First, congratulations on doing a great job with SP1.

Now my question:
David, at 21:11 you mentioned that the integrated DirectX could also be used for wireframes.

After some investiation, the only thing I saw was a new D3DImage class (btw. it is very usefull). But it is not appropriate to create a 3d lines and wires.

So is there a way to use the real DirectX 3d lines or do we still have to use workarounds like ScreenSpaceLines3D and similar (use triangles to simulate lines) which are quite slow?

Thanks! But now where are the rest of the sample code of the video?

And again, it's been more than a month since Part 1. I may sound to be bad, but why can't I simply have the codes soon?
I think it doesn't matter for me if the code came directly enedited from David, instead of waiting for you to post the code, and it's been taking too long time to wait.

Apologies for the long wait, now that SP1 has shipped we can celebrate by spending sometime on shipping the source code for these demos. You can find the first batch here: Teitlebaum's WPF Graphic Demos, Part 1

Hooray! :)

I really like this video! So much! But now it's been more than 2 months, and where's the source code of this demo?

Hey Adam and David, even now .NET 3.5 SP1 and this includes WPF 3.5 SP1, has been released, where's the demo code? Please don't make anymore promises.

We want it now.

Thanks for all your good work. I can't get a player created by EE template to link to a video source on a WM server.

Regarding this earlier exchange:

Hi Tim
Great screen cast, Thanks sohbet.
Dou you know what it will take to make a custom media player, that plays a streamed vide file.

jakob: the samesohbet odaları media player will play streaming URLs mirc as well -- just change the mediaUrl attribute in the javascript file to your URL for the stream mirc (as long as the stream is a windows media stream)

Sorry, but I can't web hosting find a mediaUrl attribute in any of the js files that EE creates. There is a mediaSource msn ifadeleri attribute in the MediaDefinition.xml file, but changing that to an URL does not work.

Sorry if this has been answered çet odası elsewhere. I have looked.

The source code for this demo would be really cool!!!
More votes for source!!

hello again....

i am very disappointed at the moment...
since the void SetBackBuffer(D3DResourceType backBufferType, IntPtr backBuffer)

which takes an IntPtr as a param, necessitating full trust. :P

Fantastic demo. I have a quick question re D3DImage: Will it work in an xbap? In other words, if you have a managed dx9 rendering back-end, will it fuse with the new dx interop without requiring full trust?

Thanks.

Hurry up and post some sample files :P I want to play with the demos.

It looks like you guys have done some really good to me, I'm really impressed. The next Office, Windows and everything else should be fantastic thanks to this technology.

Adam,

Very nice work indeed. What should I use if I wanted to access TV functionality from a TV Tuner card? Is that a DirectX only route or can something be done from WPF?

Thanks.

Right, the multipass shader effect class has been cut and won't be in the final builds of WPF. If any of it is in the beta, it's just a stub.

MultiInput effects *will* be in the final release, but shouldn't be in the beta.

sweeet :)

also i vaguely remember you saying that there wasnt any multipass support for pixel shaders? but what about the MultipassShaderEffect Class? is that depricated or something? or am i just wrong about the multipass stuff? :) i noticed that MultipassShaderEffect doesnt have a RegisterPixelShaderSamplerProperty method or any pixelshader(s) property though.. can you elaborate on how that works? :)

In WPF3D we haven't yet added a mechanism to use a custom pixel shader when your 3D object is being rasterized. The new effects are applicable to UIElements -- ie 2D.

That having been said, you could use a our new DX Interop (D3DImage) and do whatever you wanted in 3D, but I gather that's not exactly what you wanted.:P

(yet) another question :) how about pixelshading for 3d models? is that possible somehow? since there is now a pixelshaderwrapper with constants and stuff, the step shouldnt be to long i'd imagine (but what do i know:P)

Multi-input effects didn't make it because we ran out of time in our compressed release schedule to get it implemented and tested properly before we released. In the grand scheme of things we nailed the most important effect scenarios with the features we did get, so the loss of multi-pass was not a deal-breaker. :P

oh ok :) can you talk anythign about why it was cut? it seemed like a good idea to me :) but i guess the panel (or something) with an effect containg another panel with another effect works as well but it just seems a little more cumbersome to me :) but im sure you have another trick up your sleeve :)

havent found anything about multiInput so far but i figured you'd just register more DPs as sampler properties and hook them onto diffrent registers (can you do that by the way?) :)

We're just now in the early planning stages for the post-SP, so nothing has really been decided yet. ;)

ok :) any thing like that in the works post sp1? i guess perhaps you could apply a visual element and then try to massage the normal data into the shader with a property or something :) but that sounds hard :D

oh, im sorry thats not what i meant :) i realise that the time to get stuff in the beta was limited and if you had gotten everything in, it whouldnt be a beta :) no i ment, why was multipass shaders cut :) (you awnserd this below)

Why can't you guys remember to post a link to the LOW-RES file on every video that you do? :@

It's very irritating when downloading with BITS to have to wait on 600Mb files.
