2. Draw multiple cubes, arrange them in order, name them, and remove the meshender attribute (no rendering), which is equivalent to drawing a grid, which is easy to understand
3. It's troublesome to judge the range with two-dimensional array (mainly integer), The simple way is that the computer obtains the original coordinates of the model (such as the center point of the model). When the absolute value of the x value (and y value) of the mouse's real-time coordinates minus the original coordinates is equal to the side length of the square, the square (or other dry points) will be displayed with the real-time coordinates as the center, The real-time coordinates are used as the original coordinates for the next step

In March 2019, Tesla sued Cao Guang, a former Tesla employee working for Xiaopeng automobile, for plagiarizing the autopilot code. Cao backed up the compressed files of autopilot source code when he was a senior Tesla engineer. After investigation, it was confirmed that the files had been deleted when he left Tesla. According to auto first, in addition to Cao Guang, a number of engineers who have worked in Tesla have joined Xiaopeng. Among them, Gu Junli, who used to be the head of machine learning at Tesla autopilot, joined Xiaopeng automobile in January 2018 as the vice president of autonomous driving research and development. In March this year, Gu Junli left Xiaopeng automobile. According to a person familiar with the matter, Xiaopeng automobile has used Tesla's open source code in driving aid software. As many core engineers come from Tesla, based on the accumulation of these engineers for many years, it is inevitable that they can learn from Tesla's software development experience
Xiaopeng automobile has been ahead of the new car makers in terms of auxiliary driving such as automatic parking. In the first quarter of next year, Xiaopeng automobile will launch high-speed autonomous navigation driving NGP. Wu Xinzhou, vice president of automatic driving of Xiaopeng automobile, said that the system will be mainly considered from three dimensions: scene coverage rate, manual access rate and lane changing efficiency, so Xiaopeng automobile will invest heavily in hardware, It includes: 14 cameras, 5 millimeter wave radars, 12 ultrasonic sensors, in addition, it is matched with high decimeter level high-precision map, GPS + RTK + IMU centimeter level positioning, NVIDIA Xavier computing platform, Bosch ibooster brake assist system
in order to ensure safety, Xiaopeng car has made rendancy in software and hardware, such as braking. In order to ensure stability and safety, two sets of software systems are used in P7, namely xpilot3.0 and xpilot2.0, which are completely independent and mutually rendant. He Xiaopeng, who came from UC software, has a deep understanding of intelligent vehicle software architecture. The self-developed part developed with suppliers has been incorporated into his own system, including perception, planning, decision-making, control, etc
overseas, many people call Xiaopeng as China's "Tesla". Xiaopeng, which has just been established for six years, obviously lags behind Tesla in terms of software defined cars, driverless data, chips, and three electric technologies, and Tesla is also graally evolving. Wang Wenjia, engineering director of Tesla Asia Pacific region, disclosed that Tesla will develop automatic parking based on ultrasonic and visual perception in China to improve Tesla's automatic parking ability for narrow parking spaces
according to the official data of Xiaopeng automobile, the total delivery volume in October reached 3040 units, a year-on-year increase of 229%, reaching more than 3000 units for two consecutive months. From January to October this year, the cumulative delivery volume of Xiaopeng automobile was 17117, with a year-on-year growth of 64%. Xiaopeng P7 delivered 2104 vehicles in a single month, reaching more than 2000 vehicles in a single month for two consecutive months, with a cumulative delivery of 8639 vehicles. Tesla's third quarter results show that 318900 vehicles were delivered in the first three quarters of this year, and the sales target of 500000 vehicles is expected to be achieved by the end of this year. The financial report also shows that Tesla invested $366 million in R & D in the third quarter, while Xiaopeng invested about $93.6 million in R & D in the third quarter, which can be seen from the market and R & D investment scale of the two companies. He Xiaopeng, who is technically on the same level as Tesla, obviously has a long way to go

I think the performance of Xiaopeng P7 is very good. With the help of front / rear al motors, the dynamic response of P7 is very fast. When you need power from the power system, the switch response is very direct and the ride comfort is also very good
