It is the base (together with Fourier analysis) of most of the DSP (Digital Signal Processing) field. It is therefore the basis of digital audio and photography. But it seems I am the first one to apply it to 2d rendering! I have been working on this for the last 3 years, after finishing my Ms.Sc. in CS on Image and Signal Processing.

I am still changing the code a lot, but when it stabilizes I'll do a VM plugin. I guess it would be about 100 times faster. The other option is to use Igor's NativeBoost. That could perhaps be 10 times faster than the plugin, at the cost of portability and hand written asm (I'd done lots of asm in a previous life). > > Cheers, > Juan Vuletich > >> On 2 June 2010 13:43, Juan Vuletich <juan(a)jvuletich.org> wrote: >> >>> Hi Folks, >>> >>> I'm new to this list, but many of you already know me. >>> >>> Morphic 3 is a deep redesign of the Morphic framework.

Re: [Pharo-project] Can I use Projects in Pharo?

by Schwab,Wilhelm K

I think you are missing the OP's point. The goal (unless I am missing something) is to have a way to open say four browsers on specific classes and methods and maybe a workspace or two to work on one particular project/task, and to do the same for other tasks. All of this stuff would remain readily accessible with a high-level "table of contents" that allows on to enter a task, change something, and then switch to another task. My argument against this would be that it seems potentially memory hungry and perhaps sluggish due to all of the potentially invisible tools' updating themselves on various events, but if we ignore it in our images, we won't suffer much. I agree that doing this with separate images is a step backward.

Re: [Pharo-project] Can I use Projects in Pharo?

by Schwab,Wilhelm K

Projects as described might be similar to Dolphin's IdeaSpace. For whatever reason, I never liked them very much, so I am not the best person to comment. What I found most effective was to have filters on browsers so they would show me only subsets of the image and were easily launched from a tool that was always available in my image. That said, I can see why one might would want to have different tools open for different tasks, and be able to easily move between them. I am not sure about the objections to Squeak projects, other than IIRC, they use SmartReferenceStream, which I find to be horrible in various respects. The output is verbose, layout conversions do not anticipate the needs of an end user nor of the developer trying to protect the end user from a walkback, and the conversion methods go in the wrong place (attached to the serializer instead of the class that changed). In a word, YUK!!! Bill ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Sean P.
