--heightmap: generate the height map, in colors
--heightmap-grey: use shades of grey instead of colors
--sealevel <n>: define the sea level (below sea level is drawn in blue)
--heightmap-scale <f>: scale the heights by f (for the purpose of
color selection)
When generating a heightmap, a special colors file is needed,
that defines just the blocks that should be considered part
of the ground. That means that normally, any plants, special
nodes and water should not be included.
The option --tiles has two new possible values: 'block' and 'chunk'
'block' creates tiles corresponding to map blocks
'chunk' creates tiles corresponding to map chunks
(chunks are the unit of map generation).
An option --chunksize was added to manually override the chunk size.
Note: on the y-axis scale, the block coordinates are rendered above
the line, instead of under the node coordinate, as that makes
them adjacent to the block they refer to.
for illustration: create a map with --drawscale --tiles=16 --tileorigin=world.
this makes the tiles correspond to the map blocks.
Consider a point with y-coordinate 64. It is part of a map-block with y=64..79.
This block is located at and above the line corresponding to y=64. On the y-axis,
it is therefore most intuitive to render the block coordinate above the line.
As the best color for water depends on the rendering parameters
(i.e. the --drawalpha mode: none, average or cumulative), two
additional colors files are provided for these alternatives.
This new mode averages the colors of all transparent blocks, instead of
making the colors progressively darker and more opaque.
This 'average' mode is now the default when using --drawalpha. It can be
explicitly selected using --drawalpha=average. The old modes can be selected
using --drawalpha=cumulative[-darken].
It is recommended to change the colors of water as well. These are in a
separate patch.
As this comes with a significant performance penalty, this
feature must be enabled using the command-line option --drawair
For best results, the color of air should be fully transparent,
so that underlying nodes will override it.
This is useful to show invisible ('air' or 'invalid') nodes in blocks
that are in the database using a different color than blocks that are
not in the database (which will have no color at all, causing the
background color to show).
Minetestmapper can now be installed into a proper directory hierarchy
(instead of all files being dumped into /usr/local/. for instance.)
Non-hierarchical installation (or creation of a non-hierarchical archive)
is also still supported, and remains the default, for backwards compatibility.
Packaging on windows remains unchanged, due to lack of infrastructure :-)
A colors file can now specify other colors files, from which
additional node color specifications will be read. This allows, for
instance, using system-installed colors file for most colors,
and only overriding some of its colors in a custom colors file.
As a purpose of using a custom colors file may be to leave the colors
for some nodes undefined, it is now also possible to undefine a
previously defined node color (i.e. after reading another colors file
which defines a color for the node).
- Continue processing if libraries are not found (so that all missing
libraries are reported)
- Set compiler flags correctly if CMAKE_BUILD_TYPE is not set (fixes bug #0)
- Make CMAKE_BUILD_TYPE=Release the default
- Increase optimisation level for Release
