Va a tope durante 200MB q es muy poco pero luego se pone a 15de bajada y 6de subida. Yo lo uso con el PC y hombre es lentillo pero bueno... Yo m quite la línea fija y el ADSL. Yo tengo el 3GS, ten cuidado a ver si te dan gratis el antiguo q es una patata. Y cuidado con la tarifa por defecto, Ponte la "simple" 9cent llamadas y mensajes No te va a decepcionar, ni Movistar ni el servicio.

I follow the web site of "Real Time Rendering" mmmm I need to take a look to this book for AA.

I didn't see your new posts until now. They look great! the thing I love of ssao is that its performance is geometry independent and the results are very impressive, being an approximation technique to global ambient occlusion and actually to global illumination. also I think that your pipeline is only slightly modified to introduce this technique (because it is a shader itself), so you can provide new cool graphics to your old game (teorically) with a little modifications :) related with AA, wow, it's incredible the lot of things and stuff related with antialiasing. you can write several thesis with the different techniques used for it. (in fact they have been written). in the last technicall book I bought, realtime rendering 3rd edition, there are more than fifty pages related with AA, I remember. Hey!

In OpenGL for PC the implementation is not in client SIDE, but, I'm sure that this functionality is really optimized. Maybe in OpenGL ES, all this operation is in client side. Anyway, is a little stupid trick for to do matrix multiplication without using ASM code. I do all this in CPU and I believe in the compiler! :) (sometimes maybe this is a bad idea :P) It’s true.

Normally the people use GPU Vertex Shader skinning, but with this approach you can use for normal matrix multiplications or for example with OpenGL ES 1.1 for iPhone where shaders don't exist.

How much faster is this way? Does usually have the GPU enought time to do this stuff in a real rendering scenario? Mmm, interesting…
