AccuRender nXt

advanced rendering for AutoCAD

Hola a todos, quisiera saber si alguno de ustedes a ensayado trabajar con hdr, y transformar jpg en HDR, yo he visto excelentes resultados sobretodo de Peter Milner pero no termino de comprender como es eso de que la luz proviene del hdr ¿Cómo se mide? . Si alguien tiene información sobre este punto asi como como se comportan los backgrounds reflejados o refractantes y puede colocar unos ejemplos seria excelente. De antemano gracias.

Saludos,

Alejandro

Hola, estoy haciendo los primeros ensayos al transformar imágnes JPG en HDR, lo que si he visto es que he tenido que trabajar los HDR individualmente para bajarles muchísimo la intensidad de luz, esto lo entendí después  que Roy posteo una respuesta ante un problema  que le había planteado, quisiera saber quienes han ensayado lo suficiente con HDR (por cierto que me encanta el resultado). Saludos, Alejandro

Just to clarify--

 

I needed to reduce the intensity so much on your hdr in the previous example because the hdr conversion routine is aimed at producing a brightly lit daylight image.  On the other hand,  your model was being lit by an HDRI which was created by Paul Debevec in a dense eucalyptus grove.  That mismatch in lighting data accounts for most of this.  There also is some inherent inaccuracy in this procedure anyway, which I'm sure also contributes.

 

Thanks Roy,   I make my own HDR (trial and error)   Do you use some software to get accurate results? or we have to do our own trial and error until we got something  that looks good?

I haven't tried playing with the settings in the convertor-- it's very convenient just to use channel 8 if you put the thing in WalkAbout.

Después de 109 pases, trabajando con HDR y path tracer esto es lo que obtengo, he tenido que utilizar un valor bajísimo al salvar el jpg como HDR y además el valor del canal donde coloqué el HDR también es bajo

Looks nice.  The geometry of the first window mullion doesn't look correct. 

It may be difficult to resolve all of the noise in this one.  It's possible you'll end up reverting to the standard engine-- we'll see.  If that does occur, remember to tag materials as glossy where appropriate to help performance.

 I already assigned some materials as glossy.  I am re-starting again, thanks for all your help. I would let this image at least 300 passes and see how it goes.

The glossy switch won't matter to the Path Tracer-- it will be ignored.  It will matter if you decide to use the other engine.

Acá esta la imagen después de 1000 pases, 12 horas de procesamiento en un Core Quad con 4 GB, Windosws 7 arnxt 64 bits,  HDR, sol, luz indirecta, dos luces internas, varios canales para controlar la iluminación

This is a remake of one of Peter Milner's scenes. I dont have the file. I photo-matched it in sketchup and rendered in nxt render for autocad.I just retouched it and increased the resolution.
