"post glow screenSize" and "post glow fixedSize"

[xtormlab]

hi

i'm new in HLSL

i've tried 2 shaders from nvidia shader library : "post glow screenSize"  AND  "post glow fixedSize"

( http://developer.download.nvidia.com/shaderlibrary/webpages/shader_library.html )

they are quite similar

the "post glow fixedSize" works just fine, i can easily make it available

but the same code won't fit the other one.  I can never get the "post glow screenSize" to work, this effect just didn't appear at all

which confused me all these days

does anybody have any idea?

Can you post your debugfile? Is everything loading like it should, and are there no other errors?

I'll try it myself as well, hang on, i'll be posting here in about 30 minutes i hope.

OK, i tried it.

The screensize one works, but you'll have to set the technique you want to use. I'll give you an example code of how i'm doing it right now. It's a bit sloppy, i put it into a quick template of mine, so i'm declaring the rendersurface and shader just before the loop. It's good though, since it'll be easier to read for you. I didn't make any changes to the HLSL shader found on the nvidia page, i just copied it straight. Also make sure you've got the include folder in your application folder. The include folder is found in the *.zip file from the nVidia shader. Hope you'll enjoy it

Code:

public void Main_Loop()
        {
            TVRenderSurface RS = Scene.CreateRenderSurface(TV.GetViewport().GetWidth(), TV.GetViewport().GetHeight(), true, CONST_TV_RENDERSURFACEFORMAT.TV_TEXTUREFORMAT_A8R8G8B8);
            TVShader GlowShader = Scene.CreateShader();
           
            GlowShader.CreateFromEffectFile(Application.StartupPath + "\\Shaders\\abc.fx");
            GlowShader.SetEffectParamFloat("GlowSpan", 2.0f);
            GlowShader.SetEffectParamFloat("Glowness", 2.0f);
            GlowShader.SetEffectParamFloat("Sceneness", 6.5f);
            GlowShader.SetTechnique("Glow_9Tap");
           
            RS.SetNewCamera(Scene.GetCamera());
            //TV.SetAntialiasing(true, CONST_TV_MULTISAMPLE_TYPE.TV_MULTISAMPLE_4_SAMPLES);
            while (blnLoop)
            {
                CheckInput();

                RS.StartRender();
                Scene.RenderAll(true);
                RS.EndRender();

                TV.Clear();
                Screen2D.Action_Begin2D();
                Screen2D.Draw_FullscreenQuadWithShader(GlowShader, 0, 0, 1, 1,RS.GetTexture());
                Screen2D.Action_End2D();
                TV.RenderToScreen();
                Application.DoEvents();
            }
        }

PS. Not the 30 minutes i hoped for, but i couldn't fix it myself at first either.

No problem, glad i could help out
It was a good training for me as well
I'm still experimenting with shaders, still in the learning progress, so i thought i'd best give it a try Found the mistake by accident. I suddenly saw there were 2 techniques, so i wondered if it needed to be set... It did:P
