property "shader"

Peter Amstutz — 2008-08-19T01:29:31

Just got back from SIGGRAPH a couple days ago. This year's unofficial technical theme was "the year of general purpose computing on GPUs (GPGPUs)". This got me thinking about how the CPU controlling the GPU is like a server and client communicating over a network. Just like giving the user a high quality, low latency experience means moving computation to the client, getting better graphics performance means moving computation to the GPU. What is interesting is that the programming model for GPUs is relatively standardized, and is based on functional programming principals that avoid side effects (which is what makes massive parallelism possible.) They define transformations of some input data to some output data. So my idea is that in VOS, one could associate a property value with a "property shader" which defined a transformation of that data. This could include typical graphics functions (vertex shaders, fragment shaders) but also be applied further up the graphics pipeline, for example to interpolate the world position of a moving character based on the last know position and some time step, or render effects like speech bubbles. The latter case is interesting because it splits up the event into a semantic part (the text message being communicating) and a presentation part (the shader that draws it). The interesting thing about GPUs that I didn't realize until last week is that they have been abstracted behind a virtual machine model; this means moving shader programs around the network in source or bytecode form is realistic since it will be compiled to the native architecture on the fly. The upcoming OpenCL ("Open Compute Library" or "Open Computing Language") is interesting since it's an attempt to standardize the CPU/GPU interface backed by the Khronos group (the same people that maintain the OpenGL spec.) All that said, VOS is pretty far away from actually trying out these ideas, but I wanted to throw the idea out there.

Why not? :)

Do you know the language: http://www.iolanguage.com/ http://www.quag.geek.nz/io/getting-started/ It is very small and easily embeddable language. It is Object oriented but very simple. It has no classes, but only objects (same as JS). And instead of methods it has messages ( File.open() is actually "send message 'open(param)' to object File). All things there are objects - numbers, base library, key words - they are just ordinary objects. So why I mention it? Why not to build VOS on top of existing language implementation? :))) Instead of scripting bindings - you get whole language for scripting. Instead of recreating object environment - you just use existing one. Instead of hard way of creating all object in C++ you could use most of scripting language and implement base library objects in C/C++ and embed them as IO objects. This will help newcomers a lot - just write scripts to make content. http://www.quag.geek.nz/io/visual/ (could you draw something like this for VOS? ;) It will simplify thing alot. If you think that it is not possible in internet environment I will not agree. Simple example - if you try to reference non existing object that will not end you program. It will load that object from file instead and program just continues. Same way it could import remote object from external server or deliver a message to it (this part needs to be done :) ). Malx

Rough graphs of #vos channel activity

Reed Hedges — 2008-08-07T23:39:14

First two graphs, averages of number of users on the channel. Not a great gauge of activity or when the best time to be on the channel, since most of the activity on #vos is just lurking. Since there's a small number of users, we can look more closely at who is on when I think. I think charting that is beyond the capabilities of gnumeric though... will need to think about that. I'm tempted to just put some basic graphic features in my Qt UI prototype and write a function to load a text file into dummy vobjects for use in that UI... Reed

I have a new top priority project that must compete with VOS -- Zephan Isaac was born on Friday at 7:30 PM! Though so far he's been great and we're well rested (so far) and on top of the world. More photos and news will be on my web site and on flickr in the upcoming weeks. Reed

getting back on track

Peter Amstutz — 2008-07-03T02:57:22

I just wanted to mention that I have recently started taking the train to work instead of driving. This gives me about 45 minutes each way of reliable, uninterrupted time to do a bit of hacking, so I will finally be able to get back on track working on VOS after a couple months of coding drought. Since my laptop is a MacBook Pro, the first order of business will probably be to get the voss5 branch to work on OS X. The commuter rail also offers a 802.11 to cellular bridge so I even have Internet access! There are still some outstanding design issues I am mulling over, once I have resolved the immediate issues with my development environment, we'll have to restart the conversation on design and strategy.

Web Site

Reed Hedges — 2008-06-30T17:47:35

Am thinking of switching over to the new website I was working on earlier (http://interreality.org:4088), but without the half-assed background image. Would be nice to create a nicer one but don't have time. I'll also do an editing and clarity pass to try to improve whatever wording I can, and fix up the layout and Javascript issues. I do think I'm just going to dump everything to a Wiki, either the current Moin, or migrate to MediaWiki or something else. It was great to eat our own dogfood by using VOS for the website, and it triggered some useful features and fixies, but that S4 dogfood is pretty stale by now! If we get further along in S5 and reimplement hypervos or something hypervos-like using it we can move the site back into that (and having available what the wiki gives us will be a good features goal). I'll include the current wiki pages but not really link them to the main site except selectively, to avoid linking in too much confusing info... maybe have an "s4" category that collects all the potentially out of date info, and seperate out "ideas" from current info.

Irritated by wxwidgets

HEBLACK, J — 2008-06-05T19:28:05

Hey, I (Blackhesonja) put in a bug report about their (wxwidgets) wxbase-networking stuff. The wxbase networking-stuff did not work unless one line in their source-code was removed. After removing that one-line in their source code networking would work but I-felt that there were other bugs! This was the offending line: bool has_event_loop = wxTheApp->GetTraits() ? (wxTheApp->GetTraits()->GetSocketGUIFunctionsTable() ? true : false) : false; Has anyone here tried asio? Apparently it is really good since the C++ boost organization has accepted it into their libs. You can also use asio without the boost lib and join the asio mailing list since theres' only 300 or less on it right now. But you have to use the boost license or something like that. http://alexott.blogspot.com/2007/10/what-is-boostasio-and-why-we-should-use.html http://think-async.blogspot.com/ http://asio.sourceforge.net/ Since boost has accepted a cross-platform networking lib that makes me think why would they not accept a cross-platform 3d library or even a cross-platform 2d widget library? Why? "The letter you write today could change your tomorrow." (Blackhesonhj)

some work in designing entity-relation schemas

Reed Hedges — 2008-06-02T15:00:13

This is about schemas for describing data shared between applications, was developed as part of WinFS for Longhorn though this part of it wasn't eventually actually included in Vista. I think I can download the full paper if anyone wants it. http://portal.acm.org/citation.cfm?doid=1247480.1247532 Compiling mappings to bridge applications and databases International Conference on Management of Data archive Proceedings of the 2007 ACM SIGMOD international conference on Management of Beijing, China SESSION: Data cleaning and integration table of contents Pages: 461 - 472 Year of Publication: 2007 ISBN:978-1-59593-686-8 Authors Sergey Melnik Microsoft Research, Redmond, WA Atul Adya Microsoft Corporation, Redmond, WA Philip A. Bernstein Microsoft Research, Redmond, WA ABSTRACT Translating data and data access operations between applications and databases is a longstanding data management problem. We present a novel approach to this problem, in which the relationship between the application data and the persistent storage is specified using a declarative mapping, which is compiled into bidirectional views that drive the data transformation engine. Expressing the application model as a view on the database is used to answer queries, while viewing the database in terms of the application model allows us to leverage view maintenance algorithms for update translation. This approach has been implemented in a commercial product. It enables developers to interact with a relational database via a conceptual schema and an object oriented programming surface. We outline the implemented system and focus on the challenges of mapping compilation, which include rewriting queries under constraints and supporting non-relational constructs.
