Chapter 349 3D game engine is very troublesome

"I can take you to knock on the door of adventure, but it's you who opens this door to challenge fate."

"This is the harshest and most adventurous motorsport in the world, and it is the game of the brave!"

"The whole journey is more than 8,000 kilometers, spanning the European and African continents, away from the highways, uninhabited, with steep terrain and harsh climate. Most of them are in tropical deserts, with high temperatures exceeding 40 degrees during the day and below 0 degrees at night. This is a test of human endurance!

"In the 1995 Paris-Dakar Rally, CCTV Sports Channel followed the filming throughout the entire process, and shocked! Longteng Entertainment Games Company recruited volunteers and drivers from all over the country. Who would become the first Chinese driver to challenge the Dakar Rally?"

This is an advertisement for CCTV Sports Channel. After CCTV One was broadcast, it instantly attracted the attention of the people across the country and sparked a heated discussion!

The specific recruitment conditions were published in the Sports Weekly for four consecutive periods. The conditions were very strict and had very high requirements for the driver's physical fitness, driving experience, age, psychological tolerance, and reaction speed. These are all hard indicators.

In addition, China will send two teams to participate, one is the seed team, the Shanghai Shark Team, all vehicles and parts are imported from the United States, and will be guided by General Motors GMC pickup branch, technician training and support vehicles.

The Shanghai Automobile Group is responsible for this. This is the first unofficial cooperation between SAIC and GM, aiming to establish a good exchange relationship.

The second is the friendly participation team, the Great Wall Longteng team, which is equipped with a modified pickup truck provided by Great Wall Motors, and drivers are publicly recruited by Longteng to the whole society. Walking with CCTV Sports Channel reporters, the focus is on participating. There is no pressure to compete.

Although there are now joint ventures such as Jiangling and Nissan in China to produce pickup trucks. The technology and quality are better than the domestic Great Wall, Jiangling is Japanese Isuzu technology, not to mention Nissan, so Longteng’s ultimate choice is to cooperate with domestic Great Wall Motors.

Within Longteng Company, employees actively responded to the call and signed up for the reinforcements team to participate in the rally, were willing to follow the large army to challenge the limits, contribute to the company, and volunteer.

Looking at the thick stack of lists collected, Zhao Yongping laughed in silence: "Mr. Yang, do these guys think they are traveling to Europe? This is a race that kills several lives every year. The average speed of cars is 150 kilometers per hour, and the average speed of motorcycles is 130 kilometers per hour.

Kilometers, if you accidentally get rid of the car, you will be killed and smashed to pieces!”

Yang Yun sighed: "So it is challenging! The support team cannot follow the track and walk on a stable road, so we only need to send out two maintenance technicians with photography equipment, and also have the desire to support logistics.

The person still chooses experienced veterans from outside. In addition, what I am worried about is the driver and follower reporter in Great Wall Car. If the quality of the car is not good and the drivers are not experienced enough, it is easy to get into trouble."

Zhao Yongping said: "Mr. Wei of Great Wall patted his chest and said it was okay. He would gather the best technology in the factory to transform the vehicle. In addition to the fuel tank with a range of 800 kilometers stipulated by the competition organizing committee, the engine's cooling effect must be enhanced.

, increase horsepower and torque. Replace the top imported engine oil from abroad, strengthen the chassis beams. Add double-layer car beams, increase suspension travel, etc..”

"So many modifications... can Great Wall be made?" Yang Yun couldn't believe it. He only knew that Great Wall started with a pickup truck, but now he didn't seem to see mass-produced models being taken off the production line.

Zhao Yongping was very sure and helped to say good things: "I have been to the laboratory of the Great Wall Factory. They are planning to launch mass-produced pickup trucks the following year. Next year's Dakar Rally is a good opportunity to test the quality of the product. Not to mention how many places you get,

As long as the competition can be completed safely, it is enough to show that the quality of the Great Wall pickup is good, and this is the best advertisement."

"Ha!" Yang Yun laughed: "If this is the case, their engineers will definitely kill this test vehicle. There are more than 60 modification terms allowed by the Dakar Rally, and now there are some

They are busy!"

Zhao Yongping laughed and said, "That's right! And the Great Wall is from Baoding. The capital has issued a deadly order and the participating teams must be drawn out at all costs. In order to ensure success, the superiors used administrative means to transfer some senior high-level people from his factory.

The technicians, all of them from Nissan and Mitsubishi, went to Great Wall to help, making them look like a domestic car battle…”

"Oh, it's better to ask Chinese automakers to send technicians to Japanese factories to guide their work. Okay, that's it! The most important thing is to ensure the safety of personnel, and then bring enough cameras and repair accessories on board. You must put them in the car.

The real scene of the rally race was filmed!" After Yang Yun explained these, he came to the experiment center again.

The 3D game engine of "Stereo-3" is in the final running-in period. After Zhang Guoqiang's research team got the latest physics modeling from KTT Yu Suzuki, they launched project cooperation with the Department of Physics Laboratory of Tsinghua University, and simultaneously launched multiple action models.

