New Post: Load TGA Image without using WIC

rosenkostov — Tue, 24 Jan 2012 17:25:45 GMT

Hi, found DirectCanvas recently and it is amazing.

How can I load TGA image nativly supported by SlimDX.Direct3D10.Texture2D.FromFile(Device, String) and attach it to drawing layer?

I have one more question. I need to extract raw bytes from a DrawingLayer in BRGA or ARGB buffer after I render something on it.

Thanks.

Charts with sensible performance comes to mind...

Ok, so pulling the latest from codeplex on my Windows 7 64bit laptop (vs2010) I get working samples! :)
Though, this ultimately should work on my vista machine correct?

Thanks,

@davehorner: do you have the .NET 4 runtimes or Visual Studio installed?

Additional information that might be handy, I did notice that the handle coming back from IntPtr GetSharedHandle(SlimDX.Direct3D10.Texture2D Texture) was negative (-2147419200). All the other parameters looked OK to me.

I installed the directx_Jun2010_redist.exe as linked on the home page. I also tried installing the VC++2010 runtimes found here:

Microsoft Visual C++ 2010 Redistributable Package (x86)
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a7b7a05e-6de6-4d3a-a423-37bf0912db84

When I tried to run WindowsFormsTest, I found that it referenced a Wildlife.wmv and failed, I placed a file there...
I now get this:
a TargetInvocationException when doing _touchHandler = Factory.CreateHandler<Windows7.Multitouch.TouchHandler>(panel1);

I am running on a Vista Ultimate 32bit OS, so that means I won't be playing with that sample on this machine....

So, I then went back to the next sample, WPFTestApp, when I run it, I get the following Direct3D9Exception (E_INVALIDARG) on
E_INVALIDARG: An invalid parameter was passed to the returning function (-2147024809)

Any thoughts on how to get past this error?

PS> your dnn article linked on the DirectCanvas home page for the DXVA checker is full of bad links, you might want to remove that reference on the DirectCanvas homepage.

In addition to the DirectX runtime noted on the project's home page, apps built with DirectCanvas require the VC++ 2010 runtime. I built some sample apps and deployed them to a "clean" machine. No luck until I installed the VC++ 2010 runtime. I used v 10.0.30319.

New Post: Adding elements dynamically

jdsmith99 — Sun, 03 Apr 2011 02:13:09 GMT

Very cool project.

Any suggestions on adding visual elements at run time? I can think of several ways to do it, but any guidance as to what you think is the best way? For example, if I create a particle simulation, and I want to allow users to, click the mouse to add a new particle to the system...how should I do it (add an additional particle)? Something like a method on my Scene class? Wasn't sure if there was something in the library to handle a case like this or any big gotchas to watch for.

New Post: DirectX9 Support?

LukasFellechner — Fri, 25 Feb 2011 23:23:11 GMT

Hi Jer,

thanks for contributing this project, pretty amazing stuff you got going there. I tried to get this running at home, but first I stumbled over the DX10 HW requirement. On my other machine I could get it running then. While Direct2D is DX10 based, MS put quite a lot of effort into making it still compatible with DX9 HW by using the D3D10Level9 layer. By lowering the FeatureLevel parameter in the device creation call, you can create a DX10 device even on DX9 hardware, and most of the stuff will be HW accelerated.

This however does not work with your solution, because you are using version 4.0 pixel and vertex shaders for your SpriteRenderer. While the SpriteRenderer seems to be highly optimized, offloading the transform calculations to the GPU, you are loosing big part of potential users. Lots of users have rather powerful DX9 cards, yet they cannot run your code at all. Are you considering to add a second rendering path using version 2.0 shaders at some point?

What are some potential uses for this?

Did some more tests.

On my other Windows7 32bit (i7 with Asus EAH6850 1GB gfx card) WPF example works fine. But on my Windows7 32bit (Quad core, GeForce 8800GT gfx card) the WPF example is "black" (audio plays) strangely WinForms example works. Running 62889 version

Hi Jer,

"WindowsFormsTest" works just fine but "WPFTestApp" is just black, nothing happens (buttons or touch).
