Comment by kingjin on July 22, 2013 at 8:07am: Nice rendering, is what does this engine , how long , thank you.

Comment by Dario James on July 22, 2013 at 1:17pm: gracias el motor es path tracer y unas 35 horas de render con algo de iluminacion ies

Comment by George Ioannidis on July 22, 2013 at 10:20pm: It is beautiful rendering! Really fantastic!

I hate TVs in bedrooms! :)

Just one thing: 35 hours of rendering for me is really unacceptable time. Even 10 hours would be too long. I don't know if it is practical for architect to wait 35 hours to get the image and then need another 35 hours if customer says: should we have alternate view with wooden floor and blue curtain? It is obvious NXT has reached very high level of rendered image quality and realism but now it is the time to have a deep look at the speed and have some significant improvements. Furthermore, when all the other competitors and rendering software developers are moving that direction.

Comment by Dario James on July 22, 2013 at 10:45pm: gracias george lo deje 35 horas por que no tenia que hacer otra cosa y cuento con otra maquina alternativa que aun no las puse a trabajar en farm, y si no tuviesemos televisores en las habitaciones triplicariamos la poblacion mundial....

Yes, farms and other stuff are good, but relatively expensive. I was talking about taking benefit of any existing (and really not expensive) hardware all of us have: the really POWERFUL GPUs. The cost of one good GTX770 is here about 380€. You can then put two of them into a single machine in SLI configuration and could have real rendering beast on (or under) your desk for less than 800€! Hundreds of cores (on lower MHz rate, but literally hundreds of them, 770 has 1536 cores) cannot be beaten by any mean in that price level. NXT must go that direction.

Comment by kingjin on July 23, 2013 at 3:31am: This time is too long , there is no way to accept this time , NXT to improve the rendering speed on the job .

Comment by Roy Hirshkowitz on July 23, 2013 at 8:22am: George- try one of the GPU-based products out there and see before you start making these sorts of assumptions. There's a lot of hype around these but a lot of problems and limitations. They work great for simple stuff but fall apart when given the sort of complex problems our users present. The programming task is also massive and may require starting again with many limitations. For example not all (or any?) of our existing engines are GPU friendly.

Comment by Jorge Javier Lara Domínguez on July 23, 2013 at 11:15am: En mi experiencia, nuestros problemas con el tiempo, son debidos a problemas de iluminacion propios de nuestros modelos. He notado con mis trabajos mas recientes que el manejo de una mejor iluminacion (he estado usando archivos IES, que me han dado resultados satisfactorios) mejoran el rendimiento en menor tiempo para resolver mis modelos, incluso empleando mapas de desplazamiento los caules como sabemos ralentizan el proceso. Otro punto importante es el manejo de los materiales, Peter Milner comento, de manera muy acertada, qeu todos los materiales poseen cierto brillo, al emplear este principio en mis modelos he necesitado menos pases y menos tiempo para qeu se resuelvan satisfactoriamente. Saludos a todos.
