rails" uses some custom coloring.

is_transparent returns 1 for every unknown block because that's an easy way to
make them ignore lighting, however, this makes cave render useless with a map
containing unknown ores.
The definition is_known_transparent checks whether a block is transparent and is known.
This is a workaround, a proper fix would be to have unknown blocks be neither transparent nor
solid. Or make them both. But don't prefer one of the two.
The new nether quartz ore block was not recognized and was causing "pillars"
of netherrock to be rendered (with a quartz ore on top). the same
seemed to be happened with Lava, so included taht as well
Fix for Ender Portal Frame, w/eye of ender, in all orientations
Minor fix for Comparator back torches
Update to lighting on Quartz stairs
Added Quartz Half Slabs
The nether rendering mode was not properly handling x and z values
outside of the range 0 to 15. This was causing an out-of-bounds
segfault when accessing the remove_block array.
