New version

>> v0.99u.26 is up! Fluid behavior improved!

Great! It looks like you optimized the fluids very well Taron!! I can work wihout any slowdowns and with the bigger canvas now (2560x1600)! Good job!

SWEET!

Ive been playing with the most recent version and I noticed it feels more sluggish and it is creating those straight lines when drawing the stroke.
I tested older version u20 with same settings and it is much smoother...no straight lines in stroke. See attachment.

I have mixed feelings about the new fluid behaviour....not that its better or worse...just that its different
especially when you crank the fluids and use it more like inks.
I know it will be forever changing as it develops so iM TRYING NOT TO GET TOOOOO ATTACHED

I hope at some point that you will be able to ad a few clear basic controls for users..since it is all about the fluids
Basics such as .....

Inertia ( how much brush direction momentum is transferred into paint)
Drag ( how quickly it slows down )
Spread ( inertia away from point of origin....I suppose that would be dispersion or wet on wet)
Blend ( how much the new colour blends with existing colour)

Nvidia 650m with 1 gb vram

I know these are already present in one form or another...its just that its not obvious how to get the desired result.
Ive figured out some dial settings that get me there but I still dont fully understand what each dial is doing to the mix.

I also think it is important to consider the fluids in two very different context.
The volume thick paint is BEAUTIFUL but so is the PURE FLUID WATERCOLOUR with no volume.
But they behave very differently....one wants to pile up and tug and spread while the other wants to bleed and wander and mingle.
I hope you will give the pure fluids as much love as the volume when tweaking.

Anyway....said too much already
its all delicious
and Ive have to ween myself off the addiction of your developmental updates
It was like when I got my first cassette tape based answering machine in the 80s
If the red light was not flashing when I got home I became depressed feeling like nobody loved me....;(
So I just smile now when I see a new version number and wonder...
what has the mad scientist come up with nowÉ

Ah yeah, that's interesting. I'm sure some of the stuff I've added would require more computation, while at the same time I've eased the burden on others. I am constantly going through everything and every step forward is really just something that widens the spectrum of what I can incorporate eventually.

You should try to turn the canvas off and tell me, if u.26 is still more sluggish than u.20 then?!

BUT it may not even be the fluids, but the brush 9 that causes it to be slower, depending on the rest of your machine specs. Just try it with brush2 to compare the versions!

However, a key aspect of the new fluids is that they are "more correct" in the texture interaction. That's rather exciting, because it slowly suggests a chance for a healthy paint on paint interaction, hehe.
There are a number of things that will benefit from what I've figured out, you'll see.

The other thing is, the more "accurate" things are supposed to get, the more speed will have to suffer. My fluids, for example, permit leaping over several pixels with their velocity. Really accurate fluids could not do that, because vital interactions between point A and B would have to be processed properly and propagated into the rest of the fluid space. SOoooo it'll never be completely accurate, but it'll also be far more artist friendly than anything that would be. I've seen MoXi, for example, and the new thing from the maker of it, and it is beautiful, but it is slow as heck. You basically have to mediate and enjoy watching water soak into paper...it won't ever be anything like Verve, I'm quite sure. I could consider hooking up modes that would support such accuracy, but I have a feeling it won't be used all that much. But who knows?!

There's one more thing that could actually affect the speed. I'm not doing event based input, which is very different to what I used to do. I'm not yet entirely happy about it, because on my wacom it feels like the brush can hang and keep painting without pressure, which shouldn't be possible at all. Not sure what black magic goes on there, but sense it makes none. Anyway...it's another potential slowdown.

Thanks for testing and comparing like that, of course!

Hey Stavros, can you download it again and try if it has changed at all? If not, then I'm pretty sure it's not the GL. If it is notably faster, then it was GL.

Hi Taron,

If I use [m] secret hotkey and fluidity > 0 after the moment I get only black color instead the yellow. Look at the attached picture please.

From top:
1. fluidity=0, ok
2. fluidity=100%,ok
3, fluidity=0, [m] key, ok
4. fluidity>0, [m] key, ko

I have ATI Radeon.

I tested on my notebook with ATI mobile at the office and I cannot reproduce this issue there..

Interesting issue. It looks like oversaturation behind the limits but what I know. Can you check please?

[Taron]

YEAh, the stupid, stupid, stupid ATi crap... what ever the deal is there, but it drives me nuts as long as I don't have such a system here to test. You may have troubles with chroma smudge, too, probably not doing a thing?! No idea what the deal is. But eventually I'll be able to track most of it down. The black crap there seems to be a clipping thing, but it shouldn't possibly do that... ...crazy.
NVidia is really the best in terms of being intelligent in interpreting GL. I don't care what anybody says, ATi is hellishly annoying.

So you must send a NVidia with each version of Verve!

[Taron]

No, if you just need an Nvidia card once, hehe! Life's good after that!
