Hello, The Voronoi implementation is great. Can you please provide some suggestions on getting co-ordinates of the polygon for each site?
Thanks!

The function Core.Util.GetArray uses a static array to lower array allocation costs, but newer version of SlimDX (currently I'm using SlimDX 4.0.13.44) seems to expect a array of exact length needed.
For example, in LightingDemo, running this demo will throw a NullReferenceException, located at this line:

_fxPointLight.SetRawValue(new DataStream(array, false, false), array.Length);

With the help of the debugger I found that all fields of _fxPointLight became invalid. A watch on _fxPointLight shows that the change happens just after the _fxDirLight.SetRawValue call. So I canceled the static buffer and tried to create a new array of len bytes each time, and this modification worked. I suspect SlimDX neither fully checks the parameters nor handles this situation well and internal states of D3D just crash.
This problem also affects other several demos.

Thanks for you! I foung this yestoday. I only use compile fx directly instead of use fxo. I find your sample is very good. it's great helpful for me. So i want run your sample When i compile the sample with VS2012 .It report error about this "错误 6 命令“cd FX

I don't kown how solve it . can you help me. Thanks, my english is very bad.

Well, good tutorials, and good repo, Mr. Richards, thanks.

I tried to run some examples and found EndOfStreamException is thrown in many of them. The debugger shows it is in the Core.Model.TextureManager.Create1By1Tex method, this line:

db.Data.Write(color);

I commented this line and the code works fine. Is setting the color of this pixel really necessary, or it is a defensive measure? I'm not sure why it throws an EndOfStreamException while "trying to read" (as the debugger prompts).

I suggest updating read me to a link to this:

Lets us see a preview of the tutorials online before downloading the whole thing.

Hi Eric,

Thanks for the awesome code, it is really helping me make the move from XNA.

I am having a small issue in the LightDemo project, perhaps you can explain why.

In the DrawScene method you have the following code:

var array = Util.GetArray(_dirLight);
_fxDirLight.SetRawValue(new DataStream(array, false, false), array.Length);

All is well until it tries to set the array as "Util.GetArray(_pointLight)" and call _fxPointLight.SetRawValue()

At the SetRawValue call an object reference error is thrown by SlimDX.

I looked it up and came across that section of the tutorial. Someone left a comment there saying that they had a similar issue and that they resolved if by initializing a new array with the size [1024] for each of these calls. I tried that and it did not work (Same Error).

Please let me know if you can help and thanks again for the awesome tutorials.

Regards,
George
