Solar Enthusiasts: Scripts to enjoy a "3D solar movie"

[rudi]

Hi.

You are a solar enthusiast?

for my personal fun I wrote these two scripts.

• The first one is downloading all the JPG solar pictures, starting at a given date.
• the 2nd one will display them in an Autoit GUI, with an adjustable image difference for your right and left eye:

"Stare through" your monitor, so that your left eye will focus the left image, your right eye the right image, then you will recognize the 3D effect.

 

If you have difficulties to "match" the left / right image to your left / right eye, then ...

1. decrease the GUI's size (PAGE-DN), until the "image-middle-distance" is a bit BELOW your eye's distance (depends on your monitor's size and your physiognomy)
2. put your face very close to your monitor, then slowly fade back, until you will recognize to see virtually THREE images
3. Wait a moment to recognize the 3D effect of the "middle image"
4. Concentrate on this "middle image" and it's 3D effect
5. AVOID rotating or moving your head in any direction, except forward/backward! This propably will kill down the focus, if you've had difficulties to get it in the beginning!
6. Try to SLOWLY fade back with your face even more, until you have reached a comfortable distance.
7. Now use PAGE-UP, do increase the GUI's (the images) size: Once you've caught the 3D "match", you can usually increase the size to values, you would have never ever been able to "match" at the first time. (The downloaded images are 1024 x 1024 pixels)

    author: Rudi Thilo +49 171 685 9 685
    Download the solar JPG pictures of NASA from the subfolders of the URL specified as first variable declaration
    
    1.) download the JPGs using this script
    2.) Use "Solar-GUI-2.au3 to display them as a movie inside an Autoit3 GUI as a "poor-man's-3D-cinema"
    Both scripts have to be in the same folder.
    have fun! :D

#cs
    autoit v3.3.12.0
    display the previously downloaded solar images as a movie in one Autoit3 GUI, to get some 3D impression
    use ARROW-UP to increase the GUI's size
    use ARROW-DOWN to decrease the GUI's size
    use LEFT-ARROW to run the movie backward
    use RIGHT-ARROW to run the movie forward
    use PAGEUP to increase the delta between the two images (more 3D effect)
    use PAGEDN to decrease the delta between the two images. Negative values will give you a strange effect
    use ESC to close the program

    have fun! :D