the steering wheel grip is good, but the setting is not gentle. This setting will be very suitable for us to drive. P7 adopts the combination of front double wishbone independent suspension and rear multi link independent suspension, and is equipped with CDC variable damping damper provided by Sachs. There are comfort, standard and Sport modes for you to choose from. The chassis adjustment has reached a high standard for vibration filtering, the suspension support effect is very good, and the rendant shaking of the body can hardly be felt. In terms of power, Xiaopeng P7 is divided into al motor four-wheel drive performance version and rear drive ultra long enrance version. The former has a comprehensive maximum power of 316kw, a peak torque of 655nm, and an acceleration of 0-100km / h takes only 4.3 seconds; The maximum power of the latter is 196kw, the peak torque is 390nm, and the official 100 km acceleration time is 6.7 seconds; In the enrance part, the former NEDC has a comprehensive enrance of more than 550km, while the latter NEDC has a comprehensive enrance of more than 650km. In terms of battery, Xiaopeng P7 is equipped with the latest generation of square battery pack, using Ningde era cell, with rated energy of 80.87kwh and energy density of 170wh/kg. At the same time, the motor, electric control and recer are highly integrated to form a high-performance three in one electric drive system. Compared with the traditional distributed electric drive layout, the three in one electric drive system has higher efficiency, more compact structure, lighter weight, more regular interior layout and stronger reliability. The battery pack has reached the highest level of IP68. I think these configurations make Xiaopeng's performance go up a ladder,

first, the big screen is still cool
this year's newly released Android mobile phone screens are bigger than one another. It seems that the big screen can really bring super cool visual effects, especially when watching videos or playing games, the big screen has inherent advantages. When the screen is big, the distance between the mobile phone and the eyes will be relatively far away. If you put the mobile phone on the table, the big screen can bring super cool visual effects, You can free your hands and enjoy the fun of video. Glory play4t Pro adopts 6.3-inch OLED panel water drop screen, 2400x1080 resolution, 418ppi pixel density, supports the new generation of screen fingerprint identification, with higher recognition rate and faster speed. The proportion of screen is as high as 91.17%, which supports Rhine eye care certification in Germany. Glory this screen visual performance is regular, support 98% of the wide gamut, can present users with a very delicate, realistic picture.
screen size: refers to the diagonal size of the screen, generally expressed in inches. For example, the main screen size of a mobile phone is 3.5 inches, that is to say, the diagonal length of the screen is 3.5 inches (one inch is equal to 2.54 cm)
screen material: with the graal popularity of mobile phone color screen, the material of mobile phone screen is becoming more and more important. The color screens of mobile phones are different because of different LCD quality and R & D technology. The types of color screens are TFT, TFD, ufb, STN and OLED. Generally, the better ones are IPS, SLCD, super AMOLED, etc. It's mostly used on iPhones and Samsung phones. Generally speaking, the more colors you can display, the more complex images you can display, and the richer the level of the picture
screen resolution: the definition of a mobile phone is not only determined by the screen material, but also greatly related to the screen resolution. The so-called screen resolution refers to the number of points per inch of the screen. The higher the number of points, the clearer the screen will be. 1.2 motherboard (chip & Handset & loudspeaker & transmitter & infrared & Bluetooth mole & GPS mole & gyroscope & main and auxiliary cameras & Flash & photosensitive mole & NFC
mole & Antenna & etc.) motherboard & Chip:
can call the integrated circuit board of mobile phone, he connects all the following hardware together through the motherboard:
the handset is a telephone, walkie talkie Mobile phones and other communication tools are an accessory for transmitting sound, which is a kind of loudspeaker, but it is not generally called loudspeaker. Generally, this word is used to describe the parts of electronic procts that transmit sound. Such as: mobile phone, walkie talkie, etc. Loudspeaker:
is an electroacoustic device which converts electric energy into sound energy. There are many kinds of loudspeakers. Although they work in different ways, they are ultimately driven by mechanical vibration to make the air medium fluctuate, so as to achieve the "electricity force sound" conversion. In short, calls, messages, alarm clocks, event reminders, etc. are all reminded through the loudspeaker
