I was born by NVIDIA&Adobe collaboration, the simulator which "can draw a three-dimensional oil painting in real time" "Project Wetbrush"
"Oil painting" using a brush and paint is a three-dimensional work with depth information at the real world. A painting software of the digital world was 2D basically, but NVIDIA developed the world's first three-dimensional oil painting painting simulator which reproduces an oil painting with depth information in real time and minuteness "Project Wetbrush" in conjunction with Adobe research.

It can be confirmed by the following movie what kind of technology Wetbrush which figures a digital oil painting in the real time which becomes first in the world is.

The digital oil painting which drew a picture seen as only this real oil painting by the real time three-dimensional simulator made with Adobe research and NVIDIA "Wetbrush".
When the angle where a picture is seen is changed, shadow and gloss change because the oil painting drawn by Wetbrush has solid information. This is just same as a realistic oil painting.
The state which draws a picture in Wetbrush is such feeling.
A brush tool is used, and the color of the paint is changed, and it's same as a general painting software. I'm going to calculate the big feature of Wetbrush by real time until a movement of hair of a brush and produce the realistic "picture" like being real.
Such as a creator receives inspiration from the painting drawn by an oil painting in spite of realistic digital, it's said that they can write up creativity. The world's first simulator which can draw the oil painting which is a special work for the creator by canvas of the digital world is a reason as Wetbrush.
Three-dimensional structure of giblets of an oil painting is reproduced by the thing which makes information on the Z axial direction last by a layer in Wetbrush.
It's possible to reproduce the shadow applied by this by real paint. A simulation can also reproduce the special quality of the paint for which special Isshiki can be made with to mix the color of the paint of course in real time.

Adobe research has developed algorithm of the real time rendering which becomes a core in 2015 in case of realization of Wetbrush. It's said to be Wetbrush that the algorithm was optimized and made a practical use of by GPU in NVIDIA with parallel data processing of the supercomputer order.
It's said that Wetbrush is only the one which indicates the technological example GPU achieves according to NVIDIA, and Wetbrush learns, and is more realistic and suggests a possibility which becomes high-quality brush judgment by itself by mechanical learning by Deep learning for which computing power of GPU was utilized.

NVIDIA＆Adobeコラボで生まれた「リアルタイムで3Dの油絵を描ける」シミュレータ「Project Wetbrush」
筆と絵の具を使う「油絵」は、現実世界では奥行き情報を持った3Dの作品です。デジタル世界のペイントソフトは基本的には2Dですが、奥行き情報を持つ油絵を、リアルタイムかつ精緻に再現する世界初の3D油絵ペインティングシュミレーター「Project Wetbrush」をAdobeリサーチとNVIDIAが共同開発しました。

世界初となるリアルタイムでデジタルの油絵を描き出すWetbrushがどのような技術なのかは以下のムービーで確認できます。

この本物の油絵にしか見えない絵は、AdobeリサーチとNVIDIAによって作られたリアルタイム3Dシミュレーター「Wetbrush」によって描かれたデジタル油絵。
Wetbrushによって描かれる油絵は、立体情報を持っているため、絵を見る角度を変えると陰影や光沢が変化します。これはリアルな油絵と全く同じ。
Wetbrushで絵を描く様子はこんな感じ。
ブラシツールを使ったり、絵の具の色を変えたりというのは一般的なペイントソフトと同じ。Wetbrushの大きな特徴は、筆の毛の動きまでリアルタイムで演算して、現実と同じようなリアルな「絵」を生み出すところ。
リアル・デジタルを問わず、クリエイターは油絵で描かれた絵画からインスピレーションを受けるなど、創造性をかき立てられるものだとのこと。そのクリエイターにとって特別な芸術作品である油絵を、デジタル世界のキャンバスで描くことができる世界初のシミュレーターがWetbrushというわけです。
Wetbrushでは、レイヤーによってZ軸方向の情報を持たせることで、油絵のもつ立体構造を再現します。
これによって、本物の絵の具で塗られたような陰影を再現することが可能。もちろん絵の具の色を混ぜ合わせることで、特別な一色を作れる絵の具の特性も、シミュレーションによってリアルタイムで再現できます。
Wetbrushの実現にあたっては、Adobeリサーチが2015年にコアとなるリアルタイムレンダリングのアルゴリズムを開発しました。そのアルゴリズムをスーパーコンピューター級の並列演算処理を持つNVIDIAのGPUによって最適化・実用化したのがWetbrushとのこと。
NVIDIAによるとWetbrushはGPUが実現する技術の一例を示すものに過ぎないそうで、GPUの演算能力を活用したディープラーニングによって、Wetbrushは機械学習によって自分で学んでより現実的かつ高品質な筆さばきになる可能性を示唆しています。
