[svg-developers] Interactive access to interpolated states of an SVG SMIL animation
Dear all, I'm working with SVG interactive animation for spatio-temporal data. The main feature of the application I'm trying to build is a time- slider capable of interactively controlling a SMIL animation. Thanks to Kevin and carto.net, no need to build the slider, it's already available. Ideally, I'd like the slider to reveal micro-steps, those that are interpolated in SMIL animation. In other words, the slider should dynamically control the whole sequence of a SMIL animation's frames, including the ones that are interpolated. Does the present specification allow such a level of interactivity with the temporal dimension? Is it possible? Who can give me info on this or direct me towards it?

RE: [svg-developers] Interactive access to interpolated states of an SVG SMIL animation
This is an interesting question, but I'm not sure my answer will be interesting
or definitive, but let me go ahead and make a stab at it. If I miss something
obvious then others will likely correct the oversight:
My first thought was that it may be relative to what is being animated. For
example in the case of an object following a path, we may use the path length
methods to figure out intermediate points (see for example
http://srufaculty.sru.edu/david.dailey/svg/curve.svg) but in the case of
another SMIL animation, the fine-tuned control of that object within the
animate tag does not (at least as I think about it now) reveal such.
On the other hand (as some people involved in fakeSMIL have probably
leveraged),
tag id=Qanimate attributeName=something values=a1;a2;...;an dur=k
.../tag is pretty much the same as
function animate(){
code to assign v to proper values of [a1,a2,...,an] over dur k
code to terminate loop based on value of dur, tinytime, repeatCount and a
loopcounter
document.getElementById(Q).setAttributeNS(null, something, v)
window.setTimeout(tinytime, animate())
}
(modulo my imprecision)
so another function which takes a parameter from the slider and simply moves
setAttribute of Q to something, in one static moment would probably accomplish
exactly the same thing.
Of course, if the animation is complicated by having multiple attributes
animated for differing durations and the like -- there would have to be a chunk
of code using the above approach.
Can anyone thing of a more purely SMIL-y solution?
cheers
David

Dear all,
I'm working with SVG interactive animation for spatio-temporal data.
The main feature of the application I'm trying to build is a time-
slider capable of interactively controlling a SMIL animation.
Thanks to Kevin and carto.net, no need to build the slider, it's
already available.
Ideally, I'd like the slider to reveal micro-steps, those that are
interpolated in SMIL animation. In other words, the slider should
dynamically control the whole sequence of a SMIL animation's frames,
including the ones that are interpolated.
Does the present specification allow such a level of interactivity
with the temporal dimension?
Is it possible?
Who can give me info on this or direct me towards it?

[svg-developers] new SVG Editor
Hello all, We at inEvo (http://inevo.pt) are developing a SVG framework for actionscript. This framework allow us to create Rich Internet Applications to create or maipulate SVG drawing and elements. Applications to create top-view interior designs and also Bars, concerts and events planners are some of the possibilities. Meanwhile, we are doing a SVG Editor. The first preview is available at http://blog.tiagocardoso.eu/mainada/comics-sketch/2008/11/02/svg-editor-preview/ I'll be posting a live demo of it soon on the same blog. This would be useful to create SVG code quickly without resourcing to heavy applications like inkscape, so you can test on your own SVG applications. Could you send any feedback regarding this preview and any opinions ? Thanks to all of you.

Re: [svg-developers] new SVG Editor
Wow, very impressive! I like the pattern matching component that lets you transform paths into basic shapes. It also seems quite fast, certainly much faster than the other pure JavaScript-and-SVG editors I've seen. I'm looking forward to the live demo, Jake On Mon, Nov 3, 2008 at 7:15 PM, Tiago Cardoso [EMAIL PROTECTED] wrote: Hello all, We at inEvo (http://inevo.pt) are developing a SVG framework for actionscript.

[svg-developers] Re: Interactive access to interpolated states of an SVG SMIL animation
When the slider is moved, you can call setCurrentTime() on the root element http://www.w3.org/TR/SVG11/struct.html#InterfaceSVGSVGElement First you'll have to call pauseAnimations() so the animations will not run when the slider isn't moved. If you need to obtain any values for the time to which you slided, then use the respective animVal instead of getAttributeNS(). One problem which arises is how to determine the time span which the slider should parametrize. Animations can loop indefinitely, so there is no global end time for an animated SVG. --- In svg-developers@yahoogroups.com, tim.becker80 [EMAIL PROTECTED] wrote: Dear all, I'm working with SVG interactive animation for spatio-temporal data.

[svg-developers] Performance of scripting in current browsers
Over the last few weeks, I've been doing some performance testing of the SVG display tools I currently have access to. While I don't have conclusive results yet, some of my results have surprised me. The last time I tried anything close to this, browser results were pretty bad. But the current results are much better than expected. I'm showing the 1.8 pre-release of Squiggle (Batik) is by far the fastest (by a factor of 2 to 4) for the kinds of tests I'm doing. What I found really surprising is that Firefox 3.03 is currently a little faster than Opera 9.6 in my tests. I'm running my tests on a 1.66 GHz Core 2 Duo running Linux. The SVG files I'm testing are instrumented versions of http://anomaly.org/wade/projects/svgplay/wuse.svg and http://anomaly.org/wade/projects/instruments/Instruments.svg I'm currently trying to generate something resembling a reasonable summary of the information including documenting my methodology and tools. I'd also like to add more display applications to the mix to get more of an idea of relative performance. (Unfortunately, Chrome is still not available under Linux.shrug/) G.

On my winXP machine Opera 9.62 uses about half as much CPU as Firefox 3.03 to run the wuse.svg file. How are you measuring the relative performance?
