The implementation is proprietary and there is no source code available. I would just take the architecture/API as inspiration for an implementation in Smalltalk. Clutter (http://www.clutter-project.org/) and an uncountable number of Javascript libraries contain open-source implementation of such animation frameworks (LGPL though).

I was storing 64 bits: serialize: aFloat on: aWriteStream aWriteStream nextNumber: 4 put: (aFloat at: 1); nextNumber: 4 put: (aFloat at: 2). materializeFrom: aReadStream ^ (Float new: 2) at: 1 put: (aReadStream nextNumber: 4); at: 2 put: (aReadStream nextNumber: 4); yourself. that's why I see a difference! thanks!!!

I agree, but the above code does not have that problem. In fact it works pretty well, i.e. when the system is busy/slow it just sets the end state of the animation. > A good example for morphs animation is bouncing atoms. But i'm not > sure if it still residing in pharo images. Now if somebody is looking for an interesting project I would suggest to implement CoreAnimation clone (http://en.wikipedia.org/wiki/Core_Animation) CoreAnimation is a beautiful and powerful object-oriented animation system for Cocoa. It should be strait forward to port the API, because Cocoa is essentially a nice implementation of Morphic. Lukas -- Lukas Renggli www.lukas-renggli.ch

Re: [Pharo-project] FloatArray inaccuracy

by Igor Stasenko

Float numbers are inexact and always been. Maybe you meant that they are more inexact than you expected? :) FloatArray stores floats using 32-bit floating point precision format. While Float(s) using 64 bits. No surprise that values stored in FloatArray are less precise.

Because if you do it otherwise (like in a loop), then you pausing a rest of processing, blocking UI etc and this is not good. A good example for morphs animation is bouncing atoms.
