New World Map

[waldronate]

Putting in two stereographic endcaps (developed circa 0 AD) helps to offset the more modern Wagner VII (1949 AD) to make everything average out about 650AD. It works that way, right? If you want to do this, put the following text in your FT Projection.txt file to get that projection:

Projection 89, "Wagner Stereographic Endcaps"

Scale 1.0
Description "Wagner VII with Stereographic Endcaps"

Segment "Wagner VII", 0, 0, 0, 0, 1, 0, 0
scale 1, 1
Offset 0.0, 0.0
Effective -180, 90, 180, -90
Rotate 0
EndSegment

Segment "Stereographic", 90, 0, 0, 0, 1, 0, 0
scale 0.5, 0.5
Offset 0.0, +0.559
Effective -180, 90, 180, 60
Rotate 0
EndSegment

Segment "Stereographic", -90, 0, 0, 0, 1, 0, 0
scale 0.5, 0.5
Offset 0.0, -0.559
Effective -180, -60, 180, -90
Rotate 0
EndSegment

Now that is so COOL!

I can use the modern bit for accuracy and the old bit to suggest the style of presentation

Could also argue it looks good for SF settings too!


I love this site

Another projection you might want to consider is cubic.
I don't know if FT can generate it. I used MMPS and ImageMagick to create this example.

One advantage of cubic is that each of the sections is drawn as if you were looking straight down at it, so the shapes aren't distorted as much as in some of the other projections. There's also a lot of room for adding comments

Here's the Cygwin bash script I used. It has lots of room for improvement.

#! /usr/bin/sh -x
convert $1.jpg tmp.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat 0 -long  90 -w 512 -h 512 -f tmp.ppm >tmp_px.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat 0 -long 270 -w 512 -h 512 -f tmp.ppm >tmp_nx.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat  90 -long 0 -w 512 -h 512 -f tmp.ppm >tmp_py.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat -90 -long 0 -w 512 -h 512 -f tmp.ppm >tmp_ny.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat 0 -long   0 -w 512 -h 512 -f tmp.ppm >tmp_pz.ppm
../project gnomonic -grid  -gridcolor 255:255:255 \
  -scale 2 -lat 0 -long 180 -w 512 -h 512 -f tmp.ppm >tmp_nz.ppm
#
ppmmake black 512 512 >black.ppm
#
montage black.ppm  tmp_py.ppm black.ppm  black.ppm \
        tmp_nx.ppm tmp_pz.ppm tmp_px.ppm tmp_nz.ppm \
        black.ppm  tmp_ny.ppm black.ppm  black.ppm \
-mode Concatenate -tile 4x3 $1_cubic.jpg

p.s. you also could print it and cut it out to make a simple world. Of course, there are other projections which can be used to make a more spherical object if that's desirable.

Very resourceful Selden!

I like the cubic projection. I'd consider that if I get further from Fractal Terrains. Right now I'm just digging the idea that for a working game world map I can center on any place, set my scale, and print. I'm experimenting with a work flow as much as anything.

Interesting script! I've never used bash for that.
