Oldes 14-May-2009 [14190] | the question is when:-/ |
Steeve 14-May-2009 [14191x2] | Oldes i used XOR operator on black and white images of letters to extract the contours |
i can extract the contours with the graphic engine too, but then it's polluted with smouth corrections. | |
BrianH 14-May-2009 [14193x2] | Steeve, did you catch where Carl said that those features would be better added as native functions, than as misdefined operators? |
Never mind, that was already mentioned :) | |
Steeve 14-May-2009 [14195] | For my revenge i posted a puzzle |
BrianH 14-May-2009 [14196] | Geez, who is Meijeru ? I like Meijeru, someone who makes bug reports that we can fix or dismiss. Even the dismissed tickets serve as documentation. Thanks for commenting on some of those, Steeve - you put it better than I could. Meijeru reminds me of Steeve, circa 3 months ago :) |
Maxim 14-May-2009 [14197] | hehehe |
Pekr 14-May-2009 [14198] | BrianH: it is a strange situation - we are giving up on some "polymorphism", and replacing it with more functions to get the same reflectivity. No more first, second, third, etc. working on multiply types, but instead using values-of, words-of, etc. |
Maxim 14-May-2009 [14199] | the best testers are always those that don't know what they are doing. |
Pekr 14-May-2009 [14200] | I don't understand, why XOR and OR should be removed from functioning upon image datatype? |
BrianH 14-May-2009 [14201x2] | We got a lot of port! bugs fixed - and tickets usefully documented through their dismissal - thanks to Steeve. |
Polymorphism only makes sense when the concepts correspond. What we are removing is false polymorphism. | |
Pekr 14-May-2009 [14203] | Brian, Steeve mentioned that not all of vector bugs are fixed, is that correct? It would be probably good to fix them, no? :-) (well, if vectors have any role in new rebin/plugin/dll interface) |
Steeve 14-May-2009 [14204] | To be honest it's not frankly bugs but wishs |
BrianH 14-May-2009 [14205] | All of the vector bugs that were reported before the great vector rewrite are fixed. The new stuff, not yet. |
Steeve 14-May-2009 [14206] | like scalar math operations on vectors |
BrianH 14-May-2009 [14207] | There's a bug too, with mold of vectors. |
Maxim 14-May-2009 [14208] | are there any matrix operations for vectors? |
Steeve 14-May-2009 [14209] | in your dreams Maxim, only in your dreams... |
BrianH 14-May-2009 [14210x2] | Not yet. We're waiting to add that until we implement multidimensional vectors. |
Same with Steeve's scalar math request. | |
Pekr 14-May-2009 [14212x2] | multivectors? I am curious about its semantics ... |
I can't feel there is any intention to add such feature for 3.0 :-) | |
Steeve 14-May-2009 [14214] | can't or can ? |
Pekr 14-May-2009 [14215] | can't. It is not on R3.0 list of features, IIRC. |
BrianH 14-May-2009 [14216] | We aree also curious about the semantics of multidimensional vectors, which is why they aren't implemented yet. |
Steeve 14-May-2009 [14217] | I hope Brian may enter these features in Carl's brain, by force... |
Pekr 14-May-2009 [14218] | :-) |
Maxim 14-May-2009 [14219] | we need pekr to argue with carl too ;-) |
BrianH 14-May-2009 [14220] | They are lower priority than security issues (the reason for the new reflection), multitasking (the reason for the new system), etc. |
Pekr 14-May-2009 [14221x3] | I think that you have to use my past aproach - to cry loud, to cry often, to cry on many places ..... |
My experience is, that Carl works in his own world, and it is good, we communicate with him via some "API" :-) E.g. I had to mention article about the need to use better timers (not done yet) for something like 3 or 4 times. Then, when I found the right time and his mood to actually look into it, I think that he agreed that there is better solution than what we now have ... | |
Brian: I think that tasking is not going in for 3.0 | |
BrianH 14-May-2009 [14224] | What we then had, or what we now have? He redid timers once already... |
Pekr 14-May-2009 [14225] | I think that we need - plugins, security, gfx, gui, few protocols (later some engine like cheyenne inside), well, we need many things. Also current implementation of codecs is absolutly useless, no concept, just a workaround ... |
BrianH 14-May-2009 [14226] | We needed the system object changes for modularity and security too. Once we clean up for those, multitasking won't be that hard. |
Pekr 14-May-2009 [14227x2] | BrainH: I'll point you to one article, wait a min., I need to find it. Actually - it was Cyphre who found it IIRC. |
http://www.codeproject.com/KB/system/timers_intro.aspx we imo need multimedia timers, definitely. So "small" change can make big difference. We don't ned to look pre W2K imo. And it is crazy that MS has all this mess in their API. The good thing is, that timers are host layer, so community can advance it ... | |
Will 14-May-2009 [14229] | could this help in R3? http://www.cilk.com/The Cilk++ cross-platform solution offers the easiest, quickest, and most reliable way to maximize application performance on multicore processors. |
BrianH 14-May-2009 [14230x2] | The reason Carl is focusing on these simple datatype changes now (like vector!, image! and money!) is because they affect rebin, and rebin not being done is currently what is blocking the release of the host code. |
Will, that's not cross-platform enough for R3 :( | |
Pekr 14-May-2009 [14232] | I wonder how he resolved the problem he advised in R3 Chat, that with his initial idea not everything could be dynamic (draw). Hopefully he found some solution. |
Maxim 14-May-2009 [14233] | is R3 coded in C or C++ |
Pekr 14-May-2009 [14234] | Well, if Carl uses CureCode, I should post Timer related ticket probably :-) ... and maybe BlitJit/AsmJit ones too :-) |
BrianH 14-May-2009 [14235] | Mostly C, though AGG is written in C++. |
Pekr 14-May-2009 [14236x2] | Max - I think it is C, although AGG is C++ |
BrianH: what is FIRST+? What is the difference to pick port 1 or just first port? | |
BrianH 14-May-2009 [14238x2] | FIRST+ takes a word that refers to a series and it advances the word to the next position while returning the first value. |
It's a speed/simplicity thing. | |
