T* please a Hotkey for canvas texture ON_OFF

[Taron]

Your wish shall be my command today!
v0.99u.28 is up! With a number of changes, but also the added hotkey [T] to toggle canvas texture on/off!

Hi Taron, unfortunately yesterday evening Verve stopped responding (without any crash for long time) after I changed the brush type to #9 and tried to continue.. no save during that one hour of painting, my fault.. There were about 5 layers in the painting with the resolution 1920x1080.

Is it possible to automatically backup the drawing let's say after each 15 minutes or to show a warning that contains something like "Don´t be silly and backup your drawing!" ?

Is the brush #8 image based or hardcoded (described using mathematic formulas)? It would be nice to have an image based brush that we can load from a disc.. What do you think about it, Taron?

I will check new features today! Thank you, Taron!

Ugh...that's rough, sorry, Lemi!
Currently brush#8 is hardcoded fractals (with some parameters as you know and see. It's the same routine as for the procedural canvas). Later on I will have image based brush features for sure!
An automatic backup is good, but also could be trouble, because the saving takes some time, you know. Not sure how much anyone would appreciate it to get either interrupted by a sudden saving or annoyed by popups or the likes. Maybe a gentle reminder on the side could be good. THE BEST solution, though, would be if I somehow manage to not have it ever crash, hahaha.
I'll work on that, too. It's hard, because I hardly ever have crashes, you know. I should offer a "log" solution so people can report to me some more meaningful data.

Nice updates, U27 & U28 are special . T*.

First of all I'd like to join the chorus and compliment you on quite a phenomenal program. I'm stunned by how much it behave like natural medium, and my mind gets blown every time I open it. The possibilities seem endless. It will take awhile to figure out all the things I can do with this program, but that's okay. I've yet to master the variables of paint on paper.


If I might make a suggestion.
I noted your color wheel works in additive color space. This reproduces the effects of colors mixing in light, but the program simulates the physics of paint and medium on canvas. This seems to be a conflict. Shouldn't the color wheel reflect the neutralizing properties of physical color mixing? For example, if I mix complements like an ultramarine blue with a cadmium orange it will never make a white, but instead it would create a progressively more neutral blue until it reached a medium value gray. Perhaps the center of the color wheel should be a medium gray with the colors progressively increasing in chroma towards the outer edges. Then the lightest expression on the value dial should be white.
All this would create a color space similar to the Munsell color system.


I hope this suggestion adds fuel to thoughts.

Hi, B, and welcome to the forum!
Yeeeh...I'm well aware of that, but the color behavior is really not physically correct in Verve and only an approximation of mine to get effects more common to subtractive mixing. Presently my color wheel is literally the easiest and most direct way of dealing with native computer values in both picking colors and finding colors on the wheel again when picked somewhere else.
I sure hope that I will eventually manage to get more sophistication into the color system, but it will have to wait for a while. I'd love to get it working, though!

Thank you for digging this up and letting me know about it!

To give you a vague idea of just how deep those color troubles can go; presently I only run my better mixing system in the color motion process. It's not a simple routine at all, but it's not nearly as complicated as a full-on proper subtractive conversion would have to be. Then, once I'd establish that we have such color mixing, I'd have to hook it everywhere properly, suspending the use of openGL blending modes and doing even the transfer of paint onto the canvas via shaders. It will most certainly put much greater strain on the processing and will slow down everything. And it will do all this just to satisfy our expectations from real paint into a totally different medium that has all the power it needs to let us create images with any colors we like. So.... what's wrong with us? Why would we accept to suffer for the sake of simulating something that can never be as good in doing real life paintings as real life paintings would, but it can do enormously better in what it does than any real life painting could ever hope to accomplish!?

Just some food for thought back'atcha!

I said early on that I did not want to do a paint simulation, but have Verve be a tool to create art in its own rite, you know. I find myself wanting to get greater and greater depth in the simulation, though, because of the exciting effects and the great feel it can develop. But at the same time...well.... I don't want to abandon or ignore its true nature. I just want to expand it.

Anyway, if I can figure out an elegant solution, I will for sure!

I wouldn't want a color picker that seems to give you predominantly drab and gray tones unless you're near the perimeter. ick.
It's also very convenient that the entire Verve canvas is a wonderful active palette where colors can be mixed and sampled.

That sounds so great Taron - but please don't forget for a trick, that also GPU's with not so much VRAM can paint greater canvas
one friend did have this suggestion to VERVE & not so much GPU-VRAM

and wrote me in German

NAbend Geri, nur die sichtbare Fläche in den VRAM zu laden, wäre durchaus
eine Lösung, bei Linux greift Mensch auch auf solche Lösungen zurück.
Allerdings ist es dann beim Scrollen mit der Schönheit vorbei.
Dann wird an den Rändern dauernd das Bild neu aufgebaut, für Grafikeraugen
der pure Horror.
Was noch helfen könnte, wäre die Möglichkeit eines Menüs, nur die Effekte abzuschalten.
Baut man Effekte in die Grafik ein, so wären diese im Zeichenmodus nur als Text sichtbar,
in ihrer eigentlichen Wirkung siehst du sie dann im Betrachtermodus.
Da wäre aber dann nichts mit Zeichnen. Die Trennung der Modi wäre ein durchaus
gangbarer Weg, VRAM zu sparen. Schlag es ihm doch einfach mal vor. Cheesy

And this would be also neat:http://thisissand.com/ its not fluid, but if once a day we can maybe use gravitation / magnetfield in Verve?
