O dear god yes!

Ok, so in one of my graduate classes, a few students and myself got together and made this app:

One person hosts their webcam and everyone connects to it and is able to draw on layers that are on top of the livecam (everyone sees real time updates). Nothing extra ordinary, we wrote it in a class session, but hell some of the slides coming from this are hilarious! Damnit, we needed to make a screenshot key!

Oh god yes, and we have a few artists. Professor became a polar bear!

Also strangely enough, was turning into an amazing note taking app!

I am very interested in this topic as I have attempted such an app on my own in the past.

What language did you write it in?

I have worked with webcams successfully, but a drawing layer escapes me...

written in c++ .net. we ported the webcam capture to straight up images. Drawing layer is a toolset that interacts with a liquid (lls) layer of pixels (think grid of pixels), tool set just manipulates cells. Output mearly adds the layers together to get the aggregate. Also flatten user actions before transferring to simplify the undo button. The transfer of the content is done via a special strew of the torrent protocol thats specifically for images (or rather grids of pixels).

Really funny, when something funny is drawn, half the class starts laughing (ones that have the app), the rest of the class that does not know whats going on or is not looking over shoulders joins in not to be left out. Leaving the professor like "wtf"

It looked like English.....sounded like it too......but what the Hell did you just say?

Bunni just techno-dusted the room.

I understood everything upto C++ after that it was all gibberish.

All I understood was polar bear. Lost me after that.

Neato!

Reminds me of the Simpsons dvds I have. There is a special feature where a lot the artists talk about the episode as it's playing and all draw on the screen as it's playing too. It's cool to see what lines the artists use to draw the different characters or how their techniques differ...

what scares me is that my eyes no longer glaze over when he starts talking, sure he's way beyond me but i at least kinda get whats going on and just recognize that i still need to learn a lot.

which would be easier if my C++ teacher spent less time looking confused and more time knowing what the fuck she's teaching.

Jeez lol, you guys think thats bad you should here me going on about knowledge based systems and adaptive systems. Where you have entity based relationships that are produced from the relevant systems interpretations of a dataset.

Jonas, id recommend (if your just learning the concept of programing) to start with visual basic .net. Rather fucking stupid how universities introduce students to programing though to such a non novice friendly language. Would be like having a circuits 101 class that uses its entire semesters case study of some quantum chip (ok, im not a engineering major so those who are will have to help provide a better example). You have got to start simple, learn programing through a language thats closer to english. IMPO, vb is the closest and has excellent debuggers.

Our comp sci educational system needs readdressing. They are stuck on curriculum that are heavily out dated.... next they will force you to learn *shivers* java *gurgles mouth wash*

GO vb -> C# -> c++, or skip c#. Learning to program is much like learning another language. It takes years of practice to get the concept fully nailed, once you get there, youll be able to pickup new languages very, very, easily.

fuck java...
