Nightshade Legacy

Rendering of image as panorama

Asked by John Cotton

Is it possible to produce a panorama with Nightshade? I tried the following little script

# Pan test script
flag script_gui_debug on
clear
image action load filename spirit2.png name pan coordinate_system dome azimuth 0 altitude 0 scale 360
image name pan alpha 1 rotation 0

wait duration 20

image name pan action drop

script action end

using a 4096x512 Mars pan image. The result is strange - the image starts at full height in N
then tapers to 0 height in E and W. It builds back to full height in S, but that part of the image is
upside-down.

Is it possible to produce a pan with STS??

John,

My recomendations:
- Use the command "landscape", it is created specifically for panos
- With "landscape" you don't need to use "wait duration", the pano will be there including after finish the script.
- Use a pano image 4096 x 2048 or 2048 x 1024, or 1024 x 512, so with relation 2:1 (you can fill transparent)

NightShade support 3 types of textures for landscape: "old_style", "fisheye" and "spherical". Your pano looks like a "spherical"

If so the pano will be charged:

landscape texture spirit2.png action load type spherical

If you need to orient the pano, include rotate_z X, with X the degrees you want to rotate the pano. By default, the left-border of the pano is facing to the East.
