Chapter 245 243. Is this effect too awesome?

Once Bomi's X2 game engine promotional video was launched, it immediately attracted the attention of developers of various domestic game companies.

The owner of Jianwang 3 in Xishanju, Rao Lin and his colleagues have been together for a long time to watch the new promotional video of Bomi X2:

A large forest of maple trees appeared in the screen.

Some of the leaves in the maple forest are still green, and most of them have turned into fiery red or orange. They look mottled, but they make you feel like a large fire is burning.

Blue sky and white clouds.

As the sun swept through, the light penetrated through the gaps of the leaves, leaving a subtle color on the ground.

"The light and color are a bit amazing," said an art classmate next to him.

"But it's not particularly amazing. The engine effect looks like a light, but the color matching of these maple trees and maple leaves is still well done by others."

"Yes." Everyone exclaimed.

Bomi not only has the best engine developers, they also have the best art team.

Damn, even if you don’t have an engine, just the composition and color matching of the picture are really amazing.

In art, color matching is actually the most difficult. This thing is just like the orchestration when creating music. You have to grasp the effect of the colors when they are mixed together, so that players can feel the reality and also feel the beauty without causing the whole picture to be too complicated and give people a dirty and disorderly sense. It is quite difficult to do this.

It is obvious that the blue sky and white clouds surrounded by maple forests in the picture now reflect this point. The picture quality is quite high, and at the same time, you can see the combination of freehand oriental painting and the real environment.

This feeling is really wonderful. You know it is fake, but it is so fake that people are willing to believe it is real.

And you can see traces of Chinese ink painting style at a glance, the freehand feeling of maple forests and maple leaves floating, which is not something foreigners can easily grasp.

However, the amazement was not over yet.

A fallen leaf slowly fell down.

The maple leaves fell on everyone's faces, and followed by the entire sky, including the maple forest before, and a gentle sway.

"Damn!"

A ripples spread out, and the whole camera pulled up.

The sky hangs backwards, and the whole picture turns backwards.

It was at this moment that everyone realized that the realistic effect I had seen before was actually a scene reflected from a quiet pond.

Everyone was shocked.

"The effect of this water is too awesome, right?"

"Yes... who could have thought of it? This is a damn...X2 and X1 are completely different things. I feel like I jumped from the primitive era to the industrial era."

Yes, not long ago, the water made by the X1 engine was a bit [greasy], and it looked very average in reflection and mirror effects and water material fluctuations.

In other words, before X2 was not available, the industry felt that it was the best water material.

Although it looks a bit greasy and is just a thin layer of dough, the water not only has the texture fluctuations of the water, but also produces a certain light and shadow effect.

However, compared with X2, the water effect of X1 is simply terrible.

In game art, there are several things that are difficult to do and costly.

The first is light, because the role of light in the game is quite huge. Light brings you not only changes in light and darkness, but also changes in material and color. So Monet spent most of his life painting the valley pile in the fields, but in fact he wanted to study the effect of light through the changes in the valley pile.

Then to judge whether an engine is awesome or not, it depends on its processing of light.

Light will be divided into real-time light and static light.

Static light is easier to deal with. Basically, the engine does not need to do too much calculation. Art can draw the corresponding light of the static object based on daily experience. Because the light source does not move and has no external influence, the light can be made into static, that is, fixed, or dead light.

For dynamic light, in the natural environment, a beam of light hits an object will produce many effects, such as diffuse reflection and specular reflection, and there will be refraction effects on objects such as glass that have transmission effects. You can take a few things at home to observe them. When the object is closer, the diffuse reflected light hits other objects, which affects each other, and this reflection can theoretically be performed countless times.

This thing is quite complicated.

For example, at night, a flashlight suddenly lit up, and then all visible objects that can be seen on the path of the flashlight will change due to the influence of light. The most direct thing is that the shadow will pull and change differently as the light is exposed.

The second is water. The transparency of water itself is difficult to deal with. At the same time, water also has a mirror effect, which means that water can reflect the things it reflects, and these things will change due to the change in the shape of water.

Therefore, the second difficult point of water treatment is its instability, or variability.

It's really hard to do it well.

So when everyone saw the demonstration effect of Bomi X2 engine on water, they all exclaimed.

"This is too strong, right? How did they do it?"

"What awesome, I don't know how to describe this water."

"The effect of this water fluctuation effect reflects the surrounding maple forests so good... I envy Bomi's art team so much. With such strong technical support, no wonder Bomi can now become the leader in the game industry."

"The X2 engine can be said to be the world's number one now, right?"

