[Pharo-project] The video about Athens
Hello, all I recorded a small introductory video about Athens. Here it is: http://vimeo.com/40653315 (about 21 minutes). I explain some basic stuff like drawing things using Athens canvas, building paths, use of transformation matrices etc. Please note, this is a first video i ever recorded in such context in my life, so don't be too harsh :) Also, note that the animations are jagged because of video recording frame rate, not because it is that slow in reality. There are still a blog post pending about it.. which i plan to finish when i will finish ;) -- Best regards, Igor Stasenko.
Great! Dr. Geo will be a great client Hilaire Le 19/04/2012 16:41, Igor Stasenko a écrit :

Hi Igor,

no, it was taken from OpenVG package , which is ported from C sources. But i currently working on SVG importer for Athens.. and i using your code as a reference.

Oh yes... and if you notice sometimes i say "we" not "me" during video. Because i was not alone doing all the work. I'd like to thank a LOT to Fernando Olivero for his help and dedication with making Cairo backend for Athens!!! He were visiting our team during March for one month and we did a lot of things together, pushing Athens to much useful state. -- Best regards, Igor Stasenko.

No such luck here ; no sound whatsoever, in any version, downloaded or streamed.

Same for me... no sound :-(
It's so great stuff!!! :)) Is cairo used as athens backend for this demo? Is it should work with Bitblt backend? In demo I see many usage of angel parameter for transformations. Do you think about "angel unit objects" like "90 degrees" or "2 radians" instead of raw numbers ? How #scaledBy: works with Point argument (self extend) and Float like (frame / 100 sin abs) at the same time? What' logic? Best regards, Denis 2012/4/19 Igor Stasenko <siguctua@gmail.com>

sudo port install cairo +universal universal is important, so it builds 32-bit binary. if you just do without it, it will buuild 64-bit library version, without chance to be used by Cog VM. On 20 April 2012 00:09, Sean P. DeNigris <sean@clipperadams.com> wrote:

there are two methods - rotateByRadians: and rotateByDegrees: It makes things more explicit, while if i just have rotate: or rotateBy:, then it will be a bit ambiguous, whether argument angle is in radians or degrees (different frameworks assuming different things to be default)
How #scaledBy: works with Point argument (self extend) and Float like (frame / 100 sin abs) at the same time? What' logic?
for uniform scale, you provide a sole number, and for non-uniform - a point, with x and y scale factors separately. There is a scaleX:Y: method, while scaleBy: is more for convenience.

+1 for the descriptive names. Too often I see strange contractions that aren't immediately obvious, and or otherwise inconsistent naming (not just in Smalltalk), and it ruins the illusion of having a consistent whole :). It bugs me a little ;). It would be really cool if we could agree as a community to follow a well-defined naming scheme. I'm rather fond of this book â Smalltalk With Style Any thoughts?

ah, yes.. that might be the problem. i recorded with defaults on, which records mic input and audio input. but since there is no any audio during record , only my voice on mic, it is silent and useless. i will try to recode the video next week with help of Marcus.

Looks great. I just tried to give it a try, but I get stuck. I did the following on Mac Lion: - I took Pharo 1.4: http://gforge.inria.fr/frs/download.php/30620/Pharo-1.4-14438.zip - I ran it with CogNB: https://ci.lille.inria.fr/pharo/view/NativeBoost/job/NB-Cog-Mac-Cocoa/lastSu... - I then executed: Gofer new squeaksource: 'Athens'; package: 'ConfigurationOfAthens'; load. ((Smalltalk at: #ConfigurationOfAthens) project version: '1.0') load. - Then: AthensDemoMorph new openInWorld But I get "Error: function unavailable" for: - #(#AthensCairoSurface #cairo_image_surface_create #(#int #aFormat #, #int #aWidth #, #int #aHeight)) - '/opt/local/lib/libcairo.2.dylib' See the attached log. I guess I am missing the cairo library. What should I do to get it? Cheers, Doru On 19 Apr 2012, at 16:41, Igor Stasenko wrote:
Hello, all
I recorded a small introductory video about Athens. Here it is:
(about 21 minutes).
I explain some basic stuff like drawing things using Athens canvas, building paths, use of transformation matrices etc.
Please note, this is a first video i ever recorded in such context in my life, so don't be too harsh :) Also, note that the animations are jagged because of video recording frame rate, not because it is that slow in reality.
There are still a blog post pending about it.. which i plan to finish when i will finish ;)

Hi, on 64bit Fedora with "cairo.i686" installed the right library path is /usr/lib/libcairo.so.2 -- Pavel On Thu, Apr 19, 2012 at 4:41 PM, Igor Stasenko <siguctua@gmail.com> wrote:
