Why people don't paint on your computer? -Oil painting, digital, computer-IT news
Giant rotating nebulae, fire tossing Cypress, thick powerful slurry oil paints on canvas rolled curls up, forming vortex. Total Madness on the palette after the passage was understood.
You can see van Gogh works is being erased solid strokes.
Software has been pursuing traditional painting to oil painting brush strokes-like three-dimensional effect, but cannot match.
All application Adobe digital design company working with graphics giant Nvidia launched the world's first 3D paint application Wetbrush, people can finally paint on the computer. Wetbrush van Gogh painting of a solid into a 3D three-dimensional world.
Can you believe this is in the computer drawing it?
Use thick, oily color pictures piling up, is the most unusual paintings coloring.
Paint brush or palette knife can be used in reality, because of slow drying oil paints, negative pressure in painting process can, multilayer paint. Vincent van Gogh, Peter Paul Rubens, Rembrandt's paintings unique is that oil paints to create light effects and texture.

Switzerland Alps described by artist Conrad Jon Godly, thick texture and a unique sense of light, perfect example of the Alps the momentum.
Use enough paint brush or directly in the oil on the blade out of the painting, this painting is called "thickly"
General painting and drawing software unable to stroke in the complex reality, instead of using multiple layers and color overlay partition block rendering to create a 3D effect, if there is no professional training is difficult to achieve.
Imitate painting details and textures of real loss. That's why you see on the street "Star" and "cheap".
Wetbrush is the world's first 3D graphics applications based on real-time simulation, makes the painting on the computer and real world real.
A painting software is not new news, but brush movements and interactions in the real world can be simulated, which need large amounts of complex algorithms and powerful computing power.

? 3D brush to simulate the effect of
You know in the midst of a real scene, paint brushes, paint, canvas, pigments fluidity, viscosity, brush speed, two paint mixing, and even paint drying time required, all these things, and finally show the effect of oil painting.
Wetbrush established in the application of such a model can use true 3D simulation environment of oil painting effect. Natural brush strokes to create a canvas texture, needs to take into account the speed and intensity of brush painting, color blend effects, long even paint thickness of each pigment will take dry.
Of course, in addition to Adobe's digital synthesis algorithm due to NVIDIA video card CUDA physical operations in strong support.
Vincent van Gogh might never dream of one day, he can be arranged directly on the infinite well of color in the palette, you can conveniently choose any size of brush, or even any colors that you see in the real world.
Yes, full of happiness.
Use Wetbrush number no matter how much change the brush on the canvas, without washing, paint never runs out. Not a good color for an hour.
Adobe and who can have a stunning application, in 2014 at the Adobe MaX Conference, using Surface Pro 3 painting with gesture control is a kind of enjoyment.

No exaggeration to say that, Wetbrush's virtual painting and reality gap in small let up.
Even if it is not prolonged exposure to oil of turpentine in pregnant women and children, have created opportunities for such highly artistic paintings.
In the digital age before and now, if we wanted to use computers to create "real" painting, often requires a complex set of steps, through professional learning to become familiar with the operating system.
With the popularity of 3D and VR, whether Google Tilt Brush software or Adobe Wetbrush application, are in the virtual world of the painting's return "true" also agrees with habits of artistic creation in the history of mankind.
Does not require great skill, and tedious tutorial.
Technology to restore the fun of painting itself, in the most natural way to smudge and creation.
If we say that in the digital age, we looked to the artistic creation software what.
Allow everyone to enjoy the joy of creation, to the technology to do the rest.
为什么人们不在电脑上画油画？ - 油画,数字,电脑 - IT资讯
巨大旋转的星云，火浪翻腾的柏树，浓重有力的油画颜料浆在画布上翻卷缭绕，形成阵阵旋涡。调色板上的疯狂总在时过境迁以后才被人理解。
你所看见梵高作品是被抹去立体笔触的。
传统绘画软件一直追寻去呈现油画笔触般的立体效果，却无法企及。
包揽了数字设计应用的Adobe公司和显卡巨头Nvidia合作推出世界首款3D绘画应用Wetbrush，人们终于可以在电脑上画油画了。Wetbrush将立体的梵高画作塞进了3D的立体世界。
你能相信这是在电脑中画的吗？
使用浓稠、多油的颜色进行画面堆砌，是油画着色的最独特之处。
现实中作画可以使用画笔或调色刀，因为油画颜料干燥较慢，在作画过程中可以进行负压，多层涂抹。梵高、鲁本斯、伦勃朗的油画独特之处就在于油画颜料营造的光效与质感。
▲鲁本斯《El rapto de europa》
瑞士画家Conrad Jon Godly笔下的阿尔卑斯山，就用厚重质感与独特的光感，完美的展现了阿尔卑斯山脉气势。
使用饱蘸颜料的画笔或直接在油画刮刀上挤出颜料作画，这种绘画技巧叫做“厚涂”
普通的绘画与制图软件无法复刻现实场景中的笔触，而是使用多图层与色块的叠加，分区块的渲染来营造3D效果，如果没有专业的训练很难实现。
模仿，让油画作品的真实的细节与质感尽失。这就是为什么你在大街上见到的“星空”越来越有“廉价感”。
Wetbrush是世界上第一个基于实时仿真的3D绘图应用，让在电脑上画油画也变得和现实世界一样真实。
一个绘画软件的出现并不是什么新鲜的新闻，但能将真实世界的画笔动作与交互模拟出来，这就需要大量的复杂算法和强大的计算能力。
▲尚未干燥的颜料
▲3D笔刷模拟出的效果
要知道在真实的场景当中，画笔、颜料、画布都会相互作用，颜料的流动性、黏度、笔刷速度、两种颜料的混合效果、甚至是颜料的干燥需要多少时间，这些事情都和油画最后展现出的效果有关。
Wetbrush的应用中建立了这样一个计算模型，能用3D仿真模拟出真实环境下的油画效果。使用自然的笔刷笔触营造油画质感，需要考虑到画笔的涂画的速度与力度，颜色混合的效果，甚至包括颜料每种颜料厚度需要多久干燥。
当然，除了Adobe的核心数字算法合成还要归功于NVIDIA显卡中CUDA物理运算的强大支持。
梵高可能永远没有梦到有一天，他可以直接在无限的排列好的调色板中取色，可以随手选择任意规格大小的的笔刷，甚至可以任意选取现实世界中看到的颜色。
啊，满满的幸福感。
使用Wetbrush在数字画布上不管换了多少刷子，都不用洗，颜料永远也不会用完。更不用为了一个满意的颜色调上一个小时。
Adobe和谁合作都能有令人惊艳的应用出现，在2014的Adobe MaX大会上，使用Surface Pro 3用手势控制作画简直是一种享受。

不夸张的说，Wetbrush中的虚拟作画，与现实中的差距之小，让人眼前一亮。
哪怕是一些不能长期接触油画中的松节油的孕妇和小朋友，也有了创造这种极具艺术感画作的机会。
在现在以及之前的数字时代，我们如果想要用计算机创造如此“真实”的画作，往往需要极复杂的步骤，经过专业的学习来熟悉操作系统。
随着3D和VR的流行，不论是Google的Tilt Brush软件，还是Adobe的Wetbrush应用，都是让在虚拟世界中的作画也回归“本真”，同时也更契合人类艺术创造历史中的习惯。
不需要掌握高超的技巧，和繁琐的教程学习。
技术还原了绘画本身的乐趣，用最自然的方式进行涂抹和创作。
如果说在数字时代，我们对艺术创作软件还有什么期望。
让每一个人都享受到创作的乐趣，剩下的都交给技术去做吧。
