[Pharo-project] Status of Rome?
Hello guys, i seen there are some recent activity with Rome in Pharo, but i found that things are now scattered over a different repositories, and its hard to find out, what version is latest and which one i could use. I found that the latest things is in a SqS/PharoTaskForces/Rome, which is a merge of all Rome-XXX packages into a single one. Is this most recent thing you are working on? Actually, all i need is just a reference canvas, but it would be cool if i could run some working code & examples. :) -- Best regards, Igor Stasenko AKA sig.
in Athens in squeaksource. We will flush all the other repositories and only keep this one. We will put the old files probably there too. Why that? Because the code was full of half done class, broken methods.... Tweak copied and pasted code from Squeak Stef On May 22, 2010, at 7:29 AM, Igor Stasenko wrote:

Yes, it requires some cleanup/reorganization. So, SqS/Athens is the latest & current state of art?

somehow yes. Cyrille is working on it and he showed me some results using or not the rome pluging On May 22, 2010, at 10:50 AM, Igor Stasenko wrote:

Good. I am now trying to implement a vector(truetype) font rendering. Just finished a little GPU fragment shader snippet, which renders a quad bezier curve, with antialiasing included :) You supplying 3 points, which defines a quadratic curve to GPU, and it does the rest. This is a basis for smooth true-type font rendering, since it contains a contours consisting from line segments or quadratic bezier segments. -- Best regards, Igor Stasenko AKA sig.
That looks cool. I am looking forward seeing that stuff in action :-) Lukas 2010/5/22 Igor Stasenko <siguctua@gmail.com>:

Err.. what you mean by pharo? I making a calls to OpenGL, using NativeBoost's OpenGL bindings. All stuff is coded in smalltalk, so sure thing its does things in pharo :)

Well I was wondering if you were doing the same as juan.... Juan showed me better rendering written in SMalltalk code than calling openGL/cairo... for antialiasing so I'm eager to see morphic30

well, you can do sophisticated AA by implementing shader programs. It will run on GPU, means veeeery fast. And if you would ask me, what i prefer - quality or speed, i will definitely take speed. Because, when you need to render thousands of glyphs on a screen (which is a usual scenario for text-based editors/viewers), you have to sacrifice the quality anyways. Otherwise, wait for next 10 years till hardware will be able to render it withot crawling like a hog. Actually, i would like to cooperate with Juan about this. I think that AA techniques (as well as many others), could be moved to GPU, freeing CPU from this time consuming task.

I think that this is indeed good to have something. Now if we have both then even better

Using the TTFontReader? Iirc, that parses the contour data, even an example of rendering it with ballon drawBezier.... somewhere :) Cheers, Henry Den 22. mai 2010 kl. 17.42 skrev Igor Stasenko <siguctua@gmail.com>:

Yes, i will use this data directly, in same way as balloon does, and it will be rasterized by GPU.
