Earth Plane DrawingThe Earth was a sphere, and there were many challenges to drawing it into a plan, which had troubled cartographers for centuries. The following is some of the content related to the drawing of the Earth's plane:
** 1. Traditional Projection Methods and Their Problems **
1. ** Mercator Projection **
- This was a projection method that many people were familiar with. It was a projection technology used by Google Maps for local maps, and it was also a common projection method for world maps in many classrooms.
- It was good at expressing local shapes, but it would distort when approaching the North Pole and the South Pole. It would distort the surface areas near the North Pole and the South Pole, causing these areas to be cut off frequently.
2. **Winkel Tripel Projection **
- National Geography used this projection in their world map.
- However, it still divided the Pacific Ocean into two, and there was a certain degree of imperfection.
** 2. New and Precise Drawing Method **
1. ** Double-Sided Gott Projection **
- The research was conducted by J. It was invented by Richard Gurt, Robert Vanderbei, and David Goldberg.
- This projection method divided the Earth into two halves and printed different halves on different sides, printing the map as a double-sided circle.
- According to their 2007 map accuracy scoring system,(The closer the score is to zero, the more accurate it is. For example, a globe can get a perfect zero, while the Mercator projection scored 8.296 points, the Winkel Tripel scored 4.563 points, and the two-sided projection scored 0.881 points.) This was a relatively accurate projection method, but technically speaking, printing a map on both sides of a piece of paper would bring obvious limitations, because people could not see both sides at the same time.
2. ** Double Pancake (Pancake) Map Projection **
- The researchers flattened the Earth into two pancakes, one depicting the northern hemisphere and the other depicting the southern hemisphere, with the equator running around the edge.
- These two "pancakes" represented a more accurate map of the Earth. Unlike other flat maps, this double-pancake map would not shrink or enlarge the area of certain oceans or continents. It was not like some very large triangular maps that could be held in one's hand and printed on a page of a magazine for the reader to cut.

anime character drawing, realistic eyesThe following are some realistic eye paintings of anime characters:
1. ** Basic outline and positioning **

When looking for the structure, he first used straight lines, then rounded them. He could also draw a rough outline and eyebrows first.
2. ** Description of details **
- ** Upper eyeliner **: Widen the upper eyeliner appropriately to draw the outline of the eyes, and add the corners of the eyes, keeping both sides synchronized.
- ** Eyelash **: The eyelashes at the end of the eye curl backward, the eyelashes at the head of the eye move forward, and eyelashes can also be added to the eye. You can also draw eyelashes according to the amount of hair and habits, and add thin and short eyelashes in the middle of the drawn eyelashes.
- ** Highlights and Pupils **: First, set the position of the highlight and determine the position of the pupil. The pupils were the deepest, and there was a gradual process from the top to the bottom. It could be layered and deepened layer by layer. He could slightly increase the outer line of the black eyeball, slowly stacking and increasing it, and then adding some small short lines.
- ** Shadows and other details **: Draw the shadow of the upper eyelid. The end of the eyelashes will appear thinner if it is directly drawn. It could draw details such as blood vessels. He could also add lines from the eye to the end of the eye as needed. In addition, the white of his eyes could be projected, and the lower eyeliner could be rubbed to create the corresponding effect.
- ** Color **: To determine the color of the pupil, draw the shadow and mucus membrane, adjust the color and add highlights.
