From scratch learn JAVA-3. Store and modify variable information in the program, java-3 variable 1. Create a variable; 2. Use different types of variables; 3. Store values in variables; 4. Use variables in mathematical expressions; 5. Assign the value of a variable to another variable; 6. Increment/decrease the value of the variable. Program Variable: use differe

to start the deep test. 2. When necessary (usually at the beginning of each screen), clear the depth buffer, that is, glclear (gl_depth_buffer_bit ); Here, glclear (gl_color_buffer_bit) and glclear (gl_depth_buffer_bit) can be combined:Glclear (gl_color_buffer_bit | gl_depth_buffer_bit );The latter may run faster than the former. So far, we can finally get the complete code of the entire "Sun, earth and moon" system. Code: # Include Result:

earth and crops, is generally emerald sky, when you see such a beautiful, interesting, unique page, you definitely want to continue browsing. 　　2. Can try more illustrations If you want to stand out from the crowd, try illustrations. Red Ape Design Company's official website is very interesting, the homepage makes full use of the space, to the work shows, the impact is very strong. Stereo Creative's homepage uses the pictu

mailing address, the universe, the Earth, the country, the province, the city, township, town, village are written in, 50 should be enough, hehe. So we're going to create the database now, we recommend that you use phpMyAdmin SQL to import the following statements, because this is the most convenient: Copy Code code as follows: CREATE TABLE ' Addr_list ' ( ' ID ' int (a) unsigned not NULL auto_increment, ' Name ' varchar not NULL

code Open the Arduino IDE's serial monitor to see the effect. /* Memsic2125 reads the pulse width of the memsic 21,252-axis accelerometer and converts it to the real acceleration and outputs it to the serial monitor. Circuit Construction: * Xout received number 2nd digital PIN * Yout received 3rd digital pin * +V received +5v * GND received GND code public */ /immutable constant: const int xpin = 2; Acceleration X-Axis Output const int ypin =

translation zoom to the earth corresponding to the inverse operation, I look at a globe near, such as forward 5m Actually, it's a globe moving towards you. 5m, similar operation, and I may want to look at the Earth from the angle of the plane or other angle overlooking the view, it needs my own rotation. In this way, all three coordinate systems for the Earth's construction are described here with the basi

applied ), therefore, it can be used in large-scale topographic maps to meet various military needs and perform precise measurement and calculation on maps. (2) Gaussian-kerluge projection band The earth's elliptical sphere is divided into several projection bands by a certain longitude difference, which is the most effective method for limiting length deformation in Gaussian projection. When dividing the band, you must control the length deformation so that it is not greater than the ing error

projection accuracy is high, the deformation is small, and the computation is simple (the coordinates of each projection are the same, as long as the data of one belt is calculated, other bands can be applied ), therefore, it can be used in large-scale topographic maps to meet various military needs and perform precise measurement and calculation on the charts. (2) Gaussian-kerluge projection band The earth's elliptical sphere is divided into several projection bands by a certain longitude diff

to simulate the earth, set its radius to the actual earth's radius of 5000 km. At last, according to satellite data, 900km of the sky above the ground can still see atmospheric traces, but 99.9% of the atmosphere is concentrated in the ground, 50km of the people in the middle of the ground and the lower layer. Therefore, when sphere gizmo is used to limit the nebula, the radius should be 5000 + 50 = 5050 km. 3
