This is a test I did, inspired by another lens test in this forum. The light in the upper part is a flare.

Another useful extension would be "sample white point", which is common in converters for camera raw formats. By clicking in a region which is white(-ish) in the image the white point is set from the chroma values at this point, which makes it white in the final image. I think it is possible to just...

Hi, I would like to see a logarithmic scale on the pre-scale and post-scale sliders, so that the sliders have a range from -10 to 10, which is evaluated as postScale = power(2, sliderValue) This would give better control for small values (<< 1) which are difficult to set with the current implementat...

wat must i do with the code to be able to save as igi?

lol told u

infile.txt -> set "save_igi" to "true"

That should work.

Yes, Java and C++ are fairly similar, except in Java you write all code for a class in the same file. And all memory management is very different. And speed, when you run it (though I think its pretty fast nowadays)

Hi, I wrote an implementation of this format so igi files can be read from Java. /* * Public Domain. * * Note that this piece of software may be unfinished or buggy, or both. * */ package igi; import java.io.File; import java.io.IOException; import java.io.RandomAccessFile; import java.nio.ByteBuffe...

Thanks,

Could youd add the endianess of the ints/floats etc, and the specific order the color values are stored (R,G,B or B,G,R).

@OnoSendai: The model approx 0.1 units high (from AABB), I scale this in the model element by 2.8, so it becomes 0.28m, from the lower neck to top of head. The epi thickness is pre-divided by 2.8, so the scaling should make it correct. Thanks all for comments and input. I'll try the suggestions and ...

Remember that the paper's using a very different rendering method. In theory everything should work the same (just mlt will be a lot slower), but there will be some differences in look due to the way the materials are set up. ryjo, it might be a better idea to use a 3-point lighting setup with a ho...

And what exactly is this tonemapping? An image (or the computer screen) can only display a limited range of tones (think grayscale). The render contains a much larger range ... the brightest part may be much brighter than the screen can show (will appear as white), and some parts in dark cannot be ...

Cool... Glad to see that a SSS render can clear up well :) The skin doesn't look especially convincing to me, but that may be the lack of fine bump detail throwing off my perception. Thanks, I kind of convincing until you look at it too closely, then it looks like a "doll". I think that a bump to t...

Maybe, it's 'cause of the epidermis is uniform 25mm It should be thinner @ three sites: 1) Ears 2) Nose (exactly the part of your pic^^) 3) Eyelids The paper says it uses 0.25 mm epidermis across all skin, and the examples in that paper look ok. :) See section 3.5 and examples at page 10: http://gr...

Why is this so dark? In reallife i think this wouldn't look like that. Could it be that this is a energy loss related problem? I think that the skin doesn't transmit sufficient light through the nose, so it looks darker than it should. I have used "glossy transparent" material surface, which may be...

You may also want to do some tests with a specular material as opposed to glossy transparent. I've added in bump for glossy transparent for next release :) Sounds great :) I did try specular transparent, but it made the model look like a jar of honey had been poured over the head. :roll: Here is th...

Do you mean the patterns visible on the forehead? Those are more visible the longer the render goes, this has rendered about 20 mins longer. It is a low res model, ~55000 vertices. Yes, those and also those crossing the cheeks^^ So SSS is TOO accurate atm xD Can SSS be normalsmoothed, yet? The stre...