"Is this a big deal? It's already been during the X1 period, right?"

"However, I think it's really great that Boss Cao is willing to open source the X2 engine. After this thing comes out, I must study it carefully. With X2, our company's game quality will probably be improved a lot."

"Yeah, if you want to know how others do it, don't you know it by looking at the code? I feel it's really not easy." said Master Mei Rao Lin.

Among the art team, there is a profession called TA, TechnicalArt, also known as technical art, which is a two-way compound talent with code skills and art skills. The role of TA is to study the latest and most cutting-edge engine technologies to solve technical problems for art students, and also to develop engines or magic engines.

The birth of this profession is mainly used to make up for the embarrassment of programmers not understanding art or art does not understand programs. If both parties do not understand each other's needs, it is actually difficult to do many things. Therefore, the profession of TA was born, which is equivalent to a bridge and plays a key role in good communication between programs and art.

Therefore, many large companies are equipped with TA positions.

Cao Yang was equivalent to a TA before, or the position of a top TA in China.

He graduated from the Qing Dynasty University computer science department and his ability to write code is not very good, but he is not bad. In the field of art, Cao Yang's ability is the best. His painting skills, imagination and creative design skills are all first-class in the country. Now that he is reborn, he is even more abnormal.

In addition to Deng Peiqiang's team's great player, Cao Yang really made an indelible contribution to the X2 engine being able to do so well.

Unfortunately, the outside world knows too little about his business ability. Otherwise, Boss Cao's perverted and comprehensive technology would have caused many people to be shocked.

...

In the picture, as the camera reverses, on the ground, one foot stepped on the fallen leaves piled up by yellow and green, making a rustling sound.

A girl appeared on the screen.

She was wearing a worn out dress, and the marks of needlework on her cuffs were clearly visible.

A pair of slender thighs were exposed on the hem of the clothes.

A long streamer was tied to the girl's waist.

She wore a mask on her face, and the bangs on her forehead swayed in the wind.

"This character model feels average, but the material of the clothes is pretty good. This feeling of being old and dirty is very textured." An art sighed.

The model has not many faces, so the fineness is relatively limited.

In order to reduce the consumption caused by hair, girls' hair is tied into a high ponytail.

The ponytail is very long and droops all the way to the waist.

If you want to make hair in detail, it can be said that it has no limit, but it brings huge consumption.

If you want to have that feeling of flowing hair, you have to split it into n surfaces, which brings an extremely high consumption. In 2005, ordinary machines could not hang up at all.

When Guo Xiaosi was doing "Juezhi", Fan Ye's hair was so fatal, thick, long and much more. If they wanted to make a silky feeling, they had to have at least 4,500 hairs to do it.

Each hair is a polyhedral, and it is not just a simple shape like a cube, but a complex structure of n polyhedrals together.

Loading alone is difficult, not to mention having 4,5,000 hairs like this.

So later, in order to reduce the expenses, Guo Xiaosi could only let Fan Ye tie his hair up and make a model, so that he could control the number of faces.

Now in the promotional video of X2 engine, the image of a girl is a bit similar to this one. In addition to the bangs floating on her forehead, her hair is tied up and tied with a ribbon to the back.

The art teams in Xishanju are all old art, so they naturally know what the reason for doing this.

However, this model has a strong sense of design and outstanding details, so it won't make you think that even if she tied her ponytail, it will reduce the quality of the game.

It was at this moment that the dark clouds in the sky gathered, and the light and shadow on the girl's face changed.

“Wow!”

The artists exclaimed.

This was something they didn't expect.

Just now everyone was muttering about the dynamic light effect of the X2 engine.

Now I will show you a light show.

Half of the girl's body was shrouded in the shadows. As the light changed, the effect on her face was also changing, and the shadow behind her and the effect of falling leaves on the ground also changed.

Although it is not real enough, compared to X1, X2 is a qualitative leap.

"This dynamic light effect is a bit awesome!"

However, the sharp-eyed art noticed that the reflection effect of the water below the heroine was not so realistic.

Perhaps it is because the superposition of water materials and light effects is difficult to deal with, and there has not been any special progress in the algorithm. This year, Nvidia has not developed an updated graphics card, and its support for dynamic light is relatively limited, and it is far from the [Ray Tracing] level in 20 years.

Now Bomi's X2 engine only applies dynamic illumination rendering, and is far from reaching the level of ray tracing. In other words, the light effect presented now is the material and light changes caused by the light irradiation parameters. If it is real ray tracing, then more superposition effects will be generated, and the calculation overhead is very huge.
