Two separate issues...
First, the wiki documentation on Customizing Landscapes under the Polygonal Line Method states, "The landscape.ini file for a polygonal type landscape looks like this (this example is based on the Geneve landscape which was borrowed from Cartes du Ciel and comes with Stellarium): " I see no "Geneve" choice in my version (freshly downloaded 12.4,) and the PDF user guide makes no mention of a 'polygonal' choice.
Second, when I tried creating my own according to the directions, the program log states, "Unknown landscape type 'polygonal'" then goes on to say it expected a fisheye projection.
So, was this something that's been taken out (and if so, grr, as I really don't want to go through the trouble of trying to make a picture landscape,) or is this something yet coming? Or was somebody smoking something?
You seem to have CSS turned off.
Please don't fill out this field.
this type of landscape. introduced. into version. 0.13.0
That explains it, thank you for the explanation! :) My problem is not just not wanting to take time, it is also that I am in a box of buildings and have a sheer North face and large East face and don't have a camera that can handle that large a field. My lowest elevation is about 20 degrees, highest is somewhere between 70 and 85 for a long stretch.
So last night, figuring that may be the answer, I still managed to do what I needed thus:
1) Take the Moon png file, save a copy to new directory in landscapes folder. Do same with the landscape.ini file.
2) Resize the png canvas to 720 * 180, and save a copy. (Used FastStone for that, know it can be done in GIMP.)
3) In GIMP, delete the existing picture.
4) Draw a line from 0,90 to 720,90, using a color for the terminator - I chose dull light brown/orange.
5) Anything below pixel 90 is ground. Color appropriately with fill tool - I took a dark blue, deeper than Navy.
6) Draw lines above pixel 90 representing my horizon angles, vertical is elevation degree, horizontal is azimuth times two (i.e. bearing 060 becomes X 120, bearing 185 becomes X 370, etc.)
7) Use the bucket fill to paint the interior of the horizon wireframe with appropriate color. I chose a forest greeny color.
8) Export the file from GIMP back to a .png in the landscape directory
9) Edit the landscape.ini file using the Wiki parameters, my parameter file is:
name = darren
type = spherical
author = Darren Erickson
description = Horizon lines describing observing location from Darren's porch.
maptex = darren4.png
maptex_top = 90
maptex_bottom = 0
maptex_fog_top = 10
angle_rotatez = -89.1
polygonal_horizon_list = darren1.txt
polygonal_horizon_list_mode = azDeg_altDeg
polygonal_angle_rotatez = 0
minimal_brightness = 0.0075
9A) I had a horizon list because of what I was doing, so I included that as a file.
10) Fire up Stellarium and change landscape. Note any problems, repeat steps 6-9 as necessary.
I expect to tweak my "picture" proper a bit more, maybe even add textures.... But it works very well! :)
Thanks to you and all the devs - it's such a beautiful tool to use. Been using it for years even though I finally got my first telescope this last Christmas.
