Hi Earnie,
You wrote that "the VisualBrush is non-interactive so can’t interact with any of the object’s on the screen that are being painted on the 3D surface". Is that possible anyway? Can I design sort of a VisualBrush that allows me to interact with the basic controls being rendered upon the mesh?

thanks

Did somebody forget about releasing the source for this? If not, could we get an update?

I would love to see some of the code posted. Any new updates on if/when that is happening?

Thanks

I agree with itprochris..... where is it? I want to see this for real....

Thanks :-D

Update: The code is being updated to the latest CTP now that it has been cleaned up. Nice job on the effect, do you have a screenshot with an image on it?

Something new about the code-sample?

I was developing a similar app for school use, but then I sair this app ,and its amazing!

With some minior changes it would be perfect :-)

I was looking forward to the source code, but I got so excited I couldn't wait. Here is my first hack at the water effect for everyone that's as excited as me about this demo.

Any update on how the code cleanup is going before the source is released? Or the source no longer being released?

Re: PDC Dev Team -- Plasma Screen Application at PDC

Ernie Booth — Fri, 14 Oct 2005 05:53:08 GMT

No date set for release of the code.

Hi Ernie,

Where will you post the link to the download when it becomes

available? Any chance of a time frame?

Thanks, great work!

From memory: A Dell with 2 Dual core processors, 2 GB of Ram on PCI-e motherboard, Dual hard drives and an ATI Radeon X800XL. Is what we used for Scarab.

Lots of memory and a good graphics card. [H]

We had two computers connected to a video switcher both machines were identical in configuration and software. The switch box allowed us to change the output video signal to the monitors from one PC to another.

So when we needed to update the software we'd just switch to the signal to the other PC and make the update.

They were high end DELL workstations with killer video cards. ;-) I don't have the specs handy hopefully Ernie can reply with them.

Nothing in particular. I just wanted to see the how it worked. If you have the footage why not show it?

Sorry to say the answer is no. What information did you want about the setup?

The idea of sending the video out over cat5 is nothing new to me, but i would be interested in knowing about the splitters used. My idea is to add areas to the system. Ie different sections can see different presentations, but then since this is just data driven all screens could amalgamate. It would be a seperate box per section, which wouldn't be too much of a problem.

Excellent job. pm me and we can talk. All credit to yourselves of course but i'd love to implement this.

This is some amazing Stuff guys... also i will take that plasma screen :)

thanks a lot!!
It was an amazing video!
But could you guys post a ~~photo~~ screenshot (with a better resolution than the video) of your application? Because it's so good, we have to see this in good conditions.
Great job!
;)

Indeed, for me this will be the best bit. I will build one of these myself with old monitors and redundant cat 5. We are going to see a lot of new entrants to the world of programming being able to build appz like this. data <=> presentation is now as envisioned.

I will build one of these.

Yes we use a VisualBrush on a tessellated mesh. We use some spring theory to do the simulation. Here is a pointer to the spring theory we used. We keep track of the points for the mesh is a separate class and then just update the mesh’s point collection 30 times a second. Yes the VisualBrush is non-interactive so can’t interact with any of the object’s on the screen that are being painted on the 3D surface, but as you pointed out this isn’t an interactive application so that didn’t really matter. I hope to see lots of cool physic WPF applications [H]

So basically you have a VisualBrush on a flat mesh in a 3D world. When the cool water effect happens, you raise and lower specific points of the mesh to create a ripple effect? Awesome!

There's only one problem that I see. VisualBrush is static. It doesn't support playing with the controls that it draws. Although it works great in this situation, it wouldn't work if you wanted the user to be able to select, say, a news item to view more information, or the video to put it in full screen (now obviously, plasma screens do not have the technology to support touch screens, yet).

Ernie Booth — Sat, 08 Oct 2005 23:04:19 GMT

All the problems we had were due to performance. We used the VideoDrawing class instead of MediaElement for the video, because it has some perf issues in the build we were using. The WPF team is gearing up with performance tuning so hopefully they will have that working much better by RTM.
