luz que no corresponde - 01/20/14 08:08

Sorry but not Inglish.
Hola, si alguien de habla hispana me pudiese ayudar se lo agradecería.
Estoy haciendo un salvapantallas, y tengo un problema de iluminación, en el siguiente link esta el código y los objetos del salvapantallas,"https://www.dropbox.com/sh/t4w9mu0g385578h/L3At2mt0Ks" si lo ejecutáis, veréis que las patas de la mesa reciben luz, cuando no debería ser así; ¿Cómo puedo resolverlo? Y ¿Cómo podía mejorar la iluminación general?.
Gracias.
Un saludo Jumpu.

Aupa Jumpu,
recién te he contestado en gameartspain y he visto este post.

Salud!

holy fuck this is looking great!

thanks!

homemade antialiasing and a bit of depth blur

250 FPS... what machine are you running? will you be releasing the project files when you're done? I love the look of it! this could become an amazing 3D adventure game

Unfortunatelly I don't own the models. I will talk to Jumpu...

Looks indeed fantastic! Only the candles still have some pixelated edges which hurt the overall result/ look.

Thanks!

I'm not able to properly blur those candel pixels with the actual antialiasing approach (border detection + gaussian blur). Time to try a supersampling render chain.

Full screen supersampled antialiasing. Much better laugh

Silly me was applying ambient occlusion layer after supersampling

Okay. Pretty cool.

But the problem with your method of anti-aliasing is that even though it looks better than no anti-aliasing in screenshots, it sometimes makes aliasing more noticeable in motion. It looks like the aliased lines are "walking" when you look from certain angles and slowly rotate the camera.

It also seems to me like SSAO(or some other effect) is 1 frame behind.

looks really awesome, but it doesn't look like ssaa to me (wrong offsets / wrong downsampling?) tongue

edit:
oh and just in case you didn't know: wrs doesn't prevent curious people like me from looking at your shaders (use pre-compiled shaders instead):

Not really a problem. You can download the same files unpacked in the original spanish topic. The main problem here is the propiety of the models that I don`t own.

It is not really a SSAO, but my personal approach. That is why I'd say strange not wrong xP

sorry, I was talking about the supersampling (-antialiasing), not screenspace ambient occlusion grin

@Kartoffel
You are totally right, sorry. I botched the supersampling xP

now the supersampled image looks as expected
Code:
float2 texCoor = inTex.xy / 2.0;
texCoor += vecViewPort.zw * 0.25f;
finalColor.rgb = tex2D ( mtlSkin1Sampler, texCoor.xy ).rgb;




and this is the downsampled image
Code:
float2 offset[4] = {  1,  1, -1,  1,  1, -1, -1, -1 };
float2 texCoor = inTex.xy*2.0f + vecViewPort.zw*0.25f; 
float2 fScale = vecViewPort.zw * 0.125f;
for ( int i=0; i<4; i+=1 )
{
	float2 Offset = offset[i].xy * fScale;
	tex.rgb += tex2D ( mtlSkin1Sampler, texCoor.xy+Offset.xy ).rgb * 0.25f;
}

What about HDR for the candels?

Looks great!

Re: the epilogue of a success - 01/24/14 15:08

nice but the shading of candels is not smooth from a close view, I mean they look not round.

Stunning! I'm amazed that it's 3DGS laugh Keep up the good work!
