You can increase the FPS and it should still look natural, but this will decrease the overall performance, because will have to redraw it more often. But still if it's not a problem for you, why not.

Thanks for your comment.

Thanks for sharing this. The smoke effect is very good, and very similar to how smoke moves in real life. Is it possible to change the way the smoke moves by increasing the number of frames per second? Or would it end up looking unnatural?

Very cool effect and it is great that you are willing to share it with the community like this. One questions I had was do you have any sample source code doing this in VB.NET? I'm a VB.NET user and I love to see tutorials in this language as opposed to C#. For example a tutorial like this one - that explains conditions in VB.NET is very helpful.

Ah ... sorry. What I forgot to mention is:

The alternative approach provided works because the CompositionTarget.Rendering event is called by Silverlight 60 times each second.

First: The idea is brilliant.

Regarding your coding in the CompositionTarget_Rendering handler I would like to provide an alternative approach to implement a frame changing on "frame per second" basis:

01.Private cnt As Double = 0

02.Private ccnt As Double = 0

03.Private totalFrameCounter As Integer = 0

04.Private fps As Double = 24

05.Private Sub MakeSprite(ByVal sender As Object, ByVal e As EventArgs)

06. ccnt += 1 / 60

07. If ccnt >= (1 / 60) * 60 / fps Then

08. cnt += 1

09. imScene.Source = New BitmapImage With {.UriSource = New Uri(GetImageName(cnt), UriKind.RelativeOrAbsolute)}

10. If cnt = 118 Then

11. RemoveHandler CompositionTarget.Rendering, AddressOf MakeSprite

12. cnt = 0

13. End If

14. ccnt = 0

15. End If

16.End Sub

Best regards,
