AGI32 and Relux? What are they?

[Jaguar lover]

Leora and all readers!

 

I don´t know or even heard about anyone using Inspirer. On the other hand I only know of two People in Sweden (I am one of them) using Radiance(Any Swedish Radiance users out there?) for lighting simulation.

 

For lighting analyse I use Dialux and Relux. Relux has an additional module - Vision - that is radiance based. (Anyone none european using these?)

 

As far as Image quality/Lighting visualisation I would wote Lightscape as the best. I cant say I am too pleased with VIZ 2006/Radiosity.

Maybe havent given it the time either.

 

I must say Lighting analyse software has come very far considering visualisation, Daylight and ease of use since I began using them in the 1997-ish.

I agree completely. I think renderers push lighting software programs to do more visually, especially photorealistically (is a photo real? ) and lighting software pushes back ,a little, by having more rendering tools exhibit some lighting analysis tools (psuedocolor, point luminance).

 

I have a hard time stating that LS is the best. The architectural images I've seen from Vray, and many of the Maxwell gallery images, rival LS images. Many VIZ images are also very realistic. My 2p, for what its worth.

 

I think the skill of the designer "birthing" the image is paramount. So much of what makes a compelling image is subtle and detail oriented. Its easy to mass model and get the lighting right (once you understand photometry), its the texture, specularity, scale and a sense of style that makes the image pop. Software programs provide only a toolset, they can't make someone a designer. But an artist/designer can push any software tool to do its best, if they understand the building blocks it provides.

 

Science and art! Isn't this a cool industry we're in?

 

So, may I ask, why do you use Dialux/Relux if you use Radiance? Radiance has so many more capabilities, is it just a matter of time? When do you differentiate, in other words, is there a certain model complexity or time comittment, or feature that drives you from one to the other? I'm curious.

Leora!

The reason I use Dialux and Relux instead of Radiance - clients money!

I only use Radiance in large and/or complex projects or when the client asks for images.

Every day lighting design is carried out with "ordinary" software as Dialux and Relux.

 

Of course Vray,MR and a bunch of other render engines are capable of producing good images, but you can control the secondary "light"bounce and override laws of physics. That´s the reason I point out Lightscape as the image quality winner within the (as good as it gets)"physical correct render engines".

 

And when physics doesnt matter, then the (good)artist 99% of the time outperform the "physically correct render engines" in photo real image quality -regardless of software. ( I suppose we agre on that Leora)

The last post in this thread was about two years ago, and MWR still doesn't allow for IES (or any other) photometric light source. Was/is it ever intended to be added?

 

on a second point can anyone advise on the practice of using IES2RAD and building imposter geometry for use in Radiance/Learnix?

 

Relux 2007 with the Radiance plug-in now has extended Radiance features (but it is still not as good as Radiance itself)

 

Dialux is still using the POV Ray render engine

 

AGI32 I've not tried as the cost would not be supported by my employer.

There are a lot of things that Maxwell was supposed to do; IES support was one of them. It was also supposed to have some kind of lighting analysis tool implemented at some point but I don't think we'll see that until version 2 is released. Maxwell is still physically correct and you can model each fixture to give you the same results as IES lights give but it's going to take much more work to do so.
