I recommend that you start with the freeware version and read the user manual. Then, later you can buy a Shadows Pro version. The user manual will help you understand sundials and their construction.

L'heure moyenne indiquée correspond à une certaine heure solaire qui est celle montrée par l'ombre. L'ombre est toujours en heure solaire locale, c'est juste le tracé des lignes et/ou l'interprétation qui change et qui permet d'avoir l'heure moyenne. L'heure moyenne, corrigée de la longitude est effectivement l'heure de la montre (à l'heure d'été près)

It also includes an accurate explanation of the fact that the design is based on the stereographic projection, a key idea in make the astrolabe a possible device to manufacture by the standards of the time, as it meant that it relied only on constructing straight lines and circles.

Thank you very much Luis. Do not hesitate to spread the word around you and bring new users to Shadows Pro. 🙂

Ancient Indian Rishi

@@goldenmishra3148 It’s not known They say a lot of diferente people created it But I can’t see any human figuring out the workings It’s. Of divine origin That knows the Heaven’s Well . Maybe from a fallen Angel or not You will definitely find out on your judgment day . I can hardly wait. What a wonderful day

@@moontemple3027 Dont know who made the first astrolobe! That gave the knowledge of a simple divice to make once you know how Its sed it has close to a1000 uses But they are not all difined. Most things are easily understude when. You have some one that knows to show you

​@@goldenmishra3148 Indians discovered and invented everything yeah

@@goldenmishra3148 - Your blind arrogance and pride bears no bounds....

You have the credit at the last slide. It is Klaus Schulze.

@@francoisblateyron Oh! well Thank You good Sir, for the help. I never heard such music, it's so... catchy.

Yes, the shadow will always follow a straight line at the equinox regardless of the location, but the distance of the line from the style will vary.

@@francoisblateyron elle est droite seulement le jour de l'equinoxe ? Ou pendant toute la saison de printemps ?

@@lesbrebisperdues Juste le jour de l'équinoxe. En pratique on ne voit pas de différences quelques jours avant et après.

The 3D display is for sundials made within Shadows. You can export them to OBJ format to further process them in another software, but you cannot import 3D models from outside.

Thanks. A vertical declining sundial will be perfect, with its interesting line network. You can easily simulate it in Shadows (even the free version).

It's a projection of the sphere on a plane, so it's like seeing the sphere from outside, not inside.

En tout cas vous savez maintenant quel logiciel utiliser pour le tracé de l'astrolabe. Il vous restera la découpe et la gravure. ;-)

@@francoisblateyron j'aimerai beaucoup utiliser ce logiciel mais il me semble qu'il n'est dispo que pour windows ? Je travaille uniquement sur mac. 🤔

@@bricovintagerestaurations Oui mais pas mal d'utilisateurs sont sur Mac avec Wine ou Parallel.

@@francoisblateyron merci pour l'info !

The astrolabe was created way before the Renaissance. However, it spread across Europe during the Renaissance.

Al-ʻIjliyyah bint al-ʻIjliyy.

Some said it was invented/created by a woman but that theory was debunked.....or was it?

@@shadowspro-sundials Which country was the first to create this device?

@@dannwan8537 Difficult to say but probably around the eastern part of Mediterranean see.

From recent studies, blaming alghazali is quite simplistic view The main reason of stagnants in muslim academia is due to reducing to non-arabic ruler patronizing knowledge The ottoman rules were pretty much militaristic and did not promote knowledge as the previous arab rulers like in spain Seljuks whom are turk themselves while not focus in knowledge gives much leeway to the persian in governance, hence the knowledge culture spread... Until the mongol comes Researching of knowledges costs tons of money, such golden age can only happen when the ruler is die-hard fan of ancient knowledge like the caliph in baghdad and amir in andalus

With portuguese and spain capturing every muslim ports in india and southeast asia, the flow of money and trades to egypt(the last center of muslim academics) dwindles. It weaken egypt economically and was captured by ottoman. The age of exploration add more salts to the wound of mongol invasion towards muslim economically. So yeah, more money means more knowledge There's reason why renaissance starts in italy where venice and genoese control the spice trades to europe

You had me until the last idiotic statement.

Says the guy calling out a Text-To-Speech computer voice on Arabic/Greek pronounciation...

@@saintbrush4398 As it happens, I do read Arabic and Greek. I did my Greek and Latin at my school. As Science students at the University, we were required to take two, non credit, Non Science subjects. I chose Arabic / Hebrew and Comparative Religions. My parents were Atheists. I am a Non Believer.

"al aster laab" ? I`ve watched quite a few videos on this instrument now from many different sources of nationality and no one has ever mispronounced it the way you think it should be said. There`s an "e" on the end of the word. I can`t be bothered explaining it now but if you`re going to accuse someone of bad education, make sure you know what the fcuk you are talking about first. I don`t, but it doesn`t matter.....because I too am a non believer.....especially in human beings!

That might be the Arabic name for the instrument but in English it has been called an Astrolabe since 1390. Academic consensus is the instrument is almost universally known as a "star-taker" in whatever language you prefer, deriving that from the Greek name used by the originators of the instrument, that you quoted yourself, which is romanized to 'astrolábos'.

@@saintbrush4398 That's instant karma for my listening.

Avez vous réussi ?

@@skynet5305 réponse légerement en diféré (mdr) : Donc, oui! (enfin plus ou moins, ç'est assez réussis je pense, mais j'ai pas mal simplifié "l'araignée"....)

@@DonErikos ^^C'est le bon coté de youtube votre réponse décalé dans le temps, merci et bravo !

There is no English version yet, but I am planning to add subtitles soon, and later to create a similar video in English. In the meantime, you can get information in English on www.shadowspro.com. Thanks.

An English version is available on ruclips.net/video/NjdyMVDhfOU/видео.html

C'est un point de vue... ;-) Une autre vidéo plus détaillée et sans la voix électronique est disponible là : ruclips.net/video/ebUJDkvuO34/видео.html
