Hi Mahdi,

Just a quick question - Are you intending to update the lbrary now that XNA 2.0 has been released?

Regards,
Paul

I've not tested performance of these effects. using FxComposer or some other tools i will test performance cost for each effect and make a powerful documentation for it. so i can't recommend to to do this or not, yet.

For your next question i recommend that you apply Shockwave once, change the parameters and apply it again. note that you do NOT need to declare another instance of effect and consume graphics memory., just apply that one twice.
Happy Post Processing.

Sounds excellent - I'm working on a new game and I think as soon as 2.0 is released I'll port my code and grab your latest library.

I see you've added a Shockwave effect - I'm simulating that with an animated Ripple effect at the moment. Would you recomend swapping over to shockwave (performance gains?). Does it support multiple shockwaves on screen at once? - using the same effect or would it need 2 instances of the effect adding ot the pipeline?.

And finally a big thank you for this great library :)

Hi Paul.
First version of the library is ready and i'll release source code and binaries. i will source code of shaders also for both learners and who wish to use the library on 360 since there is no 360 port of post-processing library planned.
so go straight on your xbox project and continiue shading. source codes are comming.
there is no new features planned until February 2008.

Regards.

Hello Mahdi - just like to say hello and thank you for your library.

I'm using the Ripple effect as a shockwave in a little shooter I'm writing called Doppelanger - the effects will be available in the new version (1.1) which is coming pretty soon. Radial Blur also looks pretty good and could be used as a sort of 'stunned' state.

I have 1 issue in that the library is not compatible with the XBox360 so I've had to disable effects on that platform. I did have a look at disassembling your effect code (Effect.Disassemble) and trying to compile for the 360 and also simply reversing the byte orders of your existing byte codes - both times I encountered resource could not be created errors at game run time.

Are there any plans to port it to the 360? If so do you have an estimate on timescales? If not, any chance you could give me a hand converting just a couple of the effects to XBox please?

Regards,
Paul Cunningham