mobile phone speakers are divided into three parts: mono, al and stereo! In mono audio equipment, you can only feel the sound, the front and back position of the music, the timbre and volume, but not the horizontal movement of the sound from left to right. Generally speaking, there are two sound channels. On the circuit, they often transmit different electrical signals. In the process of pursuing stereo, e to the limitation of technology, electroacousticians only used two channels at the earliest time, so now stereo and two channels seem to be the same thing. Transmitter:
transmitter is a device used to convert sound into electrical signal, which converts voice signal into analog signal. Transmitter is also known as microphone, microphone, microphone, pickup, etc. Infrared:
before Bluetooth was widely used, it was used as a wireless transmission mode of mobile phone. The limitation is relatively large. First, the infrared interface of two mobile phones (or mobile phones and other devices) should be aligned, and then the distance should be within 10cm. The closer the better. There is no data line for wireless data transmission, mainly pictures and ring tones. The speed is relatively slow, and voice cannot be transmitted, so there is no "infrared headset". Later, Bluetooth has completely replaced the application of infrared, which is less and less. Bluetooth:
is a kind of radio technology that supports short distance communication between devices. It can exchange wireless information between many devices including mobile phones, PDAs, wireless headsets, laptops, related peripherals and so on. Using "Bluetooth" technology can effectively simplify the communication between mobile communication terminal devices, and also can successfully simplify the communication between devices and the Internet, so that data transmission becomes more rapid and efficient, and broaden the way for wireless communication
the most important feature of Bluetooth 4.0 is power saving technology, The extremely low power consumption of operation and standby can make a button battery work continuously for several years. In addition, it has many features, such as low cost, cross vendor interoperability, 3 ms low latency, over 100 meters long distance and so on. It can be used in many fields, such as pedometer, heart rate monitor, intelligent instrument, sensor Internet of things and so on, greatly expanding the application range of Bluetooth technology. Now 80% of mobile phones are equipped with Bluetooth function, and 100% of smart phones are equipped with Bluetooth function< Now Bluetooth 4.0 has gone into commercial use. Bluetooth 4.0 technology has been applied to the latest iPhone 5, Meizu MX2, the new iPad, HTC one X, Xiaomi mobile phone 2 and iPhone 4S. GPS:
the most important function of GPS is positioning, and the combination of GPS positioning technology and other technologies will proce many functions, the most common of which is navigation. At present, the GPS mobile phone is also a mobile phone with navigation function, so the GPS mobile phone can also be called a GPS navigation mobile phone or a mobile phone with GPS navigation function. In fact, with the development of technology and the opening of 3G network, GPS mobile phone will have more applications
wechat, which is now used by smart phones, has a shake function, that is, it must use GPS to get the location to search the nearby friends. There are currently popular software, such as Momo, meet, sing, etc. must use GPS positioning function
gyroscope:
or gravity sensor, a device pioneered by apple and now used in iPhone and ipod-nano4. The simple point is that when you hold the mobile phone in your hand, it is vertical. If you turn it 90 degrees and cross it, its page will automatically react with your center of gravity. That is to say, the page will also turn 90 degrees, which is extremely humanized. Main and auxiliary cameras:
mobile phone cameras are divided into built-in and external. Built in camera means that the camera is inside the mobile phone, which is more convenient. The external mobile phone is connected with the digital camera through the data cable or the lower interface of the mobile phone to complete all the shooting functions of the digital camera. The shooting function of mobile phone is directly related to its screen material, screen resolution, camera pixel and camera material. Flash:
it can emit strong light in a short time and is a photographic accessory for photographic sensitivity. It is mostly used for instant lighting in dark places, and also used for local lighting in bright places. Light sensor:
light sensor is also called brightness sensor, which is called light sensor in English. Many tablet computers and mobile phones are equipped with this sensor. It is generally located on the top of the handheld device screen. It can automatically adjust the brightness of the handheld device screen according to the current light brightness of the handheld device, so as to bring the best visual effect to the user. For example, in a dark environment, the backlight on the handheld device screen will automatically dim, otherwise it will be dazzling. The photoelectric sensor is composed of two components, namely a projector and a light receiver. The light is focused by the lens through the projector, transmitted to the lens of the light receiver, and then to the receiving sensor. The sensor converts the received light signal into an electrical signal, which can further perform various switching and control actions, Its basic principle is to use the signal obtained from the shielding action of the light between the projector and the light receiver to complete various automatic control. NFC:
