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 making a calls to OpenGL, using NativeBoost's OpenGL bindings. >> All stuff is coded in smalltalk, so sure thing its does things in pharo :) >> >>> >>> On May 22, 2010, at 4:54 PM, Lukas Renggli wrote: >>> >>>> That looks cool.

Re: [Pharo-project] [squeak-dev] Re: Cross-fork Metacello configurations

by Bernhard Pieber

Dear Squeakers, I agree with Sean that the necessity to copy a configuration class from a cross-fork package ConfigurationOf... to the proposed Configuration package for Squeak makes life much more complicated and more work for those good fellows who care to create portable packages. IMHO that is a bad things for all forks. The ability to support cross-fork development is one of the greatest assets of Metacello. I see no reason not to use it. The good news is that - as Sean already wrote - all the good things of Andreas proposal could work equally well even if we reused the cross-fork ConfigurationOf... packages. The fact that some core developer copies such a package to the trunk could mean it was tested with Squeak. The only difference would be having more packages in the Monticello Browser. (They could be hidden from there.) IIUC one thing misses from Metacello right now to use it in the way Andreas envisions: A categorization for an installer UI like Andreas' ConfigBrowser. I am sure Dale could be convinced to add that to the metadata/API if cross-development configurations could continue to be supported. Did I miss something? Just my 2 cents.

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.
