use ies on fryrender

i can use ies on emitters fryrender? i have a erco light on my interior, how i can simulate the form of this light?

thanks

You need to model the light as it would look in real life
Maybe i can do some test later

Here is my test. Worked quite well i think

Here's an image that can be used as a textured emitter :



Map it on a circle . It works quite well.

Thats another way to do it
I havnt tried it, so i dont know what works best of the two metodes...

Really useful because the units in which an emitter generates light beams are solved by Fryrender and the only is to define the radiation diagram or the way the light is distributed in the 3D world.

The first way looks like enough. With a scene test conformed by a wall and a ground and putting the light near the wall I think is a real valid way to simulate the .ies lights.

Have in mind fryrender2008 that lights in the strict term doesn't exist so the most important are these two factors:

a).-The power of the light.
b).-How the light is distributed and this has been right solved by Stromberg 90 so nicely.

Regards.

Glad that you liked it
Here is a wirefram of the model i used, with guide lines
The emitter is pointing upwards.

I think this mantains really close and with a lot of fidelity to the real world. From its construction to its behaviour.

And from here other users can start to experiment and make other tests in order to get other radiation diagrams.

A question: it depends on the cap of glass (dielectric or ghost?) (shape, form...)in a 90%...

Regards...

The glass it's best to use ghost, the render i did post is with dielectric.. but i tried it with ghost before that and it looks the same.

Ok.

More test, with a new light.
Just for fun actualy

Looks good and great caustics in that last image.

Thanks
And yes they look quite nice

WOW ! Great caustics !
Could you share the water material ?
I seem to be caustic-challenged

Thanks
It's the regular water material, but maybe i could do a quick tutorial on this