NFC is the abbreviation of near field communication, that is, short-range wireless communication technology. NFC, jointly developed by Philips and Sony, is a non-contact identification and interconnection technology, which can carry out short-range wireless communication between mobile devices, consumer electronics, PCs and intelligent control tools. NFC provides a simple, touch based solution that allows consumers to exchange information, access content and services simply and intuitively. This function is mainly used for bus card, University card, consumption card, file transfer, etc. Antenna:
the RF signal power output by the radio transmitter is transmitted to the antenna through the feeder (cable) and radiated by the antenna in the form of electromagnetic wave. After the electromagnetic wave arrives at the receiving place, it is followed by the antenna (only receiving a small part of the power) and sent to the radio receiver through the feeder. It can be seen that antenna is an important radio equipment for transmitting and receiving electromagnetic waves. Without antenna, there will be no radio communication. WiFi / WiFi direct connection / WiFi hotspot:
WiFi: WiFi is a technology that can connect personal computers, handheld devices (such as PDA, mobile phone) and other terminals in a wireless way
WiFi is more and more widely used in handheld devices, and smart phones are one of them. Different from Bluetooth technology used in mobile phones earlier, WiFi has larger coverage and higher transmission rate, so WiFi mobile phones have become the fashion trend in the mobile communication instry
WiFi direct connection: Wi Fi direct connection, formerly known as Wi Fi peer-to-peer, is a set of software protocol, which allows WiFi devices to directly connect with another WiFi device in a point-to-point manner for high-speed data transmission without having to go through the wireless network base station (access point). WiFi hotspot:
WiFi hotspot is easy to understand, which means to convert the received GPRS or 3G signal of mobile phone into WiFi signal and send it out (send the signal through wireless form and USB connection form). In this way, your mobile phone becomes a WiFi hotspot. Wireless charging:
wireless charging technology is a technology that uses magnets to charge devices without wires. Wireless charging technology, originated from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between charger and equipment, while coils and capacitors form resonance between charger and equipment to realize efficient power transmission. CPU:
in daily life, mobile phone CPU is one of the functions ignored by shoppers. In fact, the most important part of a smart phone with excellent performance must be its "core", that is, CPU. Just like computer CPU, it is the control center system of the whole mobile phone and the control center of the logic part. It can also be called the brain of the mobile phone. The CPU plays an important role in the speed of the mobile phone. GPU:
GPU is full name of graphic processing unit in English and translated into "graphics processor" in Chinese. GPU is a concept relative to CPU. As the processing of mobile phone graphics becomes more and more important, a special graphics core processor is needed
ram running memory ROM storage memory
1.3 battery
mobile phone battery is an energy storage tool to provide power for mobile phone. Mobile phone battery generally uses lithium battery and Ni MH battery“ Mah "is the unit of battery capacity, the Chinese name is MAH
1.4 back cover
mobile phone battery cover, now many procts are mechatronics, such as iPhone, HTC and other procts. 1.5 SIM, USIM,
SIM card: SIM card is the abbreviation of subscriber identity mole, also known as smart card and user identity card. GSM digital mobile phone must be equipped with this card before it can be used. It stores the information of the digital mobile phone customer, the encrypted key and the user's phone book on a computer chip, which can be used to identify the customer's identity in GSM network and encrypt the voice information of the customer ring the call. USIM card: here refers to China Telecom Card standard card:
micro SIM card: Micro SIM card, also known as 3ff SIM card, which is the third type of SIM card. It was first used in Apple's iPhone 4 in the United States
nano SIM card:
nano SIM card is a 4FF standard SIM card, which was first proposed by apple and submitted to the European Telecommunication Standards Association