Simulation.

Looking at the animation of the rolling trajectory of a rectangular object simulated on a computer screen, Yang Yun frowned and asked, "Is this a model of objects rolling on the flat ground? It seems a bit simple!"

Zhang Guoqiang nodded: "Yes, the object's running speed, collision angle, centrifugal force, friction force, and various parameters can be set, which can perfectly simulate the result of two cars after a rapid racing collision."

Watching Zhang Guoqiang open the source code and find a long list of functions with the same function names, different parameters, but implementing the same function.

This program pattern is called reconstruction, such as a function called "roll", which may have four forms.

Roll (no parameters), roll (parameter 1), roll (parameter 1, parameter 2), roll (parameter 1, parameter 2, parameter 3), parameter 1 is a roadblock, parameter 2 is a vehicle obstacle, parameter 3 is an environmental attribute

.

In the game, the vehicle loses control due to the centrifugal force of high-speed cornering, and can directly call the tumbling (no parameters) program to see the standard tumbling animation.

When hitting a roadblock or hitting other vehicles, the rolling effect of the vehicle controlled by the player is slightly different from the rolling (no parameters). The rolling model will add the physical trajectory of the roadblock and other collision objects. It is necessary to use a complex physical model to simulate the outflow of the roadblock.

Animation of crashing and several cars rolling over at the same time.

The parameters of environmental properties are the same. There is a corresponding physical model for rainy days, muddy land, and frozen ground, and the corresponding vehicle rolling simulation animations are all unique.

Of course, the function of vehicle rolling is far more than these four forms. The vehicle's own attributes, center of gravity, horsepower, torque, turning angle, external environment may have more complex serial collisions, tire wear time and reduced grip, etc.

And, it can be said that there are countless parameters that affect the effect of rolling over.

Therefore, in order to realistically simulate the real environment, the "Stereo-3" game engine needs more and more complete functions!

Yang Yun said: "These should be more suitable for urban supercars. The terrain of the Dakar Rally is too complex. It has no collisions, only challenges with cruel nature. I hope you can make the model richer."

The requirements for the Dakar Rally are higher. A small sand dune, a piece of ruins, dead trees hidden under shallow sand, or simply gravel sand roads that last several kilometers long, the impact on vehicles is everywhere, "

The Three-dimensional No. 3 engine needs to build more physical models!

Zhang Guoqiang nodded and smiled: "We have already thought of this! A year ago, we cooperated with the Department of Physics of Tsinghua University. The object motion modeling of the three-dimensional engine No. 1 was what they helped to improve. "Tomb Raider" used 2

Now I have sent back a number 3 used in the Dakar Rally. The physics laboratory of Tsinghua University is so busy that I can’t afford it!”

Next, he quickly explained the details of the cooperation between the two parties, and interspersed with a few pedantic old master's jokes in the middle, making everyone laugh continuously.

"Okay, pay attention to patent issues and keep it confidential!" Yang Yun gave another sentence and signaled Zhang Guoqiang to demonstrate "Tomb Raider".

The game "Tomb Raider" has been designed for half a year, and it has been fully prepared last month. The program runs smoothly, the number of secret locations is rich, the location is hidden, the animation cg and the story plot are complete, and it can be made into an installation package at any time.

, encrypted and burned to CD for sale.

Before Yang Yun signed and passed the acceptance, the programmers of the Tomb Raider R&D team modified the code, tested bugs, or transplanted new technology from Engine 3 to the existing version every day.

"Not bad, the new SS rocker handle!" Yang Yun pinched the new SS handle with the rocker, pinching his fingers everywhere, and found the feeling of playing PS games in Sony Game Room.

Although this handle is not his favorite style, it is enough in this era. He can't wait to try the feeling of using a rocker to control the cursor.

The game begins, after a erratic and grim cutscene music, the words "Tomb Raider 1 - China Prequel" appear on the TV screen, and a female character with a big braid comes out and stands in a closed tomb

Standing in front of the gate with a gun.

Yang Yun opened his eyes wide and looked at the model of the character carefully.

It is still composed of a large number of mosaics, but these mosaics are very small, which is much better than the expressiveness on the md platform. After all, this is a 32-bit graphics card specially made by ATI for Longteng, and its graphics reconstruction ability is quite excellent.

Looking at the face that was 70% or 80% similar to Angelina Jolie, and the concave and convex figure that was almost the same or even more exaggerated, Yang Yun smiled at the corner of his mouth, which he intended to arrange it like this.

Julie can play Laura within ten years, which is a role tailor-made for her. But after the age of 30, Julie is old and has done a foolish thing to cut off her huge chest. At that time, she was the second time to work hard.

If you pull, you have to replace someone.

The Chinese-style Tomb Raider game begins! (To be continued, please search for Astronomy, novels are better, updated and faster!
