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

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:

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

Open the Arduino IDE's serial monitor to see the effect.

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.

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.

Scientific superstition (3)
5. Science is limited.
At the end of the 18th century and the beginning of the 19th century, the Fog shrouded in nature gradually dispersed under the storm of science, and the absolute dominance of theology was not stable. For the sake of this scientific view, Laplace (Pierre-Simon Laplace) takes a closer look: "the status quo of the universe is the fruits of the past and the cause of the future. If a wise man (who later

falling in love with this stuff? Don't be happy too early, love is not a simple thing, it may bring you happiness and happiness, of course, can make you painful to jump. If you know it's hard to go on, I'm you!Keep working hard, maybe in the end you don't have to get true love (it's really possible, loved ones know), but you can feel the whole process of love, that's all. Sour, bitter and spicy, there is no sweet God knows.
Why does the batch process have anything to do with love? It's not that
