Thanks Kilon for your nice words. Currently, AstroCloud is a bit slow. For example, loading this image takes much more than it should. For now, speed is not our priority. AstroCloud has to be fast and we will make it fast. Probably relying on external library is the way to go.

Just to give a bit more context about why we are doing AstroCloud. ALMA is the largest observatory on Earth, making it the largest astronomical project in existence (http://www.almaobservatory.org). This is what humanity has best to detect life outside Earth. ALMA is made of 66 high-precision antenas making it possible to see deep in the universe. Unfortunately, there is no good software to process these immensely complex pictures. Some tool suite naturally exist, but they were not made for ALMA, making these existing tools largely suboptimal to process complex picture of ALMA. Faviola’s dream (and mine) is to produce a tool ready to be consumed by astronomers to process ALMA pictures. Faviola and I are currently seeking for additional resources on making this happen.

Regarding your help about documenting Roassal. It is very welcome! In one of my previous post, I said that 2014 will be the year of documenting Roassal. A book is on its way. We will need people to review it. So thanks!

Kind regards, Alexandre

Well then my hat off to you sir

I am asking because rendering graphics is certainly an expensive (CPU and RAM) process. Rendering graphics is certainly something that interests me.

Of course I dont expect Pharo to compete with C , but then thats why we have Nativeboost. But I would love to see Roassal evolve to a full blown graphics engine. Certainly motivates me more to learn Roassal as deeply as I can. I remember when you first said I should use Roassal for my vector editor , I was quite sceptical. But seeing all these new apps pop up from real scientists made me think twice and now I have put my vector editor on hold to learn more about Pharo and Roassal and of course Moose.

Would love to help you document it further. Though for now I am learning it in a very slow pace. Congrats to you and all people involved with the libraries and of course to the people making the apps. You certainly changed my mind and I would love to see more apps that show the potential of these libraries.

I am also wondering if you are so ambitious whether porting C libraries like imagmagick would make sense for Roassal.

Or possibly other C graphics libraries.

beautiful, I am a huge fan of astronomy and sci fi. Is the image of the galaxy rendered with Roassal or is it just an image file that Roassal is displaying ?

We’ve just added a new post that contains nice screenshots and (short) explanation about galaxies.

Faviola is doing a truly fantastic work.
