No Problem.
Oh, btw: He later said, he's working on the post-process bloom right now... There might be a change with it, soon

I have to make a REQUEST on Reinhard Tonemapping:
Please implement it this time in way that indigo(blendigos) and violets values match.
So if I open the igi file in Violet and enter the same values as in Blendigo I would like to see the same tonemapped image.
It drove me crazy last time I played with it - then someone said that this is simple another way of implementation.

please keep the variables acting the same way.

Vienna:
yup, I've added a switch to make it work the old way. same with linear, you can either use exposure/contrast or gain/exponent.

Ack, problem occured at my house so havent been able to respond, but yes the GUI is done, i just have to add a simple API to get the values from it. you can PM me a password for the commit or i can attacht the files to the forum, whichver works.

I am talkin about Reinhard Tonemapping with the values Pre, Post and Burn. In the current Violet.exe they do not work the same way as in indigo.

Did I make myself clear now?

yes, I've done exactly that. It'll work either way.

@dougal2

Heya Doug, I gotta small request for you. Could you please implement
an automatic reload feature into jViolet? What I mean is, that jViolet
recognizes if an igi is updated and reloads it automatically. I dunno if
this is possible with Java tho. With C++ under Windows it is possible,
I dunno how but somehow it works.

If you can't get it to reload automatically, then please implement a reload
button. This would save a lot of clicks and then we could just use indigo's
console and jViolet instead of Indigo.exe itself. Right now it a tedious job
to load an igi and play with it during the render is still going on. I would
appreciate it a lot and I guess others too.

In the end it doesn't matter if you can do it automatically or manually by
pressing a reload button, both ways will make the usability better!

Thanx in advance mate!

p.s.

I will not count the word 'automatically' in this post.

take care
Oleg aka psor

a "reload last" button is possible.

Sounds pleasing, so thanx! Maybe later on you guys can pimp it to get
loaded automatically ...

btw. EXR output possible with Java or not?

take care

As far as I can tell, EXR is a no-go with java, as it's a c++ library.

Maybe it can be hacked to be loaded as an external from Java, but that's a feature to look into at a later date.

EDIT: actually, thinking about it, using an external library would make it platform-specific, therefore defeating the entire purpose of jViolet.
So no. EXR support will not ever be possible.

Alright mate! Then you might wanna keep an eye on the sunflow forum
to get ready when the Java port is done.

p.s. You don't have to hide pal!

edit: I meant this line: "* Full OpenEXR integration (pending on MarioF's amazing port)"

edit2: Hold on a sec ... Ian has HDR output in Radium, that would be
great to have then! Because it's HDRI too, just a "bit" bigger ... hehe. ;o))

take care

I have found the EXR binary specifications. It's possible to do in Java, it'd be very time consuming to write the parser though.
It's _way_ more complex than IGI.
